Effect of water reservoirs types on the prevalence and antibiotic resistance profiles of isolated from bathroom water in hospitals.

This study was aimed to isolate and characterize antibiotic resistance profiles that isolated from bathroom water of five hospitals in Bandung, Indonesia, with different types of water reservoirs. Total of 25 water samples from bathrooms of five hospitals were collected and analyzed for the existence of colonies on the surface of MacConkey agar media using a streak plate method and identified using phenotypic identification and a series of biochemical tests. All isolates were tested against ceftazidime, piperacillin/tazobactam, ciprofloxacin, meropenem, and gentamicin containing in paper disc, using the agar diffusion method. Of all samples, the total number of isolates was less than that of non-. In hospitals that use permanent bathtubs, a greater total bacterial count was obtained than those using pails. From 110 isolates, 14.54% were multidrug resistance antibiotics. The majority of the resistant isolates were from hospital B with permanent bathtubs. Of 25 isolates from that hospital, isolates were resistant to ceftazidime (20%), piperacillin/tazobactam (4%), ciprofloxacin (20%), and gentamicin (20%). The multiple antibiotic resistance index value of isolates was 0.4-0.6. Thus, it can be concluded that the bathroom wáter in the hospital with permanent bathtubs were potential reservoirs of antibiotic-resistant .
