We tested serum samples from 387 free-ranging wolves ( Canis lupus ) from 2007 to 2013 for exposure to eight canid pathogens to establish baseline data on disease prevalence and spatial distribution in Minnesota's wolf population. We found high exposure to canine adenoviruses 1 and 2 (88% adults, 45% pups), canine parvovirus (82% adults, 24% pups), and Lyme disease (76% adults, 39% pups). Sixty-six percent of adults and 36% of pups exhibited exposure to the protozoan parasite Neospora caninum . Exposure to arboviruses was confirmed, including West Nile virus (37% adults, 18% pups) and eastern equine encephalitis (3% adults). Exposure rates were lower for canine distemper (19% adults, 5% pups) and heartworm (7% adults, 3% pups). Significant spatial trends were observed in wolves exposed to canine parvovirus and Lyme disease. Serologic data do not confirm clinical disease, but better understanding of disease ecology of wolves can provide valuable insight into wildlife population dynamics and improve management of these species.
2007年至2013年，我们检测了387只明尼苏达州野生狼（Canis lupus）的血清样本，以确定其对八种犬科病原体的暴露情况，从而建立该州狼种群疾病流行率和空间分布的基线数据。我们发现狼对犬腺病毒1型和2型（成年狼88%，幼狼45%）、犬细小病毒（成年狼82%，幼狼24%）和莱姆病（成年狼76%，幼狼39%）的暴露率很高。66%的成年狼和36%的幼狼显示暴露于犬新孢子虫原虫寄生虫。确认狼暴露于虫媒病毒，包括西尼罗河病毒（成年狼37%，幼狼18%）和东部马脑炎病毒（成年狼3%）。犬瘟热（成年狼19%，幼狼5%）和心丝虫（成年狼7%，幼狼3%）的暴露率较低。在暴露于犬细小病毒和莱姆病的狼中观察到显著的空间趋势。血清学数据不能确诊临床疾病，但更好地了解狼的疾病生态学可以为野生动物种群动态提供有价值的见解，并改善对这些物种的管理。
