Abstract

We tested 30 serum samples collected during 2004-09 from 22 free-ranging Marsican brown bears (Ursus arctos marsicanus) in the National Park of Abruzzo, Lazio, and Molise, Italy, for antibodies against canine distemper virus (CDV), canine adenovirus type 2 (CAV-2), canine parvovirus type 2 (CPV-2), Brucella spp., and eight Leptospira interrogans sensu lato serovars. Antibody to CDV was detected in 11 samples (37%); only two bears (10%) had detectable CAV-2 and Brucella spp. antibodies; three bears were positive for L. interrogans serovar Bratislava; and one sample had antibody against L. interrogans serovar Copenhageni. All samples were positive for CPV-2 antibody. The CPV-2 antibody titers varied from 1∶640 to 1∶10,240, suggesting that transmission was still active. Fifty percent of bears were positive for antibody to two or more pathogens. Our results highlight the need to consider infectious diseases as a potential risk for Marsican brown bear conservation.

摘要

我们检测了2004年至2009年期间从意大利阿布鲁佐、拉齐奥和莫利塞国家公园的22只自由放养的马尔西坎棕熊（Ursus arctos marsicanus）采集的30份血清样本，以检测其针对犬瘟热病毒（CDV）、犬腺病毒2型（CAV - 2）、犬细小病毒2型（CPV - 2）、布鲁氏菌属以及8种问号钩端螺旋体血清型的抗体。在11份样本（37%）中检测到了针对CDV的抗体；只有两只熊（10%）检测到了CAV - 2和布鲁氏菌属的抗体；3只熊对问号钩端螺旋体布拉迪斯拉发血清型呈阳性；1份样本有针对问号钩端螺旋体哥本哈根血清型的抗体。所有样本对CPV - 2抗体均呈阳性。CPV - 2抗体滴度从1∶640到1∶10,240不等，表明传播仍在活跃进行。50%的熊对两种或更多病原体的抗体呈阳性。我们的结果凸显了将传染病视为马尔西坎棕熊保护的潜在风险的必要性。
