The necromenic nematode has been frequently found in nests of the invasive European ant in coastal Maine, United States, and may contribute to ant mortality and collapse of colonies by transferring environmental bacteria. and several other bacterial species were found in the digestive tracts of nematodes harvested from collapsed ant colonies. , , and were collected from the hemolymph of nematode-infected wax moth () larvae. Virulence against waxworms varied by the site of origin of the nematodes. In adult nematodes, bacteria were highly concentrated in the digestive tract with none observed on the cuticle. In contrast, juveniles had more on the cuticle than in the digestive tract. Host species was the primary factor affecting bacterial community profiles, but sp. and sequences were shared across ants, nematodes, and nematode-exposed larvae.
在美国缅因州沿海地区，人们经常在入侵的欧洲蚂蚁巢穴中发现尸食性线虫，这种线虫可能通过传播环境细菌导致蚂蚁死亡和蚁群崩溃。从崩溃蚁群中采集的线虫消化道内发现了几种其他细菌物种。从受线虫感染的蜡螟（）幼虫血淋巴中收集了、和。线虫对蜡螟的毒力因线虫的起源地而异。在成年线虫中，细菌高度集中在消化道，角质层上未观察到细菌。相比之下，幼虫角质层上的细菌比消化道中的更多。宿主物种是影响细菌群落特征的主要因素，但、和序列在蚂蚁、线虫和暴露于线虫的幼虫中都有共享。
