Abstract

A serological survey was conducted in the Patagonia region of Argentina to estimate the prevalence of nine disease agents within the populations of free-ranging culpeo (Dusicyon culpaeus) and grey (Dusicyon griseus) foxes. The disease agents were Aujeszky's disease virus (ADV), Brucella, canine adenovirus (CAV), canine distemper virus (CDV), canine parvovirus (CPV), Encephalitozoon cuniculi, Leptospira, Neospora caninum, and Toxoplasma gondii. A total of 84 foxes were sampled (28 culpeo and 56 grey), and 73% of the sera had antibodies against one or more pathogens. Among these seropositive sera, 47% of them reacted to only one antigen, while the other 53% reacted to multiple antigens. The presence of antibodies to Toxoplasma (20%), Neospora (44%), Leptospira (30%) and Brucella (18%) suggests that these organisms actively circulate in the area. Antibodies against CDV, CAV and CPV were detected in 2%, 5% and 5% of foxes, respectively. Regarding Encephalitozoon cuniculi and ADV, no evidence of either was found.

摘要

在阿根廷巴塔哥尼亚地区进行了一项血清学调查，以估计自由放养的 Culpeo 狐（Dusicyon culpaeus）和灰狐（Dusicyon griseus）种群中九种病原体的流行情况。这些病原体包括奥耶斯基氏病病毒（ADV）、布鲁氏菌、犬腺病毒（CAV）、犬瘟热病毒（CDV）、犬细小病毒（CPV）、兔脑炎微孢子虫、钩端螺旋体、犬新孢子虫和刚地弓形虫。总共采集了 84 只狐狸的样本（28 只 Culpeo 狐和 56 只灰狐），73%的血清含有针对一种或多种病原体的抗体。在这些血清阳性样本中，47%仅对一种抗原产生反应，而另外 53%对多种抗原产生反应。针对弓形虫（20%）、新孢子虫（44%）、钩端螺旋体（30%）和布鲁氏菌（18%）的抗体存在表明这些病原体在该地区活跃传播。分别在 2%、5%和 5%的狐狸中检测到针对 CDV、CAV 和 CPV 的抗体。关于兔脑炎微孢子虫和 ADV，未发现相关证据。
