Antimicrobial resistance and virulence genes in Escherichia coli and enterococci from red foxes (Vulpes vulpes)
The aims of the study were to analyse the prevalence of antimicrobial resistance and the
mechanisms implicated, as well as the virulence factors, in faecal Escherichia coli and
Enterococcus spp. from red foxes. From 52 faecal samples, 22 E. coli (42.3%) and 50
enterococci (96.2%) isolates were recovered (one/sample). A high percentage of E. coli
isolates exhibited resistance to streptomycin, tetracycline, trimethoprim–sulfamethoxazole or
ampicillin (54–27%), and they harboured the aadA, tet (A) and/or tet (B), sul1 and bla TEM …
