The aim of the present study was to investigate antibodies to Toxoplasma gondii in the serum of mules and donkeys bred in the northeast of Brazil. In total, 483 samples were used (395 mules and 88 donkeys) from 4 states (Pernambuco, Rio Grande do Norte, Paraíba, and Sergipe). The indirect immunofluorescence reaction (IFI) technique was used to investigate antibodies to T. gondii with a cut-off point of 64. Positive frequencies of 23.8% and 43.2% were recorded for mules and donkeys, respectively. The state of Pernambuco had the highest prevalence of positive samples (29%) with statistically significant differences for species (P < 0.001) and state (P = 0.048). This is the first study of antibodies to T. gondii in mules and donkeys in these 4 states of the northeastern region of Brazil and serves as a warning to health authorities regarding the risks of ingesting equine meat.
本研究的目的是调查巴西东北部饲养的骡子和驴血清中的弓形虫抗体。总共使用了来自4个州（伯南布哥州、北大河州、帕拉伊巴州和塞尔希培州）的483份样本（395头骡子和88头驴）。采用间接免疫荧光反应（IFI）技术检测弓形虫抗体，临界值为64。骡子和驴的阳性频率分别为23.8%和43.2%。伯南布哥州阳性样本的患病率最高（29%），物种（P < 0.001）和州（P = 0.048）之间存在统计学显著差异。这是巴西东北地区这4个州首次对骡子和驴的弓形虫抗体进行研究，为卫生当局敲响了食用马肉风险的警钟。
