Abstract

abstract: In June 2014, 30 marbled toads (Incilius marmoreus) from Oaxaca, Mexico were examined for helminths. We collected a total of 3,783 helminths belonging to 13 taxa: 4 digenean, 1 cestode, 1 acanthocephalan, and 7 nematoda. The nematode Physocephalus sp. was the most prevalent (63.3%) followed by Aplectana sp., which had the highest mean intensity (114.3) and mean abundance (63.8) that we recorded. The taxonomic composition of I. marmoreus mainly consists of generalist helminths, with nematodes being the predominant parasites found, confirming the terrestrial habits of this toad. The main route of helminth acquisition was ingestion of larvae and/or intermediate hosts, a process that also likely contributes to the high abundance of individuals in the toads. The knowledge of the helminth fauna associated to the 39 toad species distributed in Mexico is scarce and fragmentary, and our study presents results for only the second bufonid species studied in this region.

文章题目墨西哥新热带地区marmoreus的蠕虫区系(无尾目:蟾蜍科)

2014年6月，对墨西哥瓦哈卡州30只大理石纹蟾蜍(Incilius marmoreus)进行了蠕虫检测。共采集寄生虫3,783条，隶属于13个分类群:地沟虫4条，虫门1条，棘头虫1条，线虫7条。其中以大头虫(Physocephalus sp.)最常见(63.3%)，其次为Aplectana sp.，平均强度为114.3，平均丰度为63.8。其分类学组成以多面虫为主，以线虫为主，证实了该蟾蜍的陆栖习性。蠕虫获取的主要途径是吞食幼虫和/或中间寄主，这一过程也可能有助于蟾蜍个体的高丰度。关于分布在墨西哥的39种蟾蜍的蠕虫动物区系的知识是稀缺和零碎的，我们的研究只提供了该地区研究的第二种蟾蜍的结果。
