The pathogenicities of 8 strains of Xanthomonas oryzae (Uyeda et Ishiyama) Dowson., which causes the bacterial leaf blight of rice plant were investigated by the method of pinbundle inoculation on leaves of rice seedlings. As a result, we confirmed that they showed various grades of pathogenic activity in every strain. The pathogenic coefficient differed from 13,7 to 0. Next, the susceptibilities of the 8 strains to some antibiotics were studied by cup method, paper-disk method and agar streak-dilution method. Great difference was observed in the susceptibilities to streptomycin sulfate and dihydrostreptomycin sulfate but little difference was found in penicillin G potassium salt, cellocidin, Chloramphenicol and other 7 antibiotics regardless of their pathogenicities.
