A One Health Study on Antibiotic Resistance Profile and Biofilm-Forming Ability of E. coli and Non-Typhoidal Salmonella spp. from Dairy Cattle Farm Settings
Page No. : 72-77
ABSTRACT
The present study was envisaged to analyse a total of 164 samples (60 feed, 60 water, 44 hand wash) for the presence of E. coli and non-typhoidal Salmonella (NTS), by microbiological and molecular methods. Overall occurrence rates of 64.63%, 19.47% and 10.36% were observed for E. coli, Salmonella spp. and NTS, respectively. The antibiotic susceptibility testing confirmed that 21.69% of E. coli isolates were multidrug-resistant (MDR), with 19.81% being ESBL producers, among which the highest MDR isolates were recovered from trough water (28.8%), followed by feed (21.21%) and hand wash (10.71%). Among the NTS isolates, 20.41% showed MDR pattern, and 11.76% were ESBL producers. A moderate biofilm-forming ability was exhibited by MDR test strains of E. coli at 24 and 48 hrs when compared with MDR-NTS strain which revealed weak biofilm formers at 48 hrs.Keywords: Antimicrobial resistance, biofilm, dairy cattle farm, E. coli, non-typhoidal, Salmonella
