The study investigates the prevalence and antimicrobial resistance of the extraintestinal pathogenic Escherichia coli (ExPEC) ST131 strain in humans and dogs in Sri Lanka.
Researchers analyzed 215 ExPEC isolates, primarily from humans, finding that 61.8% were ST131, with notable resistance rates to important antibiotics, including carbapenems.
The findings highlight the need for a One Health approach to monitor antibiotic resistance and indicate significant resistance trends in ExPEC across different populations in Sri Lanka.
