Staphylococcus spp. have become important human pathogens in recent decades due to the selection of resistant bacteria and the spread of their resistance genes in the environment. This study aimed to evaluate the resistance of Staphylococcus spp. obtained from sewage in the city of Manaus, Amazonas state, Brazil. The isolates were tested for susceptibility to antimicrobials using the Kirby-Bauer method for ampicillin, azithromycin, ciprofloxacin, clindamycin, chloramphenicol, erythromycin, gentamicin, oxacillin, cefoxitin, linezolid, penicillin, rifampicin, sulfazotrim, tetracycline and vancomycin. Among the strains isolated from sewage, the greatest resistance was observed for penicillin and oxacillin, with 100% of isolates resistant to these antibiotics. Some antibiotics had resistant and sensitive strains (ampicillin, clindamycin, erythromycin, cefoxitin, azithromycin). Staphylococcus spp. were identified as sensitive to ciprofloxacin chloramphenicol gentamicin linezolid sulfazotrim tetracycline, vancomycin, with no strain resistant to these antibiotics.
