A survey aimed at obtaining information on the socio-economic potential (agronomic characterization, location, and marketing) was conducted in some locations in the provinces of Malanje, Huambo, Benguela and Huíla. The nutritional composition (dry matter, TSS, AT, pH, proteins, lipids, sugars, organic acids, insoluble dietary fiber, and mineral salts) was also studied using classical methods and through High Performance Liquid Chromatography (HPLC), the polyphenols and carotenoids were analyzed by HPLC using C18 and C30 columns, respectively and the aromatic compounds were extracted by Solid Phase Micro-extraction and analyzed by Gas Chromatography coupled to Mass Spectrometry. The results of the surveys showed that 79.2% are women, and all respondents do not know how much they consume per month, and they are interested in processed products. As for dry matter contents, they ranged from 24.71 (0.51) in Mixture to 20.24 (0.19) g.100 g1 in Huíla; NDF fibers (g.100 g-1 MS) from 20.99 (0.31) for Mixture to 15.48 (0.17) for Malanje; the most predominant sugar is fructose with levels (g.100 g-1 MS) of 15.98 (0.40) for Malanje to 14.93 (0.64) for Huambo. The fruit is rich in minerals mainly potassium, calcium, magnesium, and aluminum and in bioactive compounds such as polyphenols with 2303.04 mg Eq AG.100 g-1 MS for the Huíla fruit and carotenoids with a maximum content of 24.90 mg Eq B-C .100 g-1 MS in Huambo. The fruits presented 22 different aromatic compounds where the concentrations are quite variable.

Maria Mangumbala, M.Sc. ABSTRACT Care provided to the umbilical cord stump differs greatly depending on the country, region, culture, and caregivers. This care normally occurs at home and is usually provided by women in the family or close friends while the knowledge grounding such care is not always based on scientific evidence but on beliefs transmitted from generation to generation. Many of these cultural care practices conflict with those based on scientific knowledge as inappropriate substances or procedures expose new-borns to a high risk of neonatal tetanus and infection. Hence, this study’s objective was to identify care practices provided to the umbilical cord stump by mothers who delivered in the Lucrécia Paim Hospital. A qualitative study was conducted, and the study setting was Lucrécia Paim Hospital, Luanda, Angola. A total of 29 mothers participated in the study. Data were collected through semi-structured interviews, which were recorded and transcribed verbatim. Sample size was determined by reaching data saturation. Thematic analysis was used to analyse data. The results reveal three themes: 1) How to care for an umbilical cord stump; 2) The objectives of providing care to the umbilical cord stump; and 3) People * How to cite: Mangumbala, M. de J. (2023).

The mothers use alcohol and other substances/products, in accordance with folk knowledge, to facilitate disinfection and to cause the umbilical cord stump to drop off more quickly. Most mothers learn how to care for the umbilical cord stump within their families, also learning from folk knowledge as disseminated in the society. Such knowledge is highly valued by these mothers; only a few learned how to provide care from healthcare workers. The results also show that healthcare professionals do not provide guidance on how mothers should care for the new-born’s umbilical cord stump.

There are still gaps in the literature regarding maltreatment events in specific groups. Aim: To identify the relationship between physical violence and other forms of mistreatment in Malanje municipality, the pregnant teenagers from August 2nd to October 5th, 2022. Methodology: It is a survey of 137 participants in a singlestage cluster. Descriptive statistics, Pearson's chi-square test or Fisher's exact test, and multivariate analysis by logistic regression were applied at a 95% significance level. Results: Pregnant adolescents living in rural areas were 5.38 times more likely to suffer physical violence than those from urban/ peri-urban areas.

No significant association was found between physical violence and psychological aggression (AOR= 1.81; 95% CI. 0.55-5.96). Conclusion: Pregnant teenagers who are victims of non-violent abuse are equally vulnerable to violent acts. A permanent dialogue with families to promote violence-free education is needed, especially in more disadvantaged areas. Future studies should further explore geographic issues to generate more assertive strategies.

