Toxoplasma gondii is an apicomplexan protozoan that is frequently found in both humans and animals worldwide. The aim of this review was to list important aspects of Toxoplasma gondii infection in cattle in Brazil. The frequency of occurrence of T. gondii antibodies in Brazilian cattle ranges from 1 to 89.1%, depending on the region evaluated, based on data from 1978 to 2018. However, some characteristics of T. gondii infection in cattle remain uncertain, such as the role of meat intake in transmitting the parasite to humans. Most information regarding T. gondii infection among Brazilian cattle is limited to evaluations of the frequency of occurrence of antibodies. About 70% of the diagnoses of infection in these ruminants in Brazil are made via the indirect fluorescence antibody test (IFAT). Nevertheless, little is known about the population structure of this protozoan in cattle. It is necessary to expand the studies on toxoplasmosis in cattle, in order to better understand T. gondii infection in these animals and its implications for Brazilian public health.
刚地弓形虫是一种顶复门原生动物，在全球范围内的人类和动物中都经常被发现。本综述的目的是列出巴西牛群中刚地弓形虫感染的重要方面。根据1978年至2018年的数据，巴西牛群中刚地弓形虫抗体的出现频率在1%至89.1%之间，这取决于所评估的地区。然而，牛群中刚地弓形虫感染的一些特征仍不明确，例如肉类摄入在将寄生虫传播给人类方面的作用。关于巴西牛群中刚地弓形虫感染的大多数信息仅限于抗体出现频率的评估。在巴西，这些反刍动物中约70%的感染诊断是通过间接荧光抗体试验（IFAT）进行的。然而，对于这种原生动物在牛群中的种群结构知之甚少。有必要扩大对牛弓形虫病的研究，以便更好地了解这些动物中的刚地弓形虫感染及其对巴西公共卫生的影响。
