The interactions between animal hosts and their associated microbiota can be studied at multiple spatial and conceptual scales, with each providing unique perspectives on the processes structuring host-microbe systems. Recently, zebrafish, Danio rerio, has emerged as a powerful model in which to study these interactions at many different scales. Controlled but simplified gnotobiotic experiments enable discovery of the molecules and cellular dynamics that shape host-microbe system development, whereas population level investigations of bacterial dispersal and transmission are beginning to reveal the processes shaping microbiota assembly across hosts. Here we review recent examples of these studies and discuss how the results can be integrated to better understand host-microbiota systems.
动物宿主与其相关微生物群之间的相互作用可以在多个空间和概念尺度上进行研究,每个尺度都为宿主-微生物系统的结构过程提供独特的视角。最近,斑马鱼(Danio rerio)作为一种强大的模型,已经可以在许多不同的尺度上研究这些相互作用。通过控制但简化的无菌实验,可以发现塑造宿主-微生物系统发育的分子和细胞动态,而对细菌扩散和传播的群体水平研究开始揭示塑造宿主间微生物组组装的过程。在这里,我们回顾了这些研究的最新实例,并讨论了如何整合这些结果以更好地理解宿主-微生物组系统。
