Abstract
A serious epdemic of P.crocea cultured in net cage in Ninde was broken out in srmmer,1999.Two strains isolated from the diseased fish were confirmed to be the pathogens of the epidemic by artificial infection tests.Detection on 44 kinds of bio chemical characteristics on 2 strains of pathogens isolated from P.crocea were done.According to the results and to Bergeys Mannual of Systematic Bacteriology(1984),strain ND-01 was Vibrio alginolyticus ,while strain ND-02 was V.parahaemolyticus . Meanwhile,the sensitivity of two strains to 50 kinds of antibiotic was detected.The results showed that 19 kinds of antibiotic had no inhibitory activity to strain ND-01,while strain ND-02 had resistance to 10 kinds of chemotherapeutants.Strain ND-01 was sensitive to Chloramphenicol and other 8 kinds of antibiotic,strain ND-02 was sensitive to 10 kinds of chemotherapeutants.
