摘要:

旨在为掌握新疆吐哈盆地三种荒漠蜥蜴胃肠道线虫种类及感染情况,对新疆岩蜥(Laudakia stoliczkana)、吐鲁番麻蜥(Eremias roborowskii)和叶城沙蜥(Phrynocephalus axillaris)共计127只蜥蜴进行胃肠道线虫检查,采用剖检法分离胃肠道线虫,进行形态学鉴定。使用卡方检验和单因素方差分析对三种不同荒漠蜥蜴性别间、头体长(snout-vent length,SVL)间、体重间的感染率和感染强度进行差异性分析。结果显示:三种荒漠蜥蜴胃肠道线虫总感染率为28.35%,新疆岩蜥感染率为100%,吐鲁番麻蜥感染率为27.59%,叶城沙蜥感染率为22.22%;新疆岩蜥胃肠道线虫感染率和感染强度极显著高于吐鲁番麻蜥和叶城沙蜥,其雄性感染强度显著高于雌性;较大体型的感染强度更高。基于虫种形态特征鉴定出三种优势虫种为泡翼科Abbreviata属线虫、咽齿科Spauligodon属线虫和咽齿科Parapharyngodon属线虫,均为中国新纪录属。本研究对新疆吐哈盆地三种荒漠蜥蜴胃肠道线虫进行感染情况调查及影响因素分析,不仅为新疆荒漠蜥蜴寄生虫多样性研究积累重要数据资料,还可为荒漠蜥蜴保护及开发利用提供重要理论支撑。

Abstract:

In order to understand the gastrointestinal nematode species and infections of three desert lizards in the Turpan-Hami Basin of Xinjiang, a total of 127 lizards of Laudakia stoliczkana, Eremias roborowskii and Phrynocephalus axillaris were examined for gastrointestinal nematodes using the dissection method to isolate gastrointestinal nematodes for morphological identification. Differential analyses of infection rates and intensity of infection among sexes, head and body lengths (Snout-vent length, SVL), and body weights of the three different desert lizards were performed using chi-square tests and one-way analysis of variance (ANOVA). The results showed that the total infection rate of gastrointestinal nematodes in the three desert lizards was 28.35%, with L. stoliczkana having an infection rate of 100%, E. roborowskii having an infection rate of 27.59%, and P. axillaris having an infection rate of 22.22%; the prevalence and intensity of gastrointestinal nematode infections in L. stoliczkana were significantly higher than those in E. roborowskii and P. axillaris, and the intensity of infection in males was significantly higher than that in females; the intensity of infection was higher in large-sized L. stoliczkana and P. axillaris. The three dominant species were identified as nematodes of the genus Abbreviata in the family Physalopteridae, nematodes of the genus Spauligodon in the family Pharyngodonidae, and nematodes of the genus Parapharyngodon in the family Pharyngodonidae, all of which are newly recorded genera in China. The present study investigated the infection status of the three species of gastrointestinal nematodes of desert lizards in the Turpan-Hami Basin of Xinjiang and analyzed their influencing factors. This study not only accumulates important data for the study of parasite diversity of desert lizards in Xinjiang but also provides important theoretical support for the conservation, development and utilization of desert lizards.
