Abstract

Abstract:

In order to identify the infection of Toxoplasma gondii in dogs and cats in Beijing, according to the program of animal disease surveillance in Beijing in 2022, 920 dog serum samples and 816 cat serum samples were collected from scatters, animal hospitals and farms in the whole city. Indirect heamagglutination assay were uesd to detecte Toxoplasma gondii antibodies in dog and cat serum samples. The result shows that the T. gondii antibody positive rate was 5.2% (48/920) in dogs and 7.5% (61/816) in cats. The positive rate of T. gondii antibody in dogs in autumn was 6.8% (30/440), which was higher than that in spring at 3.8% (18/480) with moderate intensity correlation (χ² = 4.37，P < 0.05，0.4 < OR < 0.6). And the positive rate of T. gondii antibody in cats in autumn was 12.5% (50/401), which was higher than that in spring at 2.7% (11/415) with strongly correlated material (χ² = 28.42，P < 0.05，0.1 < OR < 0.3）. In diverse sources, the positive rates of T. gondii antibody in dogs and cats from veterinary clinics were the highest, which were 8.0% (47/590) and 8.5% (61/715) (χ² = 25.31, 9.31，all P < 0.05), respectively. The positive rate of T. gondii antibody in dogs from the six central districts was 11.4%（40/350）. The positive rate of T. gondii antibody in dogs from the outer suburban districts was 1.4% (8/570) with strongly correlated material (χ² = 44.07，P < 0.05，3.0 < OR < 9.9). And the positive rate of T. gondii antibody in cats from the six central districts was 10.3% (37/360). The positive rate of T. gondii antibody in cats from the outer suburban districts was 5.3% (24/456) with moderate intensity correlation (χ² = 7.31，P < 0.05，1.5 < OR < 2.9). This study provided a basis for the further prevention and control of toxoplasmosis in Beijing.
