For the determination of the MBC, this technique is used coupled with spreading on agar medium. <strong>Results: </strong>The results show an antibacterial activity of the extract with MICs between 0.625 - 5 mg/ml. The CMB of <i>Enterococcus faecalis</i> ATCC 29212 is 2.5 mg/ml while that of Methicillin-resistant <i>Staphylococcus aureus</i> and <i>Staphylococcus epidermidis</i> CIP 8039 is 5 mg/ml. The reversion of bacterial resistance has shown a synergy of action between our extract and conventional antibiotics.展开更多

In the coastal regions, fish farming is practiced on the outskirts of market gardening sites. However, poorly regulated cultivation practices and increasing pollution do not necessarily guarantee the sanitary quality of the products delivered. This study aims to evaluate the physico-chemical qualities of the water used for watering and, secondly, the lead and cadmium contamination of the water used for watering, the soil (sediment) and the fish products (fish) on the urban market gardening perimeter in the commune of Lokossa in Benin. These various samples taken for this purpose were analysed at the Ministry of Health’s Water and Food Quality Control Laboratory. We noted pollution of organic elements through the physico-chemical parameters measured such as temperature, NTK, COD, BOD and total phosphorus and confirmed by average lead and cadmium levels of 0.42 mg/L in water, 0.52 mg/L in sediment and 0.31 mg/L to 0.76 mg/L in fish tissue (Carp and Catfish) for lead and 0.07 mg/L in water, 0.1 mg/L in sediment and 0.5 mg/L in fish for cadmium. These rates are well above the normal values accepted by the GESAMP, PNEC INERIS and FAO standards. The consequences of this contamination are health risks for consumers.展开更多
