Heavy metals are dangerous pollutants for ecosystems, especially aquatic ecosystems, because of their concentration in certain living organisms and their presence in the food chain. This study aims to evaluate the bacteriological, metallic (Pb, Cd, As) and toxicological risks associated with houin logbo (toho lake) in the municipality of Lokossa. The results obtained concern everyone: Toho lake is contaminated by <em>Escherichia coli </em>and<em> faecal enterococci</em>, concerning the evaluation of the metallic contamination we have: water (Pb: 0.1032, Cd: 0. 046, As: 0);sediment (Pb: 14.79, Cd: 1.27, As: 0.800);<em>Oreochromis niloticus </em>(Pb: 0.143, Cd: 0.087, As: 0.466);soils (Pb: 8.528, Cd: 2.755, As: 0.833);<em>Solanum lycopersicum</em> (Pb: 0.098, Cd: 0.066, As: 0). Consumption of lake fish (<em>Oreochromis niloticus</em>) and market garden produce (<em>Solanum lycopersicum</em>) exposes populations, especially children, to the risk of As and Cd poisoning. 展开更多

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
