Foi investigada a ocorrência de exposição em 13
canÃdeos não domésticos de vida livre (cinco
graxains-do-campo - Pseudalopex gymnocercus e
oito graxains-do-mato - Cerdocyon thous) da
região sul do Brasil ao vÃrus da cinomose canina
(CDV), parvovÃrus canino (CPV) e coronavÃrus
canino (CCoV). Anticorpos contra o CDV foram
detectados em 38,5% (5/13) das amostras. Haviam
anticorpos anti-CDV em 60% (3/5) dos P.
gymnocercus e em 25% (2/8) dos C. thous. A
freqüência foi maior entre machos e adultos. Para
CPV, 11 canÃdeos (84,6%) apresentaram
anticorpos, 80% (4/5) eram da espécie P.
gymnocercus e 87,5% (7/8) eram C. thous. Não
houve diferença de positividade para o CPV entre
sexos e idades. Anticorpos contra o CCoV foram
detectados em 38,5% (5/13) das amostras, sendo
60% (3/5) de positividade entre os P. gymnocercus
e 25% (2/8) entre os C. thous. A freqüência de
anticorpos para CCoV foi maior entre os machos e
adultos. O estudo revelou que estes canÃdeos
foram expostos ao CDV, CPV e CCoV.
The exposure of 13 Brazilian free-ranging nondomestic canids (five pampas fox - Pseudalopex gymnocercus and
eight crab-eating fox -Cerdocyon thous) from Southern region of Brazil, to Canine distemper virus (CDV), canine
parvovirus (CPV) and Canine coronavirus (CCoV) was investigated. Antibodies against CDV were detected in
38.5% (5/13) of the samples. There were anti-CDV antibodies in 60% (3/5) of P. gymnocercus and in 25% (2/8) of
C. thous. The frequency was higher among the adults and males. Eleven canids (84.6%) presented antibodies
against CPV, 80% (4/5) were from P. gymnocercus and 87.5% (7/8) were from C. thous. There was no difference in
positivity rate against CPV between gender and age. Antibodies against CCoV were detected in 38.5% (5/13) of the
samples, with 60% (3/5) of positivity in P. gymnocercus and 25% (2/8) in C. thous. The frequency of antibodies
against CCoV was higher among the adults and males. The study showed that these canids were exposed to CDV,
CPV and CCoV.
