Abstract:
In the present study, serum samples from 402 sheep and 216 goats were collected
from 5 counties in Jinzhou from August to October 2012 and antibodies to Toxoplasma gondii
were detected by modified agglutination test (MAT). Overall, 104 (16.8%) had antibodies to T.
gondii with antibody titres of 1:25 to 1:800. Seropositive samples were distributed in all the
5 counties and seroprevalences of T. gondii varied significantly with flock size, age and
rearing system, but not with breed, gender and farm location. The seroprevalences in small
farms (18.3%, 95/518, 95% confidence interval [CI], 15.0-21.7%) were statistically higher than
that in large farms (9%, 9/100, 95% CI, 3.4-14.6%) (P < 0.05), older animals were statistically
higher than that in younger animals (P < 0.01). The prevalence in extensively and semiintensively
raised samples was statistically higher than that in intensively raised animals (P
< 0.01). Small flock size and extensive rearing system are the potential risk factors for the
prevalence of Toxoplasma infection in sheep and goats in Jinzhou. This is the first report of
T. gondii infection in sheep and goats in Jinzhou, northeastern China, and of an association of
seropositivity to T. gondii and the risk factors.
