Introduction Multicellular organisms are surrounded by microbes that are critically important for their health and fitness. Pathogens drive infectious diseases that weaken or kill their hosts and have been at the forefront of microbiological research in the past century (Madigan et al., 2018). A more recent discovery, host-associated microbes are involved in complex interactions with each other and their host, ultimately driving many aspects of host physiology (McFall-Ngai et al., 2013).
