肠道的组成是由宿主遗传学，创始人的效果和宿主环境的复杂相互作用确定的。他们丰富的后肠微生物群落，杂食性饮食和群居的生活方式。 Periplaneta Americana的同种异体实验室种群以及在14天的适应于共同的实验室环境之前和之后，我们的结果表明，我们的结果表明，这两种鸡的肠道微生物组都不同于物种和饲养环境。来自同一物种的实验室和野生捕获的蟑螂也表现出不同的肠道微生物组剖面。野生昆虫的种类很有趣，尽管实验室种植也会造成类似的微生物这两个物种的多样性都不会导致这些物种的肠道微生物组变得更加相似。
Gut microbiome composition is determined by a complex interplay of host genetics, founder’s effects, and host environment. We are using omnivorous cockroaches as a model to disentangle the relative contribution of these factors. Cockroaches are a useful model for host–gut microbiome interactions due to their rich hindgut microbial community, omnivorous diet, and gregarious lifestyle. In this study, we used 16S rRNA sequencing to compare the gut microbial community of allopatric laboratory populations of Periplaneta americana as well as sympatric, wild-caught populations of P. americana and Periplaneta fuliginosa, before and after a 14 day period of acclimatization to a common laboratory environment. Our results showed that the gut microbiome of cockroaches differed by both species and rearing environment. The gut microbiome from the sympatric population of wild-captured cockroaches showed strong separation based on host species. Laboratory-reared and wild-captured cockroaches from the same species also exhibited distinct gut microbiome profiles. Each group of cockroaches had a unique signature of differentially abundant uncharacterized taxa still present after laboratory cultivation. Transition to the laboratory environment resulted in decreased microbiome diversity for both species of wild-caught insects. Interestingly, although laboratory cultivation resulted in similar losses of microbial diversity for both species, it did not cause the gut microbiome of those species to become substantially more similar. These results demonstrate how competing factors impact the gut microbiome and highlight the need for a greater understanding of host–microbiome interactions.
