ABSTRACT
Haemorrhagic gastroenteritis in canine is caused by different etiological agents like canine parvovirus, E.coli, Salmonella, Campylobacter, Coccidia and Giardia, among these agents canine parvovirus is the most important. Canine parvovirus binds to the sialic acid receptors which are present on the RBC’s, so haemagglutination test is used to detect canine parvovirus. In this study a total (n=102) of faecal samples from canines having haemorrhagic gastroenteritis were taken. All the 102 samples were subjected to haemagglutination assay and the prevalence of CPV was studied. Host associated risk factors like age, sex, breed, vaccination and seasons responsible for occurrence of canine parvovirus infection are recorded. Out of the 102 samples haemagglutination assay detected 41 samples as positive and a percent positivity of (40.19%) was recorded by this diagnostic test. Age wise prevalence was (69.23%) in (0-6 month) age group which is more than (7-12 month) (13.33%) and more than a year group (5%). Sex wise prevalence was more in males (47.94%) than in females (20.78%). Breed wise prevalence was more in Labrador (78.57%) followed by Doberman Pinscher (62.50%) lower prevalence was reported in Pomerarian and German shephered breeds. Non vaccinated canines showed a high prevalence of (42.70%) and in vaccinated canines no disease prevalence was detected. In the season wise prevalence, spring season showed more prevalence (54.76%) followed by summer season which showed (37.5%) prevalence and the least prevalence of (11.11%) was recorded in the winter season. Study showed that Haemagglutination assay is a good diagnostic test for the study of canine parvovirus where modern facilities of molecular diagnosis and the costly faecal ELISA test kits are not available.
