|
Fecal samples from feral hogs were collected (n=36 ) from four locations in Texas
including Runnels , Haskell , Crane , and Sutton counties . Samples were analyzed for Escherichia
coli populations , Salmonella spp . and Listeria spp . prevalence , and bacterial isolates were
collected . Commercial microbroth dilution plates were used to establish antibiotic resistant
profiles on the isolates . Non‐type specific E . coli was found in 91 .7 % of total samples (n=36 )
with isolates exhibiting the most common resistance (n=132 isolates ) to Sulfisoxazole (46 .2 % ) ,
Tetracycline (2 .2 % ) , and Nalicixic acid (2 .5 % ) . Salmonella spp . was found in 27 .7 % of total
samples with isolates (n=37 ) showing the most common resistance to Sulfisoxazole (29 .7 % ) and
Cefoxitin (2 .7 % ) . Listeria spp . was found in 22 .2 % of total samples with isolates (n=29 )
exhibiting the most common resistance to Lincomycin (89 .6 % ) , Daptomycin (68 .9 % ) , and
Streptomycin (44 .8 % ) . This study provides evidence that feral hogs do harbor resistant
pathogens that could be foodborne given the right opportunity .
