Aeromonas Fish Pathogens
from: Aeromonas (Edited by: Joerg Graf). Caister Academic Press, U.K. (2015) Pages: 45-64.
An increasing range of aeromonads, including A. allosaccharophila, A. bestiarum, A. caviae, A. hydrophila, A. jandaei, A. salmonicida, A. schubertii, A. sobria biovar sobria and A. veronii biovar sobria, have become associated with disease of predominantly freshwater fish in most countries. The diseases caused include fin/tail rot and generalised septicaemias often with high mortality rates. Diagnosis has progressed from phenotypic and serological approaches to molecular methods, the latter of which may be extremely sensitive and specific. Pathogenicity mechanisms include surface associated, e.g. the surface (S) layer, diffusible, e.g. proteases, and subcellular components, including lipopolysaccharide and outer membrane proteins. Disease control has progressed from use of antimicrobial compounds to include vaccines, probiotics, immunostimulants and plant products read more ...
