Coyotes (Canis latrans) have expanded recently into the eastern US and can serve as a source of pathogens to domestic dogs (Canis lupus familiaris), livestock, and humans. We examined free-ranging coyotes from central North Carolina, US, for selected parasites and prevalence of antibodies against viral and bacterial agents. We detected ticks on most (81%) coyotes, with Amblyomma americanum detected on 83% of those with ticks. Fifteen (47%) coyotes were positive for heartworms (Dirofilaria immitis), with a greater detection rate in adults (75%) than juveniles (22%). Serology revealed antibodies against canine adenovirus (71%), canine coronavirus (32%), canine distemper virus (17%), canine parvovirus (96%), and Leptospira spp. (7%). We did not detect antibodies against Brucella abortus/suis or Brucella canis. Our results showed that coyotes harbor many common pathogens that present health risks to humans and domestic animals and suggest that continued monitoring of the coyote's role in pathogen transmission is warranted.
郊狼（犬属）最近已扩展到美国东部，并且可作为病原体的来源，传播给家犬（家犬种）、家畜和人类。我们检查了来自美国北卡罗来纳州中部的野生郊狼，以检测特定寄生虫以及针对病毒和细菌病原体的抗体流行情况。我们在大多数（81%）郊狼身上检测到蜱虫，在有蜱虫的郊狼中，83%检测到美洲钝眼蜱。15只（47%）郊狼的心丝虫（犬恶丝虫）呈阳性，成年郊狼（75%）的检出率高于幼年郊狼（22%）。血清学检测显示存在针对犬腺病毒（71%）、犬冠状病毒（32%）、犬瘟热病毒（17%）、犬细小病毒（96%）和钩端螺旋体属（7%）的抗体。我们未检测到针对流产布鲁氏菌/猪布鲁氏菌或犬布鲁氏菌的抗体。我们的结果表明，郊狼携带许多对人类和家畜具有健康风险的常见病原体，并表明有必要持续监测郊狼在病原体传播中的作用。
