Abstract：
This study documents the presence of anti-Neospora caninum antibodies and their association with certain risk factors in 2 deer species from the central region of Veracruz State, Mexico. A total of 90 blood samples, 20 from temazate deer (Mazama temama) and 70 from white-tailed deer (Odocoileus virginianus), were taken from 3 farms, and serum samples were subjected to ELISA indirect test to detect N. caninum antibodies; the association between the serological status and the possible risk factors was then estimated. The overall presence of anti-N. caninum antibodies was 57.7% (52/90; 95% CI 46.9-67.9), with positive animals identified on all farms; in white-tailed deer it was 57% and in temazate deer 60%. Prevalence was higher in females than males. Adult animals had a higher prevalence than young ones. The risk analysis identified the age in the adult animal category (odds ratio 5.8) as being associated with the presence of anti-N. caninum antibodies. These results provide evidence of the significant contamination of oocysts in the environment and allow us to estimate the contribution of deer to the sylvatic cycle.
摘要：
这项研究记录了韦拉克鲁斯州中部地区2种鹿中抗犬新孢子抗体的存在及其与某些危险因素的关联，墨西哥。总共有90份血样,20来自temazate鹿（Mazamatemama），70来自白尾鹿（Odocoileusvirginianus），取自三个农场，和血清样本进行ELISA间接试验以检测犬奈米杆菌抗体;然后估计血清学状态与可能的危险因素之间的关联。反N的整体存在犬抗体为57.7%（52/90；95%CI46.9-67.9），在所有农场中都发现了阳性动物；在白尾鹿中，它是57％，在temazate鹿中，它是60％。女性患病率高于男性。成年动物的患病率高于幼年动物。风险分析确定成年动物类别中的年龄(比值比5.8)与抗N的存在相关。caninum抗体.这些结果提供了环境中卵囊严重污染的证据，并使我们能够估计鹿对sylvatic循环的贡献。
