摘要

Household wastewater is a source of pollution and can present health risks when discharged into the environment. Thus, samples of household wastewater from a few neighborhoods in Brazzaville were analyzed for microbiological quality. The various samples were cultured for isolation on solid media using conventional microbiological methods. The bacteria isolated were identified by the <i>Enterobacter</i> System gallery. Sensitivity tests were performed using the standard antibiotic susceptibility test by diffusion on Mueller Hinton medium. At the end of the analysis, 51 <i>Enterobacteriaceae</i> were isolated and identified. They included: 8 (15.68%) <i>Escherichia coli</i>, 8 (15.68%) <i>Salmonella spp.</i>, 8 (15.68%) <i>Shigella spp.</i>, 8 (15.68%) <i>Klebsiella spp.</i>, 5 (9.80%) <i>Enterobacter aerogenes</i>, 8 (15.68%) <i>Enterobacter cloacae</i>, 3 (5.90%) <i>Arizona spp.</i>, 3 (5.90%) <i>Proteus spp</i>. The results obtained show that the bacteria tested showed total resistance to the following antibiotics: amoxicillin, amoxicillin + clavulanic acid, cloxacillin and nalidixic acid. On the other hand, imipenem, cefuroxime, cefotaxime, cefftriazone and kanamycin were the most active antibiotics with low levels of resistance. The low resistance rates observed for imipenem, cefotaxime, cefuroxime and cefftriazone show that these antibiotics can be used for the treatment of infections caused by household wastewater bacteria.
