Resumo
The closeness beteween wild and domestic animals with humans may result in
common diseases involving these three groups, including zoonotic and
antropozoonotic diseases. The study of bacteria and disease that affects
animals is an important way to approach epidemiologic control and sanitary
vigilance, as we do not understand the roll of wild animals in transmitting
diseases among wild, exotic and domestic animals. The main objective of the
present study was to search the presence of Escherichia coli and Salmonella
sp. from rectal swabs of non-domesticated Suiformes in Commercial herds in
Goiás State. It was collected rectal swabs of 100 Sus scrofa scrofa, 60 T.
pecari and 30 P. tajacu, from different ages. The samples were used in order
to obtain the isolation, antimicrobial profile, hemolisin test for E. coli and
virulence and resistance gene presences in both bacteria. The serotyping was
performed with polyvalent anti-O serum and the virulence and resistance
gene deteccion by PCR technique. The results shown high rates of
antimicrobial resistance and virulence and resistance genes in analyzed
groups of E. coli. The isolation of Salmonella sp. occurred in one sample of S.
scrofa, with high rates of antimicrobial resistance also, but no resistance and
virulence genes were detected in this isolate. We must pay attention to the
possibility of horizontal gene transference of virulence factors and resistance
trough contaminated water and food, that may transform commensal bacteria
in possible pathogenic agents. It is conclude: that Salmonella sp. is not
commonly isolated from T. pecari and P. tajacu, showing low frequency of
isolation in S. scrofa in these conditions; and E. coli with multidrug resistance
patterns is isolated from S. scrofa, T. pecari and P. tajacu in commercial herds
from Goiás State.
