              Abstract 
 Aim:
              The aim of this study was to screen the suspected samples by 
              polymerase chain reaction (PCR) and epidemiological analysis of 
              positive cases of canine parvovirus type2. 
              Materials and Methods: Fecal samples were collected from dogs 
              suspected for canine parvovirus type 2 (CPV-2) and viral DNA was 
              extracted. Primers were designed, and PCR was done with all 
              extracted DNA samples. Age, sex and breed wise distribution of 
              positive cases were analyzed. 
              Results: Out of a total 44 collected fecal samples, 23 were 
              found to be positive for CPV-2 by developed PCR. The disease was 
              found to be more common in Labrador male pups of 3-6 months of 
              age. The percentage of positive cases in vaccinated dogs was found 
              to be around 17.4%. 
              Conclusion: Almost half (52.3%) of total collected samples 
              were found to be positive by PCR. However, number of field samples 
              are needed to further validate this test and additionally sequence 
              analysis needs to be done to ensure the prevalent field strain of 
              CPV-2. 
              Keywords: Canine parvovirus type 2, fecal sample, polymerase 
              chain reaction.
