Abstract

Following a canine distemper virus (CDV) epizootic in 2011, serum samples of 45 live-trapped desert kit foxes (Vulpes macrotis arsipus) from the Upper Chuckwalla Valley, California, US, were tested for the presence of antibodies against CDV, canine parvovirus (CPV), canine herpes virus (CHV), canine adenovirus (CAV-2), and Toxoplasma gondii. Fecal swabs were tested by PCR for CPV genomic material, and ocular and nasal swabs were assessed for genomic material of CDV, CHV, CAV-2, influenza virus (H3N8), parainfluenza, canine respiratory coronavirus, Bordetella bronchiseptica, and Streptococcus equi subsp. zooepidemicus. Fourteen foxes (31.1%) were positive in at least one test, with exposure and/or infection confirmed for CDV (6/45, 13.3%), CPV (4/45, 8.9%), S. equi subsp. zooepidemicus (4/45, 8.9%), and T. gondii (2/45, 4.4%). Study results were similar to results reported for kit foxes in other portions of their distribution. Further research with long-term regular testing is needed to understand disease dynamics in kit fox populations better.

摘要

在 2011 年犬瘟热病毒（CDV）爆发后，美国加利福尼亚州上 Chuckwalla 谷的 45 只活捕沙漠狐（Vulpes macrotis arsipus）血清样本被检测是否存在针对 CDV、犬细小病毒（CPV）、犬疱疹病毒（CHV）、犬腺病毒（CAV-2）和刚地弓形虫的抗体。通过 PCR 检测粪便拭子中 CPV 的基因组物质，通过眼和鼻拭子评估 CDV、CHV、CAV-2、H3N8 流感病毒、副流感病毒、犬呼吸道冠状病毒、支气管败血波氏杆菌和马链球菌兽疫亚种的基因组物质。14 只狐狸（31.1%）至少在一项检测中呈阳性，证实 CDV（6/45，13.3%）、CPV（4/45，8.9%）、S. equi subsp. zooepidemicus（4/45，8.9%）和 T. gondii（2/45，4.4%）暴露和/或感染。研究结果与在其分布的其他地区报道的狐属动物的结果相似。需要进一步进行长期定期检测的研究，以更好地了解狐属动物种群的疾病动态。
