Objective: Canine parvovirus infection (CPV) occurs worldwide in domestic dogs and wild canids and occur in dogs of any age. Our study designated to investigate the incidence, clinical signs and hematological changes occurred during parvovirus enteritis in dogs
Design and procedure: Eighty fecal samples collected from rectum of clinically healthy and CPV infected dogs and examined by SNAP* Parvo test, 20 cases were negative with SNAP* Parvo adopted as control and 60 cases were positive with SNAP* Parvo categorized as CPV group. Blood samples obtained from cephalic vein and lateral saphenous vein and mixed with EDTA as anticoagulant for hematological studies.
Results: CPV show a higher incidence in German shepherd (30%), Rottweiler (20%), Doberman (16.7%), Golden retriever (13.3%), Pitbull (10%), Husky (5%), Tibetan mastiff (5%). CPV mostly affect the age group from 6 weeks to 3-month-old puppies (86.67%) and affect age group from 3-6 month of age (13.33%) and more frequent in males (68.33%) than females (31.67%). About 27% of CPV enteritis cases suffer from macrocytic hypochromic anemia and 73.33% of cases suffer from normocytic normochromic anemia. Leukopenia, lymphopenia and neutropenia were the pronounced feature of CPV in 78.33%, however, leukocytosis, lymphocytosis and neutropenia also recorded in our study by 21.67% of CPV enteritis cases. Platelets count reveal a significant decrease in all CPV enteritis cases.
Conclusion and clinical relevance: Descriptive incidence, clinical signs of CPV are very helpful for tentative diagnosis of CPV as well as hematological changes occurred during CPV infection in dogs.
