The prevalence of seropositive reactions to Toxoplasma gondii was studied in farm animals, companion animals, wild rodents and birds. Of the animals tested, 17% of cattle, 65% of sheep, 45% of pigs, 9% of horses, 33% of dogs and 20% of cats were seropositive by the Sabin-Feldman dye test. In addition 11% of mice (Mus musculus), 5% of deer mice (Peromyscus), 3% of rats (Rattus norvegicus) and less than 2% of sparrows (Passer domestcus) were seropositive. All samples from short-tailed field mice (Microtus pennsylvanicus), squirrels (Sciurus carolinensis), chipmunks (Tamias striatus), meadow jumping mice (Zapus hudsonius) and starlings (Sturnus vulgaris) were seronegative. The significance of these findings in relation to the epizootiology of toxoplasmosis in Ontario is discussed.
对农场动物、伴侣动物、野生啮齿动物和鸟类进行了弓形虫血清阳性反应患病率的研究。在接受检测的动物中,通过Sabin - Feldman染色试验,17%的牛、65%的绵羊、45%的猪、9%的马、33%的狗和20%的猫血清呈阳性。此外,11%的小鼠(小家鼠)、5%的鹿鼠(白足鼠属)、3%的大鼠(褐家鼠)和不到2%的麻雀(家麻雀)血清呈阳性。来自短尾田鼠(宾夕法尼亚田鼠)、松鼠(卡罗来纳松鼠)、花栗鼠(条纹金花鼠)、草原林跳鼠(哈德逊林跳鼠)和椋鸟(紫翅椋鸟)的所有样本血清均为阴性。讨论了这些发现与安大略省弓形虫病动物流行病学的关系。
