Seroprevalence of Neospora caninum infection in dogs from rural and urban environments in Tehran, Iran.
103 serum samples were taken from owned dogs in Tehran (53 urban dogs and 50 farm dogs) from February to May 2005 and tested for IgG antibody against Neospora caninum using the immunofluorescence antibody test. Urban dogs were selected from apparent healthy dogs referred to the Small Animal Hospital of Faculty of Veterinary Medicine, University of Tehran, for routine operation, and the farm dogs were selected from the sheepdogs in sheep flocks around Tehran randomly. The titer of 1:50 was selected as cutoff. In total, 20 of 103 cases (19.4%) were identified as positive. The infection rate in farm dogs (28%) was higher than in urban dogs (11.3%), and the difference was statistically significant (p < 0.05). The infection rates in different genders and age groups were determined. The differences between seroprevalence of N. caninum infection in different sexes were not significant. A high correlation was observed between the infection rate and age (r (2) = 0.97, p < 0.01).
