Determination of antibiotic resistance pattern in Escherichia coli strains isolated from animal faeces in a farm house

Abstract

The present study aimed to evaluate the antibiotic resistance pattern of Escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. A total of 28 E. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of E. coli strains was determined by meansof disc diffusion assay. The resistance pattern determined for all strains was amoxicillin, streptomycin,cefepime, azteronam, amoxicillin/clavulanic acid, ciprofloxacin and ceftriaxone. About 50-75% of the strainswere reported as resistant to more than five antibiotics (multidrug-resistant). This might result in broadeningof the antibiotic resistance canvas among animals and from animals to human taking the animal foodproducts or living in close contact with them.
