Comparisons of mutualistic and pathogenic relationships are necessary to decipher the common language of microorganism-host interactions, as well as the subtle differences in dialect that distinguish types of symbiosis. One avenue towards making such comparisons is to study a single organism that speaks both dialects, such as the gamma-proteobacterium Xenorhabdus nematophila. X. nematophila inhabits and influences the lives of two host animals, helping one to reproduce optimally while killing the other.
比较互利共生和致病关系对于解读微生物与宿主相互作用的通用语言以及区分共生类型的方言细微差异是必要的。进行此类比较的一条途径是研究一种能说两种方言的单一生物体，比如γ-变形菌嗜线虫致病杆菌。嗜线虫致病杆菌栖息于两种宿主动物并影响它们的生活，帮助其中一种最佳地繁殖，同时杀死另一种。
