238 fecal samples from crows foraging on hospital wastes were analyzed for ESBL-producing Enterobacteriaceae. ESBL-producing crow isolates were characterized and compared with 31patient isolates. 59% of crows carried ESBL-producers. These included E. coli, K. pneumoniae, R. terrigena and E. cloacae harboring CTX-M-1, CTX-M-15, CTX-M-55, CTX-M-79, CTX-M-14 genes. Human isolates only carried CTX-M-15 gene. 2/3 of crow E. coli isolates and all human E. coli isolates were MDR. Crows and patients shared E.coli sequence types including epidemic E. coli O25b-ST131 clone. Scavenging behavior of crows at poorly managed hospital waste dumps made them into potential reservoirs of antibiotic resistance including ESBL.