Environmental issues have been one of the problems and one of the objectives to consider when it comes to production scaling problems, mainly, minimizing energy consumption, and minimizing carbon emissions, as well as various other objectives to optimize. Measures that put pressure on organizations to pay more attention to the environment have been created, along with other measures, not only economic but also social. Good production scheduling allows organizations to be more successful in business, as it contributes to a better environment and society. Therefore, the search for processes that allow for more effective and efficient decision-making is becoming a subject of paramount importance to study. Sustainability is currently an urgent challenge for engineering and organizations. One of the ways to contribute to more sustainable manufacturing systems is the development of intelligent technologies and the sharing of manufacturing systems. This paper studies the literature on production scheduling approaches in distributed companies and their potential benefits for the environment and society, in addition to the economic benefits. In this way, the optimization of environmental, social, and economic measures in the planning and scheduling of production in extended company contexts, using approaches based on multio-bjective optimization, is a primary focus of this work.

From Entrepreneurship to Mathematics Teaching. A Practice (in the Informal Economy) of Sellers from the 5 de April Market in NamibeAngola * . (1) Alfredo Capitango de Lúcio, Ph.D.; (2) Celso Manuel Cristóvão Mandume, Ph.D.; (3) Vareny Flora P. de Lúcio, B.Sc. ABSTRACT This article aims to identify notable (Ethno)mathematical practices in commercial activities, among entrepreneurs/sellers in the reference market. We are concerned with knowing how these notable practices, in the informal economy can influence the teaching of Mathematics in the classroom, based on theories of (Ethno)mathematics. To meet the proposed objective and considering the nature of the topic, the research was developed using a qualitative methodology, through which information was obtained by a direct observation, and the application of semi-structured interviews to six informal sellers, with greater consistency and details of three sellers. After obtaining information, a reinforced analysis of reports was carried out, investigating knowledge of informal and implicit Mathematics, whose practices lead us to (Ethno)mathematical knowledge. Bibliographical research was also used using authors of * How to cite: de Lúcio, A. C., Mandume, C. M. C., & de Lúcio , V. F. P. (2023). Do Empreendedorismo ao Ensino da Matemática.

In short, informal sellers use an (Ethno)mathematics that they developed from the transmission of values coming from generation to generation, which allowed them to develop the four fundamental operations of Mathematics (Addition, Subtraction, Multiplication and Division), measures of weight and length. Identifying commercial know-how and considering the mathematics practiced by salespeople and school Mathematics teachers, we developed pedagogical proposals for teaching Mathematics in the classroom, for students in Primary Education and the first cycle of Secondary Education. The suggestions presented, will also serve as support/reinforcement for researchers and teachers, since the topic under study is open.

The current research article aims to identify and analyse the “concealed” mathematics through checker games played in Angola, mostly in Cuando Cubango province. The survey is placed in ethnomathematics and considering its nature, a qualitative methodology supported by a semistructured interview has been used, , in addition to a direct observation to picture recording. The research was conducted in Menongue municipality (Cuando Cubango capital city). The three versions of checkers games were described (12 by 12; 10 by 10 and 8 by 8), and some questions that guided this investigation were created: Why does the structure of the checkers game have the same number of rows and columns? Why do players when placing checkers pieces in the middle always leave two empty rows? Why are the sum of rows and columns equal to the even number? Why is each painted square on the checkers board corresponds to an odd number?) and, finally, some mathematical concepts involved in that game were explored (such as, for example, the notion of the Cartesian plane, diagonal lines, distance between two points, median (element of Statistics), numbers even and odd).

