Contamination of drinking water from improved sources with antimicrobial resistant Escherichia coli
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 6
Abstract
In this study, the microbiological quality of household tap water samples from the piped distribution system of Iligan City was assessed for the presence of total coliforms and Escherichia coli. Based on microbial risk assessment specific for drinking water, 60 out of the 108 samples exceeded the value for gastrointestinal risk and of which 54 (90%) exceeded both international and Philippine drinking water guidelines of less than one colonyforming unit (CFU) of E. coli per 100 milliliters of water sample. Fifty-four isolates were cultured and each isolate was tested for susceptibility against four antibiotics namely ampicillin, chloramphenicol, gentamicin, and tetracycline. Thirty-three (61%) of the isolates have shown susceptibility to all four antibiotics. The isolates have also exhibited low resistance rates to these antimicrobials as none was non-susceptible to chloramphenicol, only five (9.2%) were gentamicin-resistant, and six (11.1%) were resistant towards each of ampicillin and tetracycline. The findings of this preliminary study increases awareness on the presence of antibiotic-resistant E. coli strains in the drinking water system of Iligan City. Although the definite impact of these resistant strains to human health is not yet fully established, it is important to conduct constant monitoring as ignorance to potential risks may result to unnecessary waterborne disease outbreaks.
