Comparative study of the hemolymph microbiome between live and recently dead American lobsters Homarus americanus

Lobsters and other crustaceans do not have sterile hemolymph. Despite this, little is known about the microbiome in hemolymph of lobster Homarus americanus . The purpose this study was to characterize lobsters. lobsters were part a larger on effect temperature epizootic shell disease, several died during course study, providing an opportunity examine differences microbiomes between live recently dead (1-24 h) animals. different from those animals both tank which had been held. more diverse suite bacteria than dominant taxa belonged Flavobacteriaceae Rhodobacteraceae , whereas Vibrionaceae Enterobacteriaceae predominant Although aquarium overlapped with microbiomes, there less overlap lower abundance comparison Previous studies reporting digestive tract suggested that invaded via gut. Our suggests abundant originate milieu comprise rich, natural, or native background bacterial constituents.
