The frequency of Toxoplasma gondii antibodies in stray and household dogs in Guangzhou, China was examined by ELISA on serum samples from 150 animals (36 strays and 114 from households) and the overall prevalence was 21.3%. The extent of infection in stray dogs (33.3%) was significantly higher (P < 0.05) than in household dogs (17.5%). Infection in male and female dogs of both groups was not significantly different (P >or= 0.05), i.e., 31.8% versus 35.7% for male and female in stray dogs, and 14.5% versus 22.2% in household dogs. The results of the present investigation indicate that the seroprevalence of T. gondii infection in dogs was high in Guangzhou, especially in strays. Therefore, it is essential to implement integrated strategies to prevent and control T. gondii infection in both stray and household dogs.
通过酶联免疫吸附测定法（ELISA）检测了中国广州150只动物（36只流浪狗和114只家养宠物狗）血清样本中弓形虫抗体的频率，总体患病率为21.3%。流浪狗的感染率（33.3%）显著高于家养宠物狗（17.5%）（P < 0.05）。两组中雄性和雌性狗的感染情况无显著差异（P≥0.05），即流浪狗中雄性和雌性的感染率分别为31.8%和35.7%，家养宠物狗中分别为14.5%和22.2%。本次调查结果表明，广州狗的弓形虫感染血清阳性率很高，尤其是流浪狗。因此，实施综合策略预防和控制流浪狗和家养宠物狗的弓形虫感染至关重要。
