A serosurvey was performed to assess exposure to Toxoplasma gondii in zoo animals in Spain and to determine the dynamics of seropositivity in some zoo species over time. Sera from 393 zoo animals belonging to 91 species were collected in eight zoos in Spain between 2007 and 2019. Additionally, 39 of the 393 animals from five of the analyzed zoos were longitudinally sampled during the same study period. Antibodies to T. gondii were detected in 165 (42.0 %; CI95 %: 37.1-46.9) of 393 animals by the modified agglutination test (MAT, cut-off = 25). Antibody titers of 25, 50, 100 and ≥500 were found in 25 (15.2 %), 65 (39.4 %), 26 (15.8 %), and 49 (29.7 %) of the seropositive animals, respectively. Feeding habits (carnivorous species) was a risk factor (OR = 5.6; P < 0.001; CI95 %: 3.8-9.0) potentially associated with T. gondii exposure. Eighteen (46.2 %) of the 39 animals longitudinally sampled were always seropositive and five animals (12.8 %) (two spotted hyaena [Crocuta crocuta], one blesbok [Damaliscus pygargus], one white rhinoceros [Ceratotherium simum] and one mouflon [Ovis aries musimon]) seroconverted during the study period. Our results evince a wide circulation of T. gondii in zoos in Spain, including wild felids. Zoo animals can be useful sentinel species to monitor T. gondii circulation in epidemiological scenarios with a close human-wildlife interface. Control measures should be implemented in zoo parks to minimize the risk of exposure of zoo species to T. gondii.

在西班牙动物园动物中暴露于弓形虫。

进行了一次血清调查,以评估西班牙动物园动物中弓形虫的暴露情况,并确定某些动物园物种随时间推移的血清阳性反应的动态。在2007年至2019年之间,从西班牙的8个动物园中收集了来自91个物种的393种动物园动物的血清。此外,在同一研究期间,对来自五个分析动物园的393种动物中的39种进行了纵向采样。通过改良的凝集试验(MAT,截止值= 25),在393只动物的165只(42.0%; CI95%:37.1-46.9)中检测到弓形虫的抗体。在血清反应阳性动物中分别有25、50、100和≥500的抗体效价分别为25(15.2%),65(39.4%),26(15.8%)和49(29.7%)。喂养习惯(食肉动物)是可能与刚地弓形虫接触有关的危险因素(OR = 5.6; P <0.001; CI95%:3.8-9.0)。十八(46。纵向取样的39只动物中,有2%总是血清阳性的,有5只动物(12.8%)(有斑点的鬣狗[Crocuta crocuta],斑s [Damaliscus pygargus],白犀牛[Ceratotherium simum]和Mouflon [Ovis aries musimon] )在研究期间进行了血清转化。我们的结果表明,西班牙野生动物园中的弓形虫广泛传播,其中包括野生猫科动物。动物园动物可能是有用的前哨物种,可在流行病学场景中以紧密的人与野生动物界面来监视弓形虫的循环。应在动物园公园内实施控制措施,以最大程度地减少动物园物种接触弓形虫的风险。在研究期间血清转化了一只白犀牛(白犀草)和一只and头[Ovis aries musimon]。我们的结果表明,西班牙野生动物园中的弓形虫广泛传播,其中包括野生猫科动物。动物园动物可能是有用的前哨物种,可在流行病学场景中以紧密的人与野生动物界面来监视弓形虫的循环。应在动物园公园内实施控制措施,以最大程度地减少动物园物种接触弓形虫的风险。在研究期间血清转化了一只白犀牛(白犀草)和一只and头[Ovis aries musimon]。我们的研究结果表明,弓形虫在西班牙的动物园中广泛传播,包括野生猫科动物。动物园动物可能是有用的前哨物种,可在流行病学场景中以紧密的人与野生动物界面来监视弓形虫的循环。应在动物园公园内实施控制措施,以最大程度地减少动物园物种接触弓形虫的风险。
