Outline of Final Research Achievements

To clarify the pathogenic mechanism caused by oral administration of fish pathogenic bacteria via the rotifer Brachionus plicatilis in larval fish, that the present study investigated the relationship between the bacteria and B. plicatilis. The bacteria strains, Aeromonas hydrophila, Edwardsiella tarda, Photobacterium damuselae subsp. piscicida, Pseudomonas plecoglossicida, Vibrio anguillarum and Vibrio ichthyoenteri, used at this study were selected by Pulsed-field Gel Electrophoresis genotyping method. The results from the addition of the bacteria into the culture of B. plicatilis showed that 1.0E+4 cells / ml of the bacteria did not affect their life span, fecundity, and hatching rate of amictic eggs, and an individual rotifer contained 3.67E+2 CFU of bacteria in their intestine.
