摘要
INTRODUCTION The interaction between the host and host-associated microbial communities has been an area of increasing interest during recent decades.In most animal species,microflora is known to inhabit the gut,surface or surroundings(Dillon&Dillon 2004;Engel&Moran 2013;Kovatcheva-Datchary et al.2013).The microflora encompasses a range of microbial relationships,including pathogenic,obligately mutualistic and commensal relationships.During the past few decades,beneficial microorganisms have received much attention due to a myriad of mutualistic effects(e.g.modifying a nutrient-poor diet,protecting the host from parasites or pathogens,affecting the mating and breeding of hosts,and producing insect pheromones).Such studies have aided our understanding of the diversification and evolutionary success of animals(Flórez et al.2015;Paniagua Voirol et al.2018).Furthermore,technological applications have been identified:for example,efficient microbial cellulases from termites are presently being used in industrial processes(Scharf&Tartar 2008).