In recent years, the number of electronic scientific journals in Angola has increased, despite of their low visibility internationally. The objective of this article is to describe the profile of electronic scientific journals in Angola. This is an exploratory and documentary research, in which a total of 14 web pages of scientific journals were observed, using a form, containing a control list with the following items: year of creation, responsible institution, area of knowledge, periodicity of publications, last publication, indexing in databases, use of ORCiD by authors and information on the date of submission, acceptance and publication of originals. The results indicate that more than half of the scientific journals are multidisciplinary in nature and were created between 2012 and 2019; they are linked to Higher Education Institutions and are indexed in at least one database, with biannual publications. However, the study also shows that the majority have not published for at least a year. It is concluded that the profile of electronic scientific journals in Angola, reflects the country's academic and scientific context, with many challenges to be overcome in this area.

Jesus A. Tomé, Ph.D. ABSTRACT This study, which has as its problematic the repoliticization of the concepts of citizenship and peace and their joint analytical use, aims to show to what extent the national appropriation of the notions of “citizenship” and “peace” is conditioned by the international agenda, after the end of the civil war in Angola in 2002. This study is a qualitative approach, of a theoretical nature, developed through exploratory bibliographic research. The results indicate that, in Angola, the appropriation of the term “peace” is associated with the appropriation of the term “citizenship” only after the end of the civil war and, from an instrumental point of view, gains some importance following the birth of a new constitutional jurisdiction that changes several of the country's political rules and positions the citizen in an immense sphere of public spaces, but conditioned by the international agenda. From these results, we conclude that, in the postwar context, there are more continuities than ruptures in relation to the need for endogenous appropriation of the concepts of citizenship and peace and the deepening of the positioning of national and local actors within the dimension of the nation-state. * How to cite: Tomé, J.

Vivaz Bandeira, M.Sc. ABSTRACT Since the appearance of the Ombudsman in the Angolan legal system, through Article 142 of the Constitutional Law of 1992, and the election of the first Ombudsman in 2005, Angolans have had an independent administrative authority responsible for defending the fundamental rights and freedoms of citizens. The complaint to the Ombudsman represents an administrative guarantee for individuals to claim their rights and protect their legitimate interests in the face of an act or omission by the Public Administration that violates or threatens them. The aim of this article is to analyse trends in complaints to the Ombudsman, based on his activity reports for the years 2011, 2014, 2018 and 2022. This is an exploratory and documentary study, which analysed sociodemographic variables, the subject of the complaint, the institution targeted, and the solution given. The interpretative or hermeneutic method was also used in the interpretation of legislative texts. The results point to an increasing number of complaints to the Ombudsman, mostly made by citizens of Luanda, with a predominance of males, with the most targeted institutions being central state administration bodies and filing as the most recurrent solution. The conclusion is that there is an annual increase in the number of complaints, although this does not reflect the diversity of the more than thirty million inhabitants.

When not treated correctly, the infection causes dysfunction in other organs, leading to sepsis. Objective: to describe the use of antibiotics in the treatment of urinary tract infections in the population of the Canâmbua neighbourhood. Methodology: the qualitative and quantitative prospective descriptive methods were used. The sample was selected using the simple random sampling technique, with a sample of 204 individuals who admitted to using antibiotics at some point. Results: females predominated with a percentage of 72.6% and the predominant age group was 18-25 years old with 46.6%. As for occupation, most were students with 40.2%. High school graduates accounted for 43.1%. The most used antibiotics were amoxicillin (53.4%) followed by metronidazole (33.3%), and most of the sample (77.5%) had no adverse effects. Conclusions: The data show that most of the individuals took the treatment because of a doctor's prescription and experienced improvement with isc.uninjingambande.ed.ao Page 47 of 93 | Preprint Version the treatment taken between 3 and 7 days, which means that they complied with the doctor's instructions, even though other individuals practiced self-medication.

