Climatic and ecological factors can influence the parasite load of a host. Variation in rainfall, body size, and sex of the hosts may be related to the abundance of parasites. This study investigated the helminth fauna associated with a population of , together with the effect of host biology (sex, body size, and mass) and variation in rainfall regime on the abundance of helminths. Species of three groups of endoparasites were found (Nematoda, Cestoda, and Trematoda), with nematodes as the most representative taxa with eight species, prevalence of 63.2 %, mean intensity of 4.0 ± 0.58 (1 - 25), and mean abundance of 2.66 ± 0.44 (0 - 25). Nine helminth species are new host records for . . The nematode sp. had the highest prevalence (53.3 %). There was no signifi cant relationship between abundance of the trematode and host sex or season, although the abundance of this parasite increased significantly with host body size and mass, while abundance of nematodes was related to season and host mass. This study increases the knowledge about the diversity of helminth fauna associated with , revealing infection levels of hosts from northeastern Brazil.
气候和生态因素会影响宿主的寄生虫负荷。降雨量、宿主体型和性别的变化可能与寄生虫的丰度有关。本研究调查了与某一群体相关的蠕虫动物群，以及宿主生物学特征（性别、体型和体重）和降雨模式变化对蠕虫丰度的影响。发现了三类体内寄生虫（线虫纲、绦虫纲和吸虫纲）的物种，其中线虫是最具代表性的类群，有8个物种，感染率为63.2%，平均感染强度为4.0±0.58（1 - 25），平均丰度为2.66±0.44（0 - 25）。有9种蠕虫物种是……的新宿主记录。线虫……属的感染率最高（53.3%）。吸虫……的丰度与宿主性别或季节之间没有显著关系，尽管这种寄生虫的丰度随着宿主体型和体重的增加而显著增加，而线虫的丰度与季节和宿主体重有关。本研究增加了关于与……相关的蠕虫动物群多样性的知识，揭示了巴西东北部宿主的感染水平。
