A tubular or sac-like structure with a well defined lumen which occasionally contained parasites was found in the outer muscle wall of the small and large intestine in 32 out of 40 male and 35 of 40 female marsupial mice of the two species, Antechinus swainsonii and Antechinus stuartii (Macleay). A similar structure was also found in the muscle layers of the stomach in 5 marsupial mice of both species. The cellular matrix of the structure appeared to be composed of randomly organized macrophage-like cells and in one case there was evidence of an inflammatory reaction to parasites within the lumen. The origin of this tube is either vestigial or the result of reactive changes.
在两种袋鼬（斯氏袋鼬和史氏袋鼬）的40只雄性袋鼬小鼠中的32只以及40只雌性袋鼬小鼠中的35只的小肠和大肠外肌层中，发现了一种管状或囊状结构，其管腔清晰，偶尔含有寄生虫。在两种袋鼬的5只袋鼬小鼠的胃肌层中也发现了类似结构。该结构的细胞基质似乎由随机排列的巨噬细胞样细胞组成，在一个案例中，有证据表明管腔内对寄生虫有炎症反应。这种管道的起源要么是退化的，要么是反应性变化的结果。