The choice of the topic was due to the poor knowledge found in the students of the 9th class of the application school ´´Cor Mariae´´ of Uíge on the topic mentioned above, as well as the consequences of the undue treatment that man through his activities has been giving this precious liquid day after day. The research was carried out following three stages: stage 1 – diagnosis, collection of primary data and the constitution of the theoretical framework, stage 2 – elaboration of the proposal for educational activities to overcome the weaknesses found in 9th grade students and stage 3 – application, analysis, and evaluation of the proposal. The general objective of the same was to propose educational activities that would help the students to understand that freshwater pollution has served as a vehicle for endemic diseases, as well as increasing cases of infant mortality. To achieve this, research methods divided into three categories were ISC.URNM 23: abstracts book Page 48 of 93 | Preprint Version used, including: theoretical, empirical, and statisticalmathematical methods. The results of the initial diagnosis were very poor, the number that responded best fluctuated at 24%, proving insufficient knowledge, the educational activities applied resulted in improved results after applying the final diagnosis, with 79% responding correctly, proving the improvement of knowledge and achievement of the proposed objective.

The experiment was carried out in randomized blocks with four treatments and 3 replications, totalling 12 treatments. isc.uninjingambande.ed.ao Page 49 of 93 | Preprint Version The treatments consisted of a McPhail trap with 100% mango juice, a McPhail trap with industrial juice 12 fruits, a pet bottle trap with 100% mango juice and a pet bottle trap with industrial juice 12 fruits. The distance between traps was 75 linear meters, occupying a total area of 6.75ha. The fruit flies were collected weekly from the traps, washed with running water, and preserved in tubes with 70% alcohol while the attractants of fresh mango juice and industrial fruit juice were replaced at the same frequency. The collected flies were counted and identified in the biology laboratory at Kimpa Vita University, and it was possible to identify, using an identification key, 3 species of fruit flies, namely Ceratitis capitata, Batrocera Carambolae, and Anastrefa fraterculus. Overall, 2065 fruit flies were captured, 47% being Ceratitis capitata, 44% Bactrocera carambolae and 9% Anastrepha fraterculus, respectively. An increase in the fruit fly population was observed, which reached its peak in February, coinciding with the reduction in rainfall, temperature, and the end of the mango production season. It is concluded that the period with the highest incidence of fruit flies in this agroecological zone was the month of February with the highest occurrence of the species Ceratitis capitata.

Delta type traps with sexual pheromone ISCAl and TUTA were randomly installed in tomato commercial fields in farms, namely, Catinda in Conda municipality, Quinta dos Pomares in Amboim municipality and “Boa Vontade” in Sumbe municipality. The study enabled to capture 16.146 insects, morphologically identified as Tuta absoluta, with an incidence considered regular below 50% in the assessment scale of 0 to 5, estimated at 48% in Catinda, 31% in Quinta dos Pomares and 43% in “Boa Vontade” farm. The capture of Tuta absoluta males caused a reproduction disequilibrium of this pest with subsequent reduction in the numbers of larvae that attack tomato culture in all stages of phenological development. Losses of tomato production were recorded as 48% in Catinda, 32% in Quinta dos Pomares and 65% in “Boa Vontade”. In the last farm production loss was not proportional to pest incidence. The usage of Delta type traps with sexual pheromones contributed to the reduction of the incidence of T. absoluta, which had the highest occurrence in the first half of December with average temperature of 25ºC and weak precipitation, being the recommended period for control measures.

ABSTRACT The tomato moth has been reported as one of the main causes of losses in tomato production. However, the effectiveness of plant extracts of Azadirachta indica, Ricinus communis and Nicotiana tabacum in controlling it in the tomato cultivation among farmers in Luanda is still unknown. The objective of this study was to evaluate the effectiveness of the plant extracts of neem, castor, and tobacco in controlling caterpillars in tomato plants, with a view to offering farmers an alternative to chemical control. The experimental design was randomized blocks, with four treatments and four replications, the average number of damages on the leaves when compared before and after the applications, showed statistically ISC.URNM 23: abstracts book Page 58 of 93 | Preprint Version significant differences between the treatments, with the control showing a higher number of damages on the leaves. The incidence of tomato fruits after applications shows that there are significant statistical differences, and in the first application 38 days after planting, was observed that the control treatment had a higher incidence than the other treatments followed by neem and with the lower numbers than tobacco and castor beans, which showed excellent performance in this application. In the second spraying at 43 days, it was found that the control continues to have high percentage of incidence among treatments, followed by tobacco, castor beans and finally neem, which showed the lowest incidence, after the third application at 50 days, it was verified that, although the control presents an even higher incidence followed by tobacco and castor bean, neem presents a lower percentage of attack, on the other hand in the fourth spraying after 60 days, the biopesticides castor bean, tobacco and neem showed similar averages of incidence and the control continuing with greater incidence. However, neem, castor and tobacco extracts performed well in controlling Tuta Absoluta, significantly reducing damage caused by this pest to tomato fruits.

