This study was designed to detect antibodies to Toxoplasma gondii and Neospora caninum in wild captive carnivores maintained in Brazilian zoos. Blood samples were collected from 142 Brazilian wild felids and 19 exotic felids in zoos, and 3 European wolves (Canis lupus) and 94 Brazilian wild canids maintained in captivity in Brazilian zoos of São Paulo, Mato Grosso states and Federal District. One hundred and two (63.4%) and 70 (50.3%) of the 161 wild felids tested were seropositive for T. gondii and N. caninum by indirect immunofluorescent assay test (IFAT), respectively. Among sampled wild canids, 49 (50.5%) and 40 (41.2%) animals were seropositive for T. gondii and N. caninum antigens by IFAT, respectively. To our knowledge, this is the first serological detection of antibodies to N. caninum in Brazilian wild captive felids and bush dogs (Speothos venaticus (Lund)).
本研究旨在检测巴西动物园饲养的野生圈养食肉动物体内抗刚地弓形虫和犬新孢子虫的抗体。从142只巴西野生猫科动物、动物园里的19只外来猫科动物，以及圣保罗、马托格罗索州和联邦区巴西动物园圈养的3只欧洲狼（犬属灰狼）和94只巴西野生犬科动物采集血样。通过间接免疫荧光试验（IFAT）检测，161只野生猫科动物中分别有102只（63.4%）和70只（50.3%）对刚地弓形虫和犬新孢子虫血清学呈阳性。在采样的野生犬科动物中，分别有49只（50.5%）和40只（41.2%）动物对刚地弓形虫和犬新孢子虫抗原通过IFAT血清学呈阳性。据我们所知，这是巴西野生圈养猫科动物和丛林犬（Speothos venaticus (Lund)）中首次对犬新孢子虫抗体进行血清学检测。
