摘要

摘要原圆虫Baylisacaris procyonis是一种蛔虫，其主要宿主浣熊（Procyon lotor）对其具有耐受性。然而，这种蛔虫对中间哺乳动物宿主可能是致命的，并可能是濒危阿勒格尼伍德鼠（Neotoma magister）种群减少的一个因素。我们使用粪便漂浮法来确定在大西洋中部与木鼠栖息地重叠的地方发现的浣熊粪便中的B.procyonis卵的流行率。我们确定，在马里兰州和宾夕法尼亚州的两个现存的木鼠群落中都存在B.procyonis。如果蛔虫和其他因素（如森林破碎化）得不到缓解，我们预计这些地点的木鼠数量将下降。

The Prevalence of the Raccoon Roundworm, Baylisascaris procyonis, in Allegheny Woodrat Habitat in the Mid-Atlantic Region, U.S.A.

Abstract. Baylisacaris procyonis is a roundworm that is tolerated by its primary host, raccoons (Procyon lotor). However, this roundworm can be fatal to intermediate mammalian hosts and may be a contributing factor to population declines of the endangered, Allegheny woodrat (Neotoma magister). We used fecal flotation to determine the prevalence of B. procyonis eggs in raccoon scat found in locations that overlap with where woodrats persist in the mid-Atlantic. We determined that B. procyonis was present at two extant woodrat colonies in Maryland and Pennsylvania. We expect woodrat populations at these sites to decline, if the roundworm and other factors (e.g., forest fragmentation) are not alleviated.

期刊介绍： The American Midland Naturalist has been published for 90 years by the University of Notre Dame. The connotations of Midland and Naturalist have broadened and its geographic coverage now includes North America with occasional articles from other continents. The old image of naturalist has changed and the journal publishes what Charles Elton aptly termed "scientific natural history" including field and experimental biology. Its significance and breadth of coverage are evident in that the American Midland Naturalist is among the most frequently cited journals in publications on ecology, mammalogy, herpetology, ornithology, ichthyology, parasitology, aquatic and invertebrate biology and other biological disciplines.
