Antimicrobial resistance is a global emergency which needs one health approach to address. The present study was conducted to detect the prevalence of beta‐lactamase and biofilm‐producing Klebsiella strains in rectal swabs (n = 624) collected from healthy dogs, cats, sheep and goats reared as companion or household animals in India. The dogs and cats were frequently exposed to third‐ or fourth‐generation cephalosporins for therapy. The sheep and goats were occasionally exposed to antibiotics and had environmental exposure. Phenotypical ESBL (n = 93) and ACBL (n = 88)‐producing Klebsiella were isolated significantly more (P < 0·05) from companion animals than household animals. Majority of the Klebsiella possessed blaCTX‐M‐15. The sequences blaCTX‐M‐15.2, blaCTX‐M‐197 and blaCTX‐M‐225 are reported first time from the companion animals. All ACBL‐producing isolates possessed blaAmpC. The present study detected 65·8% of Klebsiella strains as biofilm producers possessing the studied biofilm associated genes. The isolates showed phenotypical resistance against chloramphenicol, tetracycline, doxycycline, co‐trimoxazole, ampicillin, cefotaxime/clavulanic acid. The present study showed that companion and household animals (dogs, cats, sheep, goats) may act as a carrier of ESBL/biofilm‐producing, multi‐drug resistant, high‐risk clonal lineage of Klebsiella.
