Vegetables are very important sources of protein and minerals. Some of them even have medicinal properties recognized traditionally. Despite the large number of studies carried out on various vegetables and vegetable crops, very few have scientifically explored the usefulness of S. macrocarpon. This study identified the main groups of chemicals and mineral elements to explain any medicinal or nutritional value. It has also identified some toxic elements contained in this vegetable. Phytochemical screening was carried out on the leaves and fruits of S. macrocarpon. Some mineral elements were determined by Atomic Absorption Spectrophotometry (sodium, potassium, calcium, magnesium) while protein, phosphorous, iron, copper, zinc and toxic metals (lead, cadmium) were determined by Molecular Absorption Spectrophotometry. Fat, ash, moisture and vitamins were sought. The study showed that the leaves of S. macrocarpon were more nutritious than fruits (P macrocarpon require that the consumption of vegetables should be as varied as possible and that the fruit may be consumed with caution. In addition, constraints about vegetable cultivation in Cotonou could lead to research findings that could help provide techniques for producing healthy *** A and K1 were found in both parts of this vegetable very rich in water while vitamin E has not been detected. S. macrocarpon also contains lipids at various levels.

Malaria is a parasitic disease caused by the bite of female Anopheles mosquito and particularly affects the tropical areas of the world. According to national statistics it is the leading cause of consultations and hospitalizations. Nowadays, despite the surveillance systems for efficient malaria control and access to generic drugs, Benin is witnessing an increased development of illicit drug markets with a large part of the population going towards such markets. However, this is not without adverse impact on the health of individuals, as well as, the economic status of the country. Therefore, the situation needs to be seriously considered by policy makers at various levels, health professionals but also the entire international community in order to thwart this *** the aforementioned situation, the current study was undertaken aiming to perform a quality control of selected antimalarial drugs of the illegal market in Porto-Novo city. Therefore, 40 antimalarial batches were randomly collected in the illicit drug market and submitted to analytical tests such as: macroscopic examination (a visual and critical examination);mass uniformity test;disintegration test;identification test and active ingredients’ content measurement. At the end of the study, the percentages of non-compliance is 97.5%, 5%, 15% and 27.5%, respectively for the content uniformity tests, disintegration, identification and assay. Over-all, 42.5% of noncompliance was recorded. The findings of this study prove that street vended drugs offer no guarantee of good quality and pose a threat to the health of populations. Also, the rate of non-compliance denotes a flaw in the security of the drug distribution system.

The objective of this study is to assess the quality of the artesian borehole water consumed by the population of the village of Dogbo Ahomey in order to prevent pathologies on the populations. Methodology and Results: The household surveys were supplemented by a campaign to analyze the water samples in the laboratory. The samples were analyzed according to the standardized methods of the American Public Health Association (APHAAWWA-WPCF, 1994). A total of twenty (20) physico-chemical parameters and four (04) microbiological parameters were used to assess the quality of the different water samples. The results of the physico-chemical analysis showed that the water samples studied present values that are below the standards recommended by the WHO and by the Beninese standards for the quality of drinking water (Standards, 2001). From a microbiological analysis point of view, of the four samples studied, two show strong pollution by germs. This could be a significant health risk for households who take water from these sources to meet their needs.

Cholera is a disease that Benin has been fighting against for years but which continues to create economic losses for households. The aim of this study is to assess the level of knowledge of the population about this disease and to assess hygiene practices in order to identify the factors responsible for its sustainability. The data were collected through a survey of 720 households in the 12 departments of the country. These data were analyzed with SAS software and three groups of people were identified on the basis of hygiene measures. The majority of respondents know cholera. The main symptoms they mentioned were vomiting (84.83%) and diarrhea (81.04%). Diarrhea was more reported in group 3 (88.96%) than in groups 1 (86.58%) and 2 (83.19%). Low levels of hygiene were the main cause of this disease. In the absence of toilets, the interviewees pass stool in the bush and at the edge of water sources used in households. Some of them have bins (in particular group 1) for household waste but do not subscribe to refuse collection structures. Therefore, they throw garbage in sometimes unofficial landfills. Others, on the other hand, have not garbage cans (mainly group 2) and they empty garbage everywhere (street, gutters and bushes). In addition, hand washing is hardly ever done after using the toilet. Hygiene practices in some households are insufficient, which does not protect the population from cholera.

Cholera is re-emerging as an infectious disease with an increase in its overall incidence in Africa since 2008. To analyze the epidemiological aspects of the cholera outbreak in endemic areas in Benin. The study is a retrospective investigation on 2560 data of cholera patients received in health facilities from 2012 to 2016 in Benin. Besides, a prospective study was conducted. This prospective study includes 513 person (health professionals, community workers and people exposed to cholera) of five different areas of the country. It was conducted from April 10 to May 10, 2017. A survey was conducted over 513 in order to collect data on cholera symptoms, hygiene guidelines suggested by the respondents, excreta disposal, drinking water, household waste management and direct observation. Software R 3.4.0 was used for simple correspondence factor analysis (CFA). From 2012 to 2016, 16.48% of samples were taken and 48.34% were positive for Vibrio cholera O1, El Tor biotype, Ogawa serotypes. The Littoral area is leading in the number of cases (33.83%) followed by Atlantic (23.75%), Ouémé (16.79%) and Colline (8.91%). The survey revealed that the exposed populations are unaware of the symptoms of cholera and do not perceive the quality of drinking water as a strong guidance in the prevention of cholera. Nevertheless, the majority of respondents (86%) are aware for the best times to wash their hands and know that they need to go to hospital in case of symptoms. Our study highlights the persistence of vulnerability factors to cholera in the targeted population, despite a good knowledge of prevention rules among staff and the population.

Recent ethnopharmacological data cited Senna siamea as one of the most widely used medicinal plants in the management of salmonellosis in Benin. However, data related to its activity on non-typhoidal Salmonella spp are limited. This study aimed to assess the antibacterial activity of Senna siamea on multidrug-resistant Salmonella. Ethanolic and aqueous extracts of S. siamea were tested for their antibacterial activity on four multidrug-resistant Salmonella: Salmonella Typhimurium ATCC 14028 and three Salmonella spp. isolated from animals intended for human consumption in Benin. Well diffusion technique combined with the determination by microdilution of Minimum Bactericidal Concentration (MBC) and Minimum Inhibitory Concentration (MIC) were used for antibacterial testing. From antibacterial testing, inhibition diameters of the extracts ranged from 7 to 11 mm, for the susceptible strains. Colistin (reference antibiotic) was active on all
