温州市犬弓形虫病流行病学调查

Epidemiological survey of Toxoplasmosis in dogs in Wenzhou

为研究温州市犬弓形虫病感染情况,应用酶联免疫吸附试验,检测351份血液样本。结果显示,本地区犬的弓形虫Ig G抗体阳性率为13.39%（47/351）;公犬与雌犬阳性率差异不显著（P〉0.05）,绝育/去势犬的阳性率显著低于未进行绝育/去势的犬（P〈0.05）;成年犬Ig G抗体阳性率大大高于幼年犬和老年犬;流浪犬抗体阳性率最高,训导场内的犬最低,家养犬居中;不同饲喂食物下的犬,其Ig G抗体阳性率差异较大。

To determine the seroprevalence of Toxoplsama gondii among dogs in the Wenzhou region,plasma samples of 351 dogs were collected and tested for Toxoplasma gondii antibodies by ELISA. Toxoplasma gondii Ig G antibodies were detected in 47（ 13. 39%） of the sampled dogs. The positive rates showed no significant difference between male and female dogs（ 0. 05）,and the seroprevalence was significantly lower in neutered dogs than in intact dogs（ P〈0. 05）. The infection prevalence was higher in adult dogs than in young and geriatric dogs,and it was significantly higher in stray dogs than in household dogs and in those in the training field. Significant variation in seropositivity was found between different diets.
