Brazil has a large variety of wild animal species, but limited data are available on the occurrence of Brucella abortus and Leptospira spp. antibodies in these animals. Sera from 141 captive mammals belonging to 11 different species from the Northern and Northeastern regions of Brazil were screened. Antibodies against B. abortus and Leptospira spp. (24 live serovars) were investigated using the Rose Bengal plate and microscopic agglutination tests, respectively. Associations between the age, gender, and place of captivity were analyzed using the Pearson chi-square or the Fisher exact test. None of the animals were antibody positive for B. abortus. Among the animals tested, 11 (7.8%) were seropositive for Leptospira spp. These included one red brocket deer ( Mazama americana), two tufted capuchin ( Sapajus apella), seven agoutis ( Dasyprocta aguti), and one lowland paca ( Cuniculus paca). No association was observed between sex, age, and the occurrence of Leptospira spp. antibodies ( P > 0.05). However, an association was observed according to the place of captivity ( P = 0.046). From these 11 positive animals, six (54.5%) reacted to the serovars from the Icterohaemorraghiae serogroup, which is mainly responsible for the clinical cases of human leptospirosis in Brazil. To our knowledge, this is the first report of Leptospira spp. antibodies in M. americana and C. paca.
巴西有各种各样的野生动物物种，但关于这些动物中流产布鲁氏菌和钩端螺旋体属抗体的发生情况，可用数据有限。对来自巴西北部和东北部地区的11个不同物种的141只圈养哺乳动物的血清进行了筛查。分别使用玫瑰红平板试验和显微镜凝集试验检测针对流产布鲁氏菌和钩端螺旋体属（24种活血清型）的抗体。使用Pearson卡方检验或Fisher精确检验分析年龄、性别和圈养地点之间存在的关联。没有动物的流产布鲁氏菌抗体呈阳性。在接受检测的动物中，11只（7.8%）钩端螺旋体属血清学呈阳性。其中包括1只红短角鹿（美洲鹿）、2只簇绒卷尾猴（黑帽卷尾猴）、7只刺豚鼠（巴西刺豚鼠）和1只低地水豚（南美水豚）。未观察到性别、年龄与钩端螺旋体属抗体的出现之间存在关联（P>0.05）。然而，根据圈养地点观察到存在关联（P=0.046）。在这11只阳性动物中，6只（54.5%）对出血性黄疸型血清群的血清型有反应，该血清群是巴西人类钩端螺旋体病临床病例的主要病因。据我们所知，这是美洲鹿和南美水豚中钩端螺旋体属抗体的首次报告。
