This study aimed to verify the occurrence of antibodies against Toxoplasma gondii in rheas (Rhea americana) and ostriches (Struthio camelus) commercially breeding in Brazil. Blood samples from 20 rheas and 46 ostriches (young and adults) were serologically tested using a technique known as modified agglutination test (MAT) at an initial titration of 1:16 for ostriches and 1:25 for rheas. Antibodies against T. gondii were found in 50% (10/20) of the rheas, with titers ranging from 1:25 to 1:6,400. The incidence of antibodies against T. gondii in ostriches was 17.4% (8/46) with titers ranging from 1:16 to 1:256. Birds showing titers higher than 1:200 for T. gondii were mainly the young ones. Therefore, rheas and ostriches may be parasitized by T. gondii, showing high levels of antibodies against this parasite.
本研究旨在验证在巴西商业化养殖的美洲鸵鸟（Rhea americana）和鸵鸟（Struthio camelus）中抗刚地弓形虫抗体的出现情况。对20只美洲鸵鸟和46只鸵鸟（幼鸟和成年鸟）的血样进行了血清学检测，采用一种称为改良凝集试验（MAT）的技术，鸵鸟的初始滴度为1:16，美洲鸵鸟为1:25。在50%（10/20）的美洲鸵鸟中发现了抗刚地弓形虫抗体，滴度范围为1:25至1:6400。鸵鸟中抗刚地弓形虫抗体的发生率为17.4%（8/46），滴度范围为1:16至1:256。刚地弓形虫滴度高于1:200的鸟类主要是幼鸟。因此，美洲鸵鸟和鸵鸟可能被刚地弓形虫寄生，显示出针对这种寄生虫的高水平抗体。
