Abstract: Artificial infection with the S-1 & S-2 pathogenic strains of the carp bacterial septicemia and the S-3 & S-4 pathogenic strains of carp perforation disease succeeded. The artificial infected fish has the same symptom as the natural infected. And the bacteria with same characters were isolated from the artificial fish. The result shows these strains have strong pathogenicity to carp. According to morphology, cultural character, biochemistry reaction, these bacteria fit well to the aermonas hydophila standard strain. So the pathogens of the carp bacterial septicemia and the perforation disease are the same bacterium, that is aermonas hydophila.
