摘要

摘要:在美国南部的阿巴拉契亚山脉，俄勒冈吸虫(Metagonimoides oregonensis)是一种浣熊寄生虫，也可能是水貂的寄生虫，它以无肺蝾螈的幼虫为第二中间宿主，其中最常见的寄主是quadramaculatus Desmognathus。我们在乔治亚州北部测试了这种蝾螈和它的同域、隐蔽的同族蝾螈在寄生虫感染方面是否存在差异。在18 ~ 1000余种烈度范围内，方头田鼠幼虫的流行率为100%，而民间田鼠未发现明显的囊蚴。这些结果表明，在南部阿巴拉契亚地区，oregonensis对蝾螈第二中间宿主的特异性比以往报道的要高。

Differential Infection of Two Sympatric, Cryptic Species of Appalachian Salamander (Genus Desmognathus) by the Trematode Metagonimoides oregonensis

ABSTRACT: In the southern Appalachian Mountains, U.S.A., the trematode Metagonimoides oregonensis, a parasite of raccoons and possibly mink, utilizes larvae of lungless salamanders as second intermediate hosts, most frequently using the salamander Desmognathus quadramaculatus. We tested whether there was a difference in parasite infection between this salamander and its sympatric, cryptic congener, Desmognathus folkertsi, in northern Georgia. Whereas larval D. quadramaculatus had a prevalence of 100% with intensities ranging from 18 to over 1,000, none of the D. folkertsi had visible metacercariae. These results indicate that M. oregonensis is more host-specific in salamander second intermediate hosts in the southern Appalachians than previously reported.

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
