摘要： Neospora caninum is an intracellular protozoan parasite which can cause abortion and stillbirth in ruminants. However, there is no information on Tibetan sheep N. caninum infection in China. A total of 2187 serum samples were collected from Tibetan sheep in the major production areas of Luqu, Maqu, and Tianzhu in Gansu province, and Nyingchi in southeast Tibet, China. All samples were analyzed for the presence of antibodies to N. caninum using a competitive-inhibition enzyme-linked immunoassay. Of the 2187 serum samples, 184 (8.4%, 95% CI 7.3-9.6) were tested N. caninum seropositive. The N. caninum seroprevalence ranged from 4.4% (95% CI 1.4-7.4) to 11.3% (95% CI 8.2-14.4) among different regions, seasons, ages, and pregnancies, and there was no statistical significance among those groups (P > 0.05). Seroprevalence in male (10.8% 69/638) (95% CI 8.4-13.2) was significantly higher than in female (7.4% 115/1549) (OR = 1.51, 95% CI 6.1-8.7) (P < 0.01). To our knowledge, this is the first report of N. caninum seroprevalence in Tibetan sheep in China, which provides baseline data for the prevention and control of N. caninum infection in Tibetan sheep.
