[ 1 ] - Distribution of Antibiotic Resistance Genes among the Phylogroups of Escherichia coli in Diarrheic Calves and Chickens Affected by Colibacillosis in Tehran, Iran

Antibiotic resistance occurs in the endogenous flora of exposed population in addition to pathogenic bacteria. This study was conducted to evaluate the distribution of antibiotic resistance genes among 63 isolates of Escherichia coli of Escherichia coli (E. coli) in diarrheic calves and poultry. According to the results, B1 and B2 were the most prevalent phylogroups of E. coli in calves and pou...
