Survival and Antimicrobial Resistance of Salmonella enterica isolated from Bathrooms and Toilets following Salmonellosis in Some Homes in Ado-Ekiti.

The survival of Salmonella enterica in different sites of bathrooms and toilets in fifty (50) domestic homes in Ado-Ekiti was investigated. The total percentage isolate from toilets was 44%; the highest been from the bowl water (70%) while in the bathroom it was 26% the highest been from sink (44%). The antimicrobial drug susceptibility of forty-four (44) of the isolates against ten (10) different conventional antibiotics was tested. The highest resistance was observed in Nalidixic acid (82%) and Ciprofloxacin (70%). Eight (8) isolates from the bathrooms were resistant to Ampicillin, Chloramphenicol, Ciprofloxacin, Gentamicin, Nalidixic acid, Trimethoprin-sulfamethoxazole and Tetracycline. All isolates were susceptible to Cefotaxime and Cefepime; five (5) isolates from the toilets were intermediately susceptible to Cefepime (MIC 16^g/mL). Studies of Salmonella cases showed that the bacterium persisted in household bathrooms and toilets for several weeks after individuals had recovered from symptoms of salmonellosis.
