Prevalence of larval nematodes (Physocephalus sp., Spirurida, Spirocercidae) and associated cysts are reported from the blue spiny lizard, Sceloporus serrifer, from Texas (USA). Prevalence of infection was 29%, with seven of 24 animals infected. Larvae were found in gastric submucosal and occasionally mucosal cysts with a mean (+/- SE) of 287 +/- 9.04 microns in diameter. The nematodes evoked a chronic granulomatous response including cyst formation with focal destruction of gastric glands. Cysts resolved into areas of fibrosis. Sceloporus serrifer is a new host record for Physocephalus sp.
据报道，在美国得克萨斯州的蓝刺蜥（Sceloporus serrifer）体内发现了幼虫线虫（Physocephalus sp.，旋尾目，旋尾科）及相关囊肿。感染率为29%，24只动物中有7只被感染。幼虫存在于胃黏膜下层，偶尔也见于黏膜囊肿中，直径平均（±标准误）为287±9.04微米。这些线虫引发了慢性肉芽肿反应，包括囊肿形成以及胃腺的局灶性破坏。囊肿最终形成纤维化区域。蓝刺蜥是Physocephalus sp.的新宿主记录。
