摘要：

为了解北京市犬、猫刚地弓形虫感染情况，根据“2022年北京市动物疫病监测实施方案”，从全市不同区域的散户、动物医院、养殖场采集并提取犬血清920份、猫血清816份，采用间接血凝试验进行弓形虫抗体检测。结果显示，犬和猫血清弓形虫抗体阳性率分别为5.2%（48/920）和7.5%（61/816）。秋季犬血清弓形虫抗体阳性率为6.8%（30/440），高于春季的3.8%（18/480），具有中等强度关联（χ² = 4.37，P < 0.05，0.4 < OR < 0.6）；秋季猫血清弓形虫抗体阳性率为12.5%（50/401），也高于春季的2.7%（11/415），具有强关联（χ² = 28.42，P < 0.05，0.1 < OR < 0.3）。不同来源中，动物医院的犬、猫血清弓形虫抗体阳性率均为最高，分别为8.0%（47/590）和8.5%（61/715）（χ² = 25.31、9.31，均P < 0.05）。城六区犬血清抗体阳性率为11.4%（40/350），远郊区的为1.4%（8/570），具有强关联（χ² = 44.07，P < 0.05，3.0 < OR < 9.9）；城六区猫血清抗体阳性率为10.3%（37/360），远郊区的为5.3%（24/456），具有中等强度关联（χ² = 7.31，P < 0.05，1.5 < OR < 2.9）。该调查结果为北京市弓形虫病的防治提供数据参考。

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.
