Abstract :

Antimicrobial resistance (AMR) is an ongoing concern globally. The emergence of several MDR Escherichia coli strains has exposed a vulnerable side of the antimicrobials. In North–East India, swine is considered an important livestock economically; therefore, the objective of the present study was to investigate the occurrence of antimicrobial resistance in healthy swine. The antimicrobial resistant characteristics of 27 E.coli isolates from swine (healthy) were performed by disk diffusion test. The antibiotic resistance–susceptibility profiles were conducted for 14 antimicrobials representing 9 antimicrobial drug types. The isolates had high resistance to sulphafurazole(70.37%), ampicillin(55.55%) followed by neomycin(51.85%), streptomycin(51.85%) and tetracycline(40.74%). Of the 27 E coli isolates, 14(51.85%) revealed multi–antimicrobial resistance to more than three different antimicrobial types. These results indicate an alarming percentage prevalence of multi–antimicrobial resistant E.coli isolates. Hence, proper maintenance should be done for curbing further problems.
