This study presents the helminth composition and parameters of infection by several species of nematodes in teiid lizards, Ameiva ameiva ameiva (Linnaeus, 1758), Cnemidophorus cryptus Cole and Dessauer, 1993, and Kentropyx calcarata Spix, 1825 from the Brazilian Amazonian Rainforest. The population of lizards studied were parasitized by 6 species of Phylum Nemata including: Spinicauda spinicauda (Olfers, 1919), Parapharyngodon alvarengai Freitas, 1957, Physaloptera sp. (adults), Physaloptera sp. (larvae), Piratuba digiticauda Lent and Freitas, 1941, and Anisakidae (larvae). The overall prevalence was 66.17% and the mean intensity of infection was 19.40 ± 25.48. The association between the body-length of lizards and the abundance and richness of parasitic nematodes was statistically significant only in Ameiva a. ameiva. A new host record is reported here with 1 specimen of the family Anasakidae in Ameiva a. ameiva. Both S. spinicauda and Physaloptera sp. represent new records from C. cryptus.
本研究展示了来自巴西亚马逊雨林的鞭尾蜥科蜥蜴（丽纹鞭尾蜥，1758年林奈命名；隐肢蜥，1993年科尔和德绍尔命名；尖吻蜥，1825年斯皮克斯命名）体内几种线虫的蠕虫组成及感染参数。所研究的蜥蜴种群被6种线虫寄生，包括：刺尾线虫，1919年奥尔弗斯命名；阿尔瓦伦加副咽线虫，1957年弗雷塔斯命名；泡翼线虫属（成虫）、泡翼线虫属（幼虫）、指尾皮拉线虫，1941年伦特和弗雷塔斯命名；异尖科线虫（幼虫）。总体感染率为66.17%，平均感染强度为19.40±25.48。仅在丽纹鞭尾蜥中，蜥蜴体长与寄生线虫的丰度和丰富度之间的关联具有统计学意义。本文报道了丽纹鞭尾蜥体内异尖科线虫1个标本这一新宿主记录。刺尾线虫和泡翼线虫属均为隐肢蜥的新记录。