Survey of plant species (herbaceous, creeping, climbing, shrubby and arboreal) located in residential and administrative backyards; in schools, on the streets, in squares and in the urban area of the city of Uíge, it was carried out between October 2022 and August 2023. To this end, the quadrant point method was carried out with four plots of 10 x 10m. 364 species of vascular plants belonging to 227 genera and 74 botanical families were documented. Among the 364 species listed, 161 are indigenous and the remaining 203 are exotic - introduced voluntarily or involuntarily. According to the urban population of Uíge, 69.16% of plants in the urban area participate mainly in CO2 sequestration, 9.33% in medicinal treatment, 5.33% in human nutrition and 3.73% in ornamentation. Furthermore, 1.69% of local biodiversity serves as forage for animals, 1.33% for bioenergy, 1.24% as windbreak, and 1.2% used as shade.

The development and increase in vegetables production is intrinsically linked to fertilization as a source of nutritional supply to plants. The current study conducted at the Polytechnic Institute of Cuanza-Sul in 2023 was funded by PDCT program and had the objective to determine the influence of inorganic fertilization in the production of Amaranthus viridis. Four-week-old seedlings were transplanted into 30-cm diameter plastic pots, filled with local soil, and arranged in a completely randomized design with 5 repetitions, where applied NPK 12-24-12 treatments doses consisted of 0, 2, 4, 6 and 8 grams. Two months later transplanting the seedlings, the experiment was ended, and the collected agronomic data was submitted to analysis of variance through Statistics 8.0 program. Applied treatments were statistically significant (p?0.05), showing a strong relationship among inorganic fertilization and improvement in plant height, root length, stem diameter, chlorophyl content, root mass and yield in the order of 90%, 82%, 99%, 95%, 99% and 99%, respectively. The study allowed to determine inorganic fertilization as having significant influence in the increase of Amaranthus viridis production, as observed in similar studies with Amaranthus blitum and caudatus. Doses of NPK 12-24-12 above 6 grams are of concern, since the model revealed a negative influence in the agronomic aspects analysed.

Total soluble solids, total titratable acidity and ethanol levels were also analysed. As a result, the microbial populations observed were 7.9 log CFU.ml-1 (Malanje), 8.3 log CFU.ml-1 (Huambo) for the total flora; 7.8 log UFC.ml-1 (Malanje) and 8.5 log UFC.ml1 (Huambo) for lactic acid bacteria and 5.1 log UFC.ml-1 (Malanje) and 5.8 log UFC.ml1 (Huambo) for enteric bacteria. A final pH of 3.9 (Malanje), 4.3 (Huambo) and 3.6 (Bié) was observed after 24 hours; total soluble solids of 3.9 ºBrix (Malanje), 1.6 ºBrix (Huambo) were found. After the fermentation period to which Kissangua was subjected, the growth of lactic acid bacteria was observed, which allowed the reduction of enteric bacteria, resulting from the production of metabolites such as lactic acid and due to the reduction in the pH of Best Poster Award isc.uninjingambande.ed.ao Page 63 of 93 | Preprint Version the medium, reaching the minimum levels of health safety of the product.

