The prevalence and intensity of nematodes from the stomach and the prevalence of nematodes in the oral cavity were recorded in the frillneck lizard, Chlamydosaurus kingii, in Kakadu National Park (Australia) between 1991 and 1994, in order to determine whether or not a seasonal pattern was evident. Seven species were recorded; Strongyluris paronai, Skrjabinopatera goldmanae, Abbreviata confusa, Abbreviata anomala, Physalopteroides filicauda, Kreisiella sp. and a species of Trichostrongyloidea. Only S. paronai showed a seasonal pattern. Only larval S. paronai occurred in stomach samples and larvae of this species occurred seasonally in the oral cavity of C. kingii, substantiating earlier findings that this genus migrates within the host. The occurrence of S. paronai in the oral cavity coincided with the highest prevalence and intensity of S. paronai in stomach samples. This shows a previously unrecorded aspect in the life cycle of this nematode species. Prevalence of S. paronai was positively correlated with ambient temperature which is highest in the months preceding the monsoonal rains, and coincides with an increase in field metabolic rate and general activity of the host.
1991年至1994年间，为了确定是否存在明显的季节性模式，在澳大利亚卡卡杜国家公园对皱褶蜥（Chlamydosaurus kingii）胃内线虫的流行率和感染强度以及口腔内线虫的流行情况进行了记录。共记录到7个物种，分别是：帕氏强尾线虫（Strongyluris paronai）、戈氏斯克里亚宾线虫（Skrjabinopatera goldmanae）、混淆短体线虫（Abbreviata confusa）、异形短体线虫（Abbreviata anomala）、丝状拟泡翼线虫（Physalopteroides filicauda）、克氏线虫（Kreisiella sp.）和一种毛圆科线虫。只有帕氏强尾线虫呈现出季节性模式。胃样本中仅出现帕氏强尾线虫的幼虫，且该物种的幼虫在皱褶蜥口腔中呈季节性出现，证实了该属线虫在宿主体内迁移的早期研究结果。帕氏强尾线虫在口腔中的出现与胃样本中该线虫的最高流行率和感染强度相一致。这显示了该线虫物种生命周期中一个以前未被记录的方面。帕氏强尾线虫的流行率与环境温度呈正相关，环境温度在季风降雨前几个月最高，且与宿主的野外代谢率和一般活动增加相吻合。
