Using specific immunostaining of Western blots, the in vivo expression of several putative virulence factors of Aeromonas salmonicida subsp. salmonicida was demonstrated in infected muscle tissue of Atlantic salmon and rainbow trout. Three virulent isolates of A. salmonicida were used. One isolate was chosen because in vitro it was apparently a non-producer of the 70-kDa serine protease. Infected furuncle tissue was centrifuged and samples of the pellet and supernatant probed for evidence that the components of interest were bacterial cell-associated or secreted. The A-protein was detected in pelleted furuncle material but not in the supernatant. Lipopolysaccharide, both high and low molecular mass, was present in the pellet but only high molecular mass lipopolysaccharide was detected in the furuncle supernatant. Iron-regulated outer membrane proteins were detected in the furuncle pellet. The 70-kDa serine protease was detected in the furuncle supernatant of both protease-producing strains. However, whilst the protease-deficient isolate was demonstrated to produce low levels of the 70-kDa protease when grown in vitro under iron restricted conditions, none could be detected in vivo.
