A bacteriological examination of internal organs of diseased eels cultured in the Yoshida Region showed that the apparent incidence of eels infected with bacterial pathogens depended on the organs examined. A total of 96 eels carried pathogens such as Aeromonas hydrophila, Edwardsiela tarda and Pseudomonas anguilliseptica in heart (blood), spleen, liver or kidney. The incidence of eels with these bacteria was 77% in heart (blood), 84% in spleen, 89% in liver and 94% in kidney (Table 1).
