Antigenic detection of Canine Distemper virus infection in the affected dogs to respiratory diseases, referred to Veterinary Hospital of Ahvaz

Canine distemper virus (CDV) is one of the most common diseases in young dogs. Agent of disease is a Morbillivirus of Paramyxoviridae family. Distemper is seen to different forms digestive, respiratory, neurologic, cutaneous and optical. In the onset of diseases, virus is high in secretions of eye and nose. The present study was conducted to determine the prevalence of Canine distemper virus infection in referred dogs to Veterinary Hospital of Ahvaz. A total of 96 samples of secretions of the affected dogs with respiratory diseases were obtained randomly between June 2008 and December 2009. The studied dogs were divided into two age groups (<6 months and > 6 months) and based on environment into two groups (open and close) also. The results were analyzed by using Chi-square analysis and Fischerʹs exact test. Prevalence to Canine distemper virus antigens was 7.29% (7 of 96) by means of immunochromatography (sensitivity and specificity above 95%). The infection had more prevalence in those dogs that were in open environment (17.09%) in compared with close environment (1.75%) and the difference was significant between different groups (P=0.008). Prevalence was more in dogs less than 6 months (8.2%) in compared with dogs above 6 months (5.71%), but the difference was not statistically significant between two groups (P>0.05). Prevalence of infection was 8.11% in male dogs and 6.78% in female dogs. There was no significant difference between two sexes and different breeds also (P>0.05). All of the affected dogs were not vaccinated. This study showed that Canine distemper virus can be as a risk factor especially for none-vaccinated dogs that are in contact together, in open environment and kennel.
