| Summary: | <b>Aim: </b>This research was carried out to detect CPV and CCoV infections in
dogs in comparison with rapid kit and PCR and to determine the molecular
characterization of these infections in Konya region. Besides, it was aimed
to determine the sensitivity and specificity rates of the diagnostic tests after
fresh or freeze-thawed stool for infection diagnosis.<p>
<b>Materials and Methods: </b>Faecal samples were collected from 50 unvaccinated,
0-12 months old dogs with diarrhoea symptoms at the shelter. The samples
were analysed for CPV and CCoV by rapid test and PCR test. After freezethawing,
the samples were checked again with the same tests.<p>
<b>Results:</b> CPV was positively diagnosed by rapid test and PCR in 2 and 29 fresh
stool samples, respectively, and CCoV in 14 and 28 samples. CPV positive
samples did not change while CCoV was diagnosed as positive in 10 samples
and 28 samples by rapid test and PCR, respectively, after the freeze-thaw
procedure. Although there were no differences in the diagnosis of CPV, the
sensitivity of the rapid test in the diagnosis of CCoV decreased after the freezethaw
procedure. In addition, only CPV-2b type was detected in CPV positive
samples and both GI and GII subtypes were detected in CCoV positive samples
as molecular. In conclusion, it was observed that rapid tests are not sensitive
for accurate diagnosis of CPV and CCoV infections.<p>
<b>Conclusion:</b> The importance of choosing molecular diagnostic methods and
using fresh samples for accurate diagnosis of virological infections can be
emphasized. |
