24. Assembly of Gut Microbial Communities in Freshwater Fish and Their Roles in Fish Condition
Abstract : Animal hosts provide associated microorganisms with suitable ecological niches in their intestines. Microbes help their hosts to digest food, protect against pathogens, and influence the host’s metabolisms. Compositional variation of gut microbial communities is common among hosts, and may affect the health status of hosts. READ MORE
