Aeromonas salmonicida was detected in the blood, kidney and spleen of rainbow trout within 2 min of immersion in a suspension containing 10 4 cells/ml. Uptake into fish was enhanced by culturing the pathogen in low levels of nutrient, i.e., 0.1% (w/v) brain heart infusion (BHI) broth and by the addition of latex particles to the bacterial suspensions. However, there was no apparent difference in the uptake of pathogenic or non‐pathogenic isolates. Moreover, the fish did not succumb to clinical signs of disease.
