Abstract
This study evaluated the occurrence of antibiotic-resistant bacteria, antibiotic-resistant genes, and metal concentration in Sri Lanka's Kelani River to understand the seasonal impact on their prevalence. Resistance to various antibiotics was measured using the Kirby-Bauer disc diffusion method. *Escherichia coli* prevalence showed seasonal variation, with higher resistance to older antibiotics (tetracycline and sulfamethoxazole) than newer ones. Antibiotic resistance genes were detected, and seasonal variations were observed, highlighting the influence of environmental conditions on the development and transmission of antibiotic resistance.
