The ultrastructural morphology of the alimentary tract of the third-stage larvae of Litomosoides carinii (Nematoda: Filarioidea) is described. The oesophagus possesses the characteristic tri-radiate lumen and is lined by cuticle. Teh lumen of the oesophagus is tightly occluded anteriorly by particulate material and posteriorly at the oesophagointestional junction. Three glands are present in the glandular region, one dorsal and two subventral. These glands contain secretory granules with similar morphological and staining properties. The lumen of the intestine is ill-defined without microvilli and apparently non-functional. It is likely that the larvae feed via the transcuticular route.
描述了卡里尼丝虫（线虫纲：丝虫总科）第三期幼虫消化道的超微结构形态。食管具有特征性的三辐射状管腔，内衬角质层。食管管腔在前端被颗粒物质紧密阻塞，在食管与肠道交界处的后端也被阻塞。在腺体区域有三个腺体，一个背侧腺体和两个腹侧腺体。这些腺体含有具有相似形态和染色特性的分泌颗粒。肠道管腔不明确，没有微绒毛，显然无功能。幼虫可能通过经皮途径进食。
