| description | Background. Antimicrobials used for the treatment and prevention of bacterial infections are mainly released nonmetabolized into the aquatic environment via wastewater. Sometimes, unused therapeutic drugs are released down the drains that could act as selective pressure for the development of resistance. The aim of this study was to assess the bacteriological profile of wastewater in health facilities and determine antibiotic susceptibility patterns of bacterial isolates. Methods. A cross-sectional study was conducted from October 1 to December 26, 2020, in health facility wastewater. A total of 128 samples were collected from health facilities for bacteriological analysis and antimicrobial susceptibility testing. Result. A total of 128 samples were processed, and 81 bacterial isolates were recovered. The most common bacterial isolates were S. aureus (16/81 (19.8%)) followed by Klebsiella spp. (15/81 (18.5%)), E. coli (13/81 (16%)), P. aeruginosa (10/81 (12.3%)), Enterobacter spp. (8/81 (9.9%)), Citrobacter spp. (7/81 (8.6%)), coagulase-negative Staphylococcus (5/81 (6.2%)), Salmonella spp. (5/81 (6.2%)), and Shigella spp. (2/81 (2.5%)). A majority of isolates were resistant to ampicillin (62/81 (76.5%)). Only few isolates were resistant to ciprofloxacin (11/81 (13.6%)), chloramphenicol (13/81 (16%)), and kanamycin (8/54 (14.8%)). A majority of bacterial isolates (57/81 (70.4%)) were multidrug resistant (MDR). Conclusion. Wastewater from the health facilities contains antibiotic-resistant including multidrug-resistant bacteria. Therefore, health facility wastewater should be treated by appropriate wastewater treatment before being released into the environment. |
