Raccoon (Procyon lotor) carcasses (n=118) were collected from July through December 2007 throughout eastern Tennessee. Necropsies were performed, and Baylisascaris procyonis was collected from the gastrointestinal tract of infected carcasses. Prevalence rates were determined for the overall sample population, males and females, and adults and juveniles. The sample population had a B. procyonis prevalence of 12.7%. Males and females had a prevalence of 15% and 11%, respectively; prevalence in adults and juvenile was 13% and 12.6%, respectively. There were no significant differences in prevalence rates between the different groups. Baylisascaris procyonis is an ascarid infection of raccoons that can infect humans and over 100 species of other animals. The presence of infection in raccoons, paired with the expansion of human populations in eastern Tennessee, is likely to lead to increased interactions between humans and raccoons and therefore an increased risk of human and domestic animal exposure to B. procyonis.
2007年7月至12月期间，在田纳西州东部各地收集了118只浣熊尸体。进行了尸检，并从受感染尸体的胃肠道中采集到了浣熊贝蛔虫。确定了整个样本群体、雄性和雌性以及成年和幼年浣熊的感染率。样本群体中浣熊贝蛔虫的感染率为12.7%。雄性和雌性的感染率分别为15%和11%；成年和幼年的感染率分别为13%和12.6%。不同组之间的感染率没有显著差异。浣熊贝蛔虫是浣熊的一种蛔虫感染，可感染人类和100多种其他动物。浣熊体内存在这种感染，再加上田纳西州东部人口的增长，可能会导致人类与浣熊之间的接触增加，从而增加人类和家畜接触浣熊贝蛔虫的风险。
