Commensal faecal Escherichia coli of porcine origin are potential carriers of antimicrobial resistance genes (ARGs) and virulence associated genes (VAGs). The use of animal faeces as manure is a common practice that contributes to the spread of multiple drug resistant (MDR) bacteria. Here we investigated the extent of the presence of ARGs and VAGs in 117 intI1+ commensal E. coli isolated from faeces of healthy sows and their offspring in 2017, sourced from a commercial production operation in Australia. Dark pink, lactose-fermenting colonies on MacConkey agar were tested by PCR for the presence of uspA, an E. coli specific marker, and the class 1 integrase gene intI1, an indicator of the presence of multiple-drug resistance1. intI1+ E. coli was detected in more than two thirds of sows and piglets when only three colonies from each faecal sample were tested by PCR. The intI1 carriage rate among sows increased when a further 10 colonies were screened in the negative faecal samples, suggesting that most animals shed intI1+E. coli. These results are consistent with an earlier study of intI1+E. coli sourced from two unrelated commercial swine production operations in 20072. Whole genome sequencing analysis showed that most isolates had a MDR profile and belonged to phylogroups A and B1. ST10 and ST20 were the most prevalent sequence types (STs). Resistance to b-lactams, aminoglycosides, trimethoprim, macrolides, sulphonamides, tetracyclines, and heavy-metals was prevalent. Resistance to last-line agents (e.g. polymyxins) was not encountered. IS26, an insertion element involved in the capture and mobilisation of ARGs, was present in 92% (108/117) of isolates. The results of this study suggest that antimicrobial stewardship has played a role in preventing the spread of ARGs encoding resistance to clinically relevant antibiotics among commensal faecal E. coli sourced from Australian pigs.
