Serum samples from 697 Rocky Mountain bighorn sheep (Ovis canadensis) from North America were examined for antibodies to Toxoplasma gondii by the modified agglutination test incorporating mercaptoethanol and formalin-fixed tachyzoites. Antibodies to T. gondii were found in 25 of 697 (3.6%) sheep in titers of 1:25 (8 sheep), 1:50 (4 sheep), 1:100 (7 sheep), 1:200 (1 sheep), 1:400 (1 sheep), 1:800 (1 sheep), and 1:1,600 (3 sheep). This is the first record of T. gondii exposure in bighorn sheep.
采用含巯基乙醇和福尔马林固定速殖子的改良凝集试验,检测了来自北美697只落基山大角羊(加拿大盘羊)的血清样本中的抗刚地弓形虫抗体。在697只羊中的25只(3.6%)检测到抗刚地弓形虫抗体,滴度分别为1:25(8只羊)、1:50(4只羊)、1:100(7只羊)、1:200(1只羊)、1:400(1只羊)、1:800(1只羊)和1:1600(3只羊)。这是大角羊接触刚地弓形虫的首次记录。
