This is a cross-sectional study to assess the presence of antibodies in ruminants against selected pathogens associated with reproductive disorders in cattle in four Brazilian states, including the zoonotic agent Coxiella burnetii. The used tests were Virus Neutralization Assay for IBR and BVD, Microscopic Agglutination Test for Leptospira spp., Indirect Fluorescent Antibody Test (IFAT) for C. burnetii and Toxoplasma gondii, and Enzyme-Linked Immunosorbent Assay for Neospora caninum and Trypanosoma vivax. Seropositivity for C. burnetii was 13.7% with titers from 128 to 131,072; 57.8% for BoHV-1, with titers between 2 and 1,024; 47.1% for BVDV-1a, with titers from 10 to 5,120; 89.2% for N. caninum; 50% for T. vivax; and 52.0% for Leptospira spp., with titers between 100 to 800 (the following serovars were found: Tarassovi, Grippotyphosa, Canicola, Copenhageni, Wolffi, Hardjo, Pomona and Icterohaemorrhagiae); 19.6% for T. gondii with titer of 40. This is the first study that has identified C. burnetii in cattle associated with BoHV and BVDV, N. caninum, Leptospira spp., T. gondii and T. vivax. Thus, future studies should be conducted to investigate how widespread this pathogen is in Brazilian cattle herds.
这是一项横断面研究，旨在评估巴西四个州的反刍动物体内针对与牛繁殖障碍相关的特定病原体的抗体存在情况，其中包括人畜共患病原体伯氏考克斯体。所采用的检测方法包括用于传染性牛鼻气管炎（IBR）和牛病毒性腹泻（BVD）的病毒中和试验、用于钩端螺旋体属的显微镜凝集试验、用于伯氏考克斯体和刚地弓形虫的间接荧光抗体试验（IFAT），以及用于犬新孢子虫和活泼锥虫的酶联免疫吸附测定。伯氏考克斯体的血清阳性率为13.7%，滴度为128至131,072；牛疱疹病毒1型（BoHV-1）为57.8%，滴度在2至1,024之间；牛病毒性腹泻病毒1a型（BVDV-1a）为47.1%，滴度为10至5,120；犬新孢子虫为89.2%；活泼锥虫为50%；钩端螺旋体属为52.0%，滴度在100至800之间（发现了以下血清型：塔拉索维、致热钩端螺旋体、犬型钩端螺旋体、哥本哈根型钩端螺旋体、沃尔夫型钩端螺旋体、哈焦型钩端螺旋体、波摩那型钩端螺旋体和出血黄疸型钩端螺旋体）；刚地弓形虫为19.6%，滴度为40。这是首次在与BoHV、BVDV、犬新孢子虫、钩端螺旋体属、刚地弓形虫和活泼锥虫相关的牛中鉴定出伯氏考克斯体。因此，未来应开展研究以调查该病原体在巴西牛群中的传播程度。
