The characteristics of six strains of Flavobacterium branchiophila , isolated from coldwater fishes with bacterial gill disease, were determined and compared by both agglutination and precipitation tests. The bacterial strains used in this study were isolated in Japan (3 isolates), USA (2 isolates), and Hungary (1 isolate). All of the strains were identical in physiological characteristics, except for slight differences in temperature and salinity tolerances. They possessed common antigens; however, the Japanese strains possessed serological differences from both USA and Hungarian strains. The results of the precipitation test identified one antigen specific for Japanese strains and two antigens specific for both USA and Hungarian strains.
