两种海洋蛀木等足类动物（三斑蛀木水虱和光背蛀木水虱）以及一种陆生蛀木等足类动物（鼠妇）和一种栖木端足类动物（凿船虫）的消化道没有微生物。用扫描电子显微镜对整个消化道进行检查，未发现微生物。相比之下，这些甲壳类动物的外骨骼表面有密集的细菌群落。正如所料，对白蚁后肠的观察显示出肠道微生物群落具有多样性。
Two marine [Limnoria tripunctata and L. lignorum] and 1 terrestrial wood-boring isopod [Oniscus asellus] spp. and 1 wood-inhabiting amphipod [Chelura terebrans] spp. maintain a digestive tract free of microorganisms. Digestive tracts examined in toto with the scanning electron microscope were devoid of microorganisms. In contrast, the outer exoskeleton surfaces of these crustaceans supported a dense bacterial flora. Observations of the hindgut of termites revealed a diverse gut microflora as expected.
