Occurrence of Shiga toxin-producing Escherichia coli carrying antimicrobial resistance genes in sheep on smallholdings in Bangladesh.

ABSTRACT:

Background

Shiga toxin-producing Escherichia coli (STEC) are zoonotic foodborne pathogens and a significant concern with the emergence of antibiotic resistance. Close human contact might have a higher chance of being transmitted to humans from sheep if the sheep population is a potential reservoir of antimicrobial-resistant STEC. Therefore, this study aimed to examine the sheep population in rural Bangladesh for antimicrobial-resistant STEC.

Methods

We screened 200 faecal samples collected from sheep in three Upazilas from the Chattogram district. Randomisation of sampling was not performed due to the smaller flock size (two to six animals per smallholding). Phenotypically positive E. coli isolates were examined for two Shiga toxin-producing genes - stx1 and stx2. PCR-positi