The lack of scientific information and technical bulletins motivated the carrying out of this work, which aims to create effective methods for controlling and reducing damage caused by this pest. The present study had the technical support of the UN/FAO and was carried out from February to May 2023 on two farms in the town of Capanga in Amboim, with the aim of evaluating the incidence of armyworm fall (Spodoptera frugiperda) through monitoring in the crop of corn (Zea-mays). The experimental design was completely randomized with two treatments, namely Delta type traps with biological and sexual pheromone attractant (Spodoptera frugiperda PH-869-1PR), food attractant made with corn grains, table banana pulp and Pet type with the same attractions. The traps were installed with the support of a stake at a height of 1.5 m from the soil surface after ISC.URNM 23: abstracts book Page 64 of 93 | Preprint Version sowing the triple hybrid corn called Pampa. The data collected were subjected to analysis of variance using the Sisvar 5.7 program. The incidence was assessed by capturing 477 moths on two farms, 48.6% on Hali-Ipua and 51.4% on the José Domingos farm. The use of natural extracts was 50% efficient to monitor adults of Spodoptera frugiperda. The incidence was highest in March and April, coinciding with the favourable climate in terms of temperature and precipitation, and the study allowed us to observe that both treatments contributed to reducing damage to the corn crop.

ABSTRACT Loengo (Anisophyllea boehmii Engl.) is a fruit from the Miombo forest, widely used by the rural Angolan population mainly as food, but little scientific knowledge has been produced around this fruit regarding its food potential. The present work aims to study the technological, nutritional, and sensorial potential of loengo. A survey aimed at obtaining information on the socio-economic potential (agronomic characterization, location, and marketing) was conducted in locations in isc.uninjingambande.ed.ao Page 65 of 93 | Preprint Version the provinces of Malanje, Huambo, Benguela and Huíla. The nutritional composition (dry matter, TSS, AT, pH, proteins, lipids, sugars, organic acids, insoluble dietary fibre and mineral salts) were also studied using classical methods and through High Performance Liquid Chromatography (HPLC), the polyphenols and carotenoids were analysed by HPLC using C18 and C30 columns respectively and the aromatic compounds were extracted by Solid Phase Micro-extraction and analysed by Gas Chromatography coupled to Mass Spectrometry. The results of the surveys showed that 79.2% are women, all respondents do not know how much they consume per month and are generally interested in processed products. As for dry matter contents, they ranged from 24.71 (0.51) in Mixture to 20.24 (0.19) g.100 g-1 in Huíla; NDF fibres (g.100 g-1 MS) from 20.99 (0.31) for Mixture to 15.48 (0.17) for Malanje; the most predominant sugar is fructose with levels (g.100 g-1 MS) of 15.98 (0.40) for Malanje to 14.93 (0.64) for Huambo. the fruit is rich in minerals mainly potassium, calcium, magnesium, and aluminium and in bioactive compounds such as polyphenols with 2303.04 mg Eq AG.100 g-1 MS for the Huíla fruit and carotenoids with a maximum content of 24.90 mg Eq B-C .100 g-1 MS in Huambo. The fruits presented 22 different aromatic compounds where the concentrations are quite variable.

