Bacterial isolates harboring antibiotics and heavy-metal resistance genes co-existing with mobile genetic elements in natural aquatic water bodies.

ABSTRACT: The rise in antibiotic-resistant bacteria and contamination of water bodies is a serious issue that demands immense attention of scientific acumen. Here, we examined the pervasiveness of ESBL producing bacteria in Dal Lake and Wular Lake of Kashmir valley, India. Isolates were screened for antibiotic, heavy metal resistant elements, and their coexistence with mobile genetic elements. Out of two hundred one isolates screened, thirty-eight were found positive for ESBL production. Antibiotic profiling of ESBL positive isolates with 16 different drugs representing β-lactam or -non-β-lactam, exhibited multidrug resistance phenotype among 55% isolates. Molecular characterization revealed the occurrence of drug resistance determinants blaTEM, AmpC, qnrS, and heavy metal resistance genes (M
