Three fishers (), 2 gray foxes (), 1 mink (), 1 skunk (), and 1 raccoon (), from Vermont and New Hampshire, had lesions on autopsy consistent with canine distemper virus (CDV) infections diagnosed in a 12-mo period in 2016-2017. Lesions of CDV infection were most commonly noted in the lungs (8 of 8 animals), urothelium (5 of 8), biliary tract (5 of 8), gastrointestinal tract (4 of 7), and brain (4 of 6). Splenic lesions were seen in 3 animals. The diagnosis was confirmed via immunohistochemistry and virus isolation. Viral genotyping indicated that all 8 animals were infected with a distinct clade of CDV that has only been reported in wildlife in New England, and this clade of viruses is distinct from vaccine strains. During the 12 mo when these cases occurred, no other CDV clade was identified in any other wildlife or domesticated animal submitted from the 2 states.
来自佛蒙特州和新罕布什尔州的3只渔貂、2只灰狐、1只水貂、1只臭鼬和1只浣熊在尸检时发现有病变，与2016 - 2017年12个月期间诊断出的犬瘟热病毒（CDV）感染相符。CDV感染的病变最常见于肺部（8只动物中的8只）、尿路上皮（8只中的5只）、胆道（8只中的5只）、胃肠道（7只中的4只）和脑部（6只中的4只）。3只动物出现脾脏病变。通过免疫组织化学和病毒分离确诊。病毒基因分型表明，所有8只动物都感染了一种独特的CDV分支，该分支仅在新英格兰的野生动物中被报道过，并且这种病毒分支与疫苗株不同。在这些病例发生的12个月期间，在这两个州提交的任何其他野生动物或家养动物中均未发现其他CDV分支。
