RESUMEN

Objective To study the non-fastidous antibiotic-resistance bacteria pollution in tap water from a neighborhood in Tianjin.Methods Tap water samples were collected and bacteria were isolated by R2A agar,and 16S rRNA gene sequence for the identification of bacteria isolates was used.Antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method.Results Among the 39 non-fastidous bacteria isolates,the resistance rate of antibioticresistance bacteria was 79.49%,including Enterococcus,Staphylococcus,Acinetobacter and Pseudomonas.Some bacteria (28.21%) showed resistance against only one antibiotic.The others (51.28%) were multiple resistant bacteria.Trimethoprim/sulfamethoxazole resistance was most prevalent (53.85%),and sulfamethoxazole resistance was also widely distributed (28.21%).Conclusion Tap water from this neighborhood is heavily polluted by non-fastidous antibioticresistantance bacteria,which deserves more attention.
