Overview
Antimicrobial resistance, virulence factors and genetic diversity of Escherichia coli isolates from household water supply in Dhaka, Bangladesh.
The study identified several AMR genes in E. coli isolates from household water in Dhaka, including bla CTX-M-15, bla CTX-M-1-group, bla TEM, bla OXA-1-group, bla OXA-47, qnrS, qnrB, and bla CMY-2. These genes conferred resistance to multiple antibiotics, highlighting the presence of multidrug-resistant E. coli in the water supply.
A Pilot Study of Chicago Waterways as Reservoirs of Multidrug-Resistant Enterobacteriaceae (MDR-Ent) in a High-Risk Region for Community-Acquired MDR-Ent Infection in Children.
The study identified various multidrug-resistant Enterobacteriaceae (MDR-Ent) in Chicago waterways, including genes encoding beta-lactamases (CTX-M-1, CTX-M-9, SHV-ESBL, CMY-II-AmpC), aminoglycoside modifying enzymes (aac-6'-Ib), quinolone resistance proteins (qnrB), efflux pump components (oqxA/B), and colistin resistance (mcr-1). These genes were found in E. coli, K. pneumoniae, and E. cloacae isolates and conferred resistance to multiple antibiotics.
The Impact of Chlorine Disinfection of Hospital Wastewater on Clonal Similarity and ESBL-Production in Selected Bacteria of the Family Enterobacteriaceae.
Chlorine-based disinfection promotes the survival of ESBL-producing bacteria and/or the transmission of genetic determinants of AMR, increasing the proportion of ESBL-producing Enterobacteriaceae in disinfected wastewater.
