Tissue cysts of Besnoitia sp. were found in muscles and several organs from a naturally infected Akodon montensis captured in the rural area of the municipality of Timbó, Santa Catarina State, in southern Brazil. Indirect fluorescence and enzyme-linked immunosorbent assays carried out with sera from mice chronically infected with Toxoplasma gondii and Besnoitia sp. showed, as expected, a stronger reaction against homologous than heterologous antigens. No cross-protection was observed in mice immunized with T. gondii when challenged with Besnoitia sp. This is the first description of a natural infection of A. montensis by parasites of the genus Besnoitia sp. in Brazil.
在巴西南部圣卡塔琳娜州廷博市农村地区捕获的一只自然感染的蒙氏稻鼠的肌肉和多个器官中发现了贝斯诺伊属组织囊肿。用慢性感染刚地弓形虫和贝斯诺伊属的小鼠血清进行的间接荧光和酶联免疫吸附试验表明，正如预期的那样，同源抗原比异源抗原引发的反应更强。用刚地弓形虫免疫的小鼠在用贝斯诺伊属攻击时未观察到交叉保护作用。这是巴西首次描述蒙氏稻鼠被贝斯诺伊属寄生虫自然感染的情况。
