Prevalence of a carbapenem-resistance gene (KPC), vancomycin-resistance genes (van A/B) and a methicillin-resistance gene (mecA) in hospital and municipal sewage in a southwestern province of Saudi Arabia

OBJECTIVE: According to the World Health Organization, the increasing antibiotic resistance of pathogens is one of the most important threats to human health. Prevalence of a carbapenem-resistance gene (KPC), vancomycin-resistance genes (van A/B) and a methicillin-resistance gene (mecA) in hospital and municipal sewages will be potential threat to public health. RESULTS: Vancomycin-resistance genes were detected in the sewage of community tank-II, sewage tank of the tertiary and general hospital. Carbapenem-resistance gene was detected in sewage of community tank-II and sewage from tertiary hospital. Methicillin-resistance gene was detected in sewage of community tank-II, sewage from a fish market sewage tank and sewage from an animal slaughter house sewage tank. The detection of a KPC, van A/B and a mecA in sewages will help further the process to take the appropriate measures to prevent the spread of such bacteria in the environment.