Malanje-Angola | *Corresponding author: [email protected]. https://orcid.org/0009-0007-1075-6599 ISC.URNM 23: abstracts book Page 66 of 93 | Preprint Version ABSTRACT Kissangua is a drink fermented from corn flour, consumed throughout the country. This product is generally family produced and is sometimes sold without considering aspects linked to food safety or even from an aesthetic point of view, given the type of packaging used. Despite the high appreciation, production and consumption conditions remain traditional and little studied. The objective of this study is to understand the socioeconomic aspects involved in the production of kissangua in the provinces of Bié, Huambo and Malanje. To achieve this objective, a survey was carried out in the host municipalities of the provinces under study, as they are considered areas of high production and consumption of this drink. The results obtained in this research showed that the production and concomitant commercialization of kissangua is an activity carried out exclusively by women, that is, 100% in the case of Bié, 97.14% in Huambo and 94.29% in Malanje. This work made it possible to identify four drink production technologies, one in the province of Huambo, two in the province of Bié, one of them is the same as the one identified in Huambo and two in the province of Malanje. The acceptance criteria for kissangua in Huambo are related, among others, to the sweet flavour and the presence of coarse flour, in Bié it has to do with the sweet taste, presence of coarse flour, fermented aroma and acidity and for Malanje, consumers associated it with global appreciation of the sweet flavour, presence of bran and with coarse flour. Keywords: Kissangua, spontaneous fermentation, microbial flora, physical-chemical characteristics isc.uninjingambande.ed.ao Page 73 of 93 | Preprint Version of these codes was clearly bar codes. A comprehensive analysis was conducted to grasp the authors' perspectives on the subject matter. The theoretical foundation was made to understand the authors' thoughts on the topic. Therefore, the following starting question was raised: To what extent are barcodes useful in managing the bibliographic collection? The general objective was to understand the advantages of using barcodes in library management. This research used a descriptive methodology with a qualitative-quantitative approach. The data collection techniques are interviews and questionnaires for employees and users by filling out a script and form respectively, and the semi-structured observation technique to note and describe the observed phenomena. The results of the questionnaires and interviews showed that barcodes are extremely useful in managing library inventory, allowing staff to identify each item easily and effectively in the collection differently. It showed that they are great because they simplify the loan, return and inventory processes, making it easier for employees to save time and effort.

PREVENTIVE HEALTH, WELL-BEING, AND FOOD SECURITY Human pathogenic vibrio species in African Agrestic Communities: South-Western Uganda and Eastern Cape of South Africa in Perspective. Uchechukwu Nwodo, Ph.D. [email protected].za ABSTRACT Background: The global trend of disease emergence has been exacerbated by multiple factors including climate change, and environmental distress syndromes. Thus, pathogens acquire new traits which may constitute a public health burden in the near or distant future. Although viruses have been leading the charge on the recent pandemic scale of disease burden, antimicrobial resistance is trailing behind and may constitute the next global pandemic. Resistance to antibacterial agents has been consequent to overuse, misuse, and underuse of antibiotics. However, the role climate change and its resulting effects including environmental distress syndrome play in disease and antimicrobial resistance emergence are not clearly understood. Therefore, an account of a decade of research on human pathogenic Vibrio species in South-Western Uganda and the Eastern Cape of South Africa will be the bane of the keynote. isc.uninjingambande.ed.ao Page 77 of 93 | Preprint Version Method: Hospital drains, and municipal treatment plant wastewaters, and the stagnant, flowing, and underground freshwaters were routinely sampled and processed using a standard membrane filter procedure and analysed using the culture-dependent technique. The isolates were identified using the polymerase chain reaction, and an antibiogram was done using the standard disk diffusion technique of Kirby–Bauer as approved by CLSI 2018 guidelines. The elucidation of antibiotic resistance genes and virulence signatures was achieved by molecular technique targeting specific regions of the isolates. Findings: The decade studies reported Vibrio species across the districts of SouthWestern Uganda and the municipalities in the Eastern Cape Province of South Africa where the studies were conducted. Varying degree of antimicrobial resistance was recorded against the following antimicrobial agents: colistin (polymyxin), cefotaxime, azithromycin, fluoroquinolones, and carbapenem. Complete multiple antibiotic resistance phenotypes ([M]ARPs) to antibiotics (A-CTX-CXM-MEM-ATH-K-TM-CPB-NI-CIP-NA) were also recorded with some isolates, which produced multiple antibiotic resistance indexes of 1. Thus, suggesting a high risk to public health. The chromosomal and plasmidencoded antibiotic resistance genes including AmpC beta-lactamases were found in varying proportions among the isolates from both African countries. In the same vein, dihydropteroate synthase type-1 and 11 genes were detected in some isolates from the study sites over time. The genes encoding cholera toxin (CTX-phi), one of the principal virulence factors of the diarrheal pathogen; Vibrio cholerae, were detected in the Vibrio cholerae isolated from the surface waters of the study sites. Other virulence determinants harboured by some Vibrio cholerae isolates include RS 1, RTX cluster, HLY-A cluster, ctxB, cep, and ace toxigenic genes were ISC.URNM 23: abstracts book Page 78 of 93 | Preprint Version detected among Vibrio cholerae isolates. The rstR region of the Classical and El Tor biotypes was present in some isolates, and that revealed the presence of various genes of emerging relevance. The presence of El Tor and the Classical hemolysin gene in some of the isolates recovered from the agrestic communities also indicates the occurrence of emerging and unusual genotypes among the strains. Conclusion: The human pathogenic Vibrio species are emerging with novel virulence and antimicrobial resistance traits. Consequently, the continuous monitoring of the human pathogenic Vibrio species in the environment particularly, the puddle for high microbial interactions and genetic recombination that leads to the emergence of novel traits in the pathogens, is imperative. Conclusively, vigilance through surveillance and preparedness through the development of novel approaches to combat the scourge of resistance to known antibiotics and emerging virulence factors will be the most desired approach for a safeguard against the impending but sure-to-occur scourge of the emergence of novel traits in human pathogenic Vibrio species.

