Abstract :

Canine parvovirus (CPV-2) is an important disease with high relatively prevalence. In the present study, the ultrasonographic and radiographic findings of the gastro-intestinal tract were detected in dogs suffering from hemorrhagic and non-hemorrhagic diarrhea. Thirty dogs between 2 until 11 months of age (mean= 5.43 months) were examined with confirmed canine parvovirus enteritis by immunochromatography assay (ICA). The studied dogs were categorized into three groups and each group was divided into subgroups (less than 6 months) and (above 6 months). The mean of wall thickness of stomach, small intestine and colon were recorded 1.38, 2.14 and 0.9 mm for group A1 and 1.5, 1.96 and 0.84 mm for group A2 respectively. The above parameters were detected for groups B1, B2, C1 and C2. The mean of peristaltic contractions in small intestine of different groups A1, A2, B1, B2, C1 and C2 were recorded 1.6, 1.4, 2.18, 1.5, 2.1 and 2.4 respectively. The statistical analysis showed a significant difference between groups A and B with C group (p<0.05), but the difference was not significant between groups A with B (p>0.05). The obtained results showed that hemorrhagic diarrheas (parvovirus and non-parvovirus) can decrease the number of peristaltic contractions in small intestine. Changes in echogensity were seen as hyperechoic (6 out of 30; 20%) and hypoechoic (5 out of 30; 16.67%). Although none of the above changes are pathognomonic for canine parvovirus enteritis, but the above findings in combination with other signs can be highly helpful in the treatment process.
