Abstract

In this study, serum samples of 203 animals from different locations, from zoos and breeding facilities from the north and northeast regions of Brazil, were analyzed for the presence of anti-Toxoplasma gondii antibodies by the modified agglutination test (MAT) with a cutoff of 1:25. Of the sampled animals, 184 were adult mammals of both sexes and 19 were birds. Antibodies were found in 61 of 184 mammals, and no association between sex and age of the animals and the presence of T. gondii antibodies was observed (P < 0.05). Anti-T gondii antibodies were not found in birds. Toxoplasma gondii was detected in Brazilian tapir (Tapirus terrestris) for the first time.

摘要

在本研究中，对来自巴西北部和东北部地区动物园及繁殖设施等不同地点的203只动物的血清样本进行分析，采用改良凝集试验（MAT）检测抗刚地弓形虫抗体，截断值为1:25。在采样的动物中，184只为成年雌雄哺乳动物，19只为鸟类。在184只哺乳动物中有61只检测到抗体，未观察到动物的性别和年龄与刚地弓形虫抗体存在之间的关联（P<0.05）。鸟类中未检测到抗刚地弓形虫抗体。首次在巴西貘（Tapirus terrestris）中检测到刚地弓形虫。
