The global increase in microbial infections is strongly linked to the widespread dissemination of antibiotic resistance genes in the environment, posing a serious challenge to public health. In the present study, surface water samples were collected from multiple locations along the Daya River near Bhubaneswar, including sites impacted by untreated municipal sewage discharge. The predominant bacterial isolate was identified as Acinetobacter baumannii-exhibited resistance to commonly used antibiotics such as ampicillin and ciprofloxacin. These findings highlight the urgent need for improved sewage treatment and waste management practices to prevent contamination of riverine systems and limit the spread of antibiotic-resistant bacteria.
