Disappearance and prevalence of extended-spectrum β-lactamase–producing Escherichia coli and other coliforms in the wastewater treatment process
2023
Overview
Antibiotic-resistant bacteria (ARBs) can now be detected not only in clinical institutions but also in wastewater treatment plants (WWTPs), extending the range of emergence to residential areas. In this study, we investigated the change of antibiotic-resistant
Escherichia coli
(
E. coli
) and other coliforms in each treatment process at WWTPs. Throughout the treatment process, the numbers of
E. coli
and other coliforms were significantly reduced to less than 5.7 ± 0.5 CFU/100 ml and 2.4 ± 0.0×10
2
CFU/100 ml, respectively. However, ESBL-producing
E. coli
and other coliforms were detected in each treatment process (even after chlorination) at 5.6% and 4.8%, compared to the total
E. coli
and other coliforms counts. Then, ESBL-producing-related genes were identified via PCR analyses, and the most predominant gene was CTX-M-9 in both
E. coli
(47.2%) and other coliforms (47.3%). Although actual WWTPs greatly reduced the number of bacteria, the relative prevalence of ESBL-producing bacteria was increased, suggesting that ESBL-producing bacteria remain in the effluent at minimal concentrations and could be diffusing to water bodies.
