Homarus americanus carapace bacteriome associated with impoundment shell disease

American lobster (Homarus americanus) impoundment shell disease (ISD) is a distinct pathological condition from the more well-known epizootic shell disease, but it is common observed at low prevalences in American lobsters held overwinter in tidal pounds and significantly reduces their economic value. The ISD was originally described in 1937, however its pathological agents are still unclear. The main goal of this study was to characterize the bacterial microbiome associated with ISD in Canadian lobsters. Animals were collected from a pound in southwest Nova Scotia, Canada, and the full 16S rRNA gene from lesion and healthy carapace areas of asymptomatic (As), moderately symptomatic (MS) and severely symptomatic (SS) animals was sequenced.
