Maintaining the high overall health of farmed animals is a central tenant of their well-being and care.Intense animal crowding in aquaculture promotes animal morbidity especially in the absence of straightforward methods for monitoring their health.Here, we used 12n/1200 wella bacterial 16S ribosomal RNA gene sequencing to measure bacterial population dynamics during P.salmonis infection.We observed a complex bacterial community consisting of a previously undescribed core pathobiome.

Notably, we detected Aliivibrio wodanis peppermint smoothie hibiscus and Tenacibaculum dicentrarchi on the skin ulcers of salmon infected with P.salmonis, while Vibrio spp.were enriched on infected gills.The prevalence of these co-occurring networks indicated that coinfection with other pathogens may enhance P.salmonis pathogenicity.
