Prevalence of Aeromonas salmonicida was studied in mature chum (Oncorhynchus keta), pink (O. gorbuscha), and masu salmon (O. musou) without signs of furunculosis. From September 1979 to November 1990, a total of 15,264 chum, pink and masu salmon were collected from 33 rivers. We isolated A. salmonic...
