The effect of antimicrobial treatment upon the gill bacteriome of Atlantic salmon (Salmo salar L.) and progression of Amoebic Gill Disease (AGD) in vivo
Branchial surfaces of finfish species contain a microbial layer rich in commensal bacteria which can provide protection through competitive colonization and production of antimicrobial products. Upon disturbance or compromise, pathogenic microbiota may opportunistically infiltrate this protective ba...

Branchial surfaces of finfish species contain a microbial layer rich in commensal bacteria which can provide protection through competitive colonization and production of antimicrobial products.
