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.
本研究记录了墨西哥韦拉克鲁斯州中部的 2 种鹿种中抗新型隐球菌抗体的存在及其与某些危险因素的关联。从 3 个农场采集了 90 份血液样本，其中 20 份来自塔马泰鹿（Mazama temama），70 份来自白尾鹿（Odocoileus virginianus），并对血清样本进行了酶联免疫吸附试验（ELISA）间接检测，以检测抗新型隐球菌抗体；然后估计了血清学状态与可能的危险因素之间的关联。抗新型隐球菌抗体的总阳性率为 57.7%（52/90；95%CI 46.9-67.9），所有农场均有阳性动物；白尾鹿的阳性率为 57%，塔马泰鹿的阳性率为 60%。雌性动物的阳性率高于雄性动物。成年动物的阳性率高于幼龄动物。风险分析确定成年动物类别的年龄（优势比 5.8）与抗新型隐球菌抗体的存在相关。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森林循环的贡献。