Challenges of Agri-food Processing Industry in South Africa. Maboko Samuel Mphosi, Ph.D. ABSTRACT Agri-processing industries in the South African economy constitute a diverse set of industries ranging from the ISC.URNM 23: abstracts book Page 80 of 93 | Preprint Version simple processing of food and other agricultural products to more sophisticated manufacturing activities such as processing cotton, leather, timber and rubber into finished products and furniture manufacturing. Agriprocessing creates enhanced agricultural productivity and increased farm household incomes, promotes yearround availability of affordable, safe, and nutritious food, and creates jobs. Most labour-intensive agri-processing industries are experiencing declining or stagnating output, investment and, most importantly, employment in South Africa. Identifying and promoting the growth of high-value-added activities in the sector can assist in realising the potential of agri-processing industries in the country. Coordinated implementation of policy strategies to revive the dynamism in labour-intensive industries is needed to exploit the sector’s potential.

Mashilo M. Matotoka*, Ph.D.; Peter Masoko, Ph.D University of Limpopo, Department of Biodiversity, Private Bag X1106, Sovenga, 0727 (Arial, 8, center) | * [email protected] ABSTRACT ISC.URNM 23: abstracts book Page 82 of 93 | Preprint Version Myrothamnus flabellifolius is a medicinal plant generally found in southern Africa and used in traditional medicine to treat infectious diseases, respiratory, inflammation, and kidney ailments. The focus of this study was to investigate the effect of fractionation on the anti-bacterial, and antibiofilm activities of the leaves and stems of M. flabellifolius on Klebsiella pneumoniae, Escherichia coli and Pseudomonas aeruginosa. Plant material was simultaneously extracted using n-hexane and 70% acidified acetone. Liquid-liquid extraction was used to fractionate the 70% crude acetone extract. Total phenolic and terpenoid contents were quantified and LC-MS/MS used to identify bioactive compounds. Antibacterial activity was determined using bioautography, broth micro-dilution and growth curve assays. Biofilm inhibition assays were evaluated using the crystal violet assay. The ethyl acetate and butanol subfractions of the stem and leaves had the highest concentration of phenolic and terpenoid contents and subsequently, the ethyl acetate subfractions had the highest anti-bacterial activity in the broth micro-dilution assay with average minimum inhibitory concentrations (MIC) of 0.235 mg/mL against tested pathogens. LC-MS/MS identified several bioactive phenolic acids. The growth curves of P. aeruginosa and E. coli suggested that ethyl acetate subfractions suppress growth by lengthening the lag phase. In contrast, only the hexane and dichloromethane extracts of both plant parts demonstrated notable inhibition of irreversible cell attachment and eradication of mature biofilms of E. coli and K. pneumoniae (lowest inhibition> 65%). The results from this study suggest that biofilm inhibitors from M. flabellifolius against the test pathogens are found in the non-polar extracts while antibacterial activity against planktonic cells is possessed by the intermediate and polar subfractions.
