从水稻细菌性条斑病菌的细胞中抽提出两大类抗原物质。一类是黄色的蛋白质，其中某些抗原成分为水稻白叶枯病菌和５个野油菜黄单胞菌致病变种的共同抗原，是非特异的；另一类是白色的蛋白质，是特异的，其相对应的抗血清在琼脂双扩散试验中，与来自不同省、区的水稻细菌性条斑病菌稳定地形成２条清晰的沉淀带，而与水稻白叶枯病菌和５个野油菜黄单胞菌致病变种不起反应。 Two types of antigenic substances have been extracted from the cells of rice bacterial leaf spot disease. One is the yellow protein, some of which are the common antigens of the bacterial pathogens of X. oryzae and five wild Xanthomonas campestris, nonspecific; the other is a white protein that is specific, The corresponding antiserum stably formed two clear sedimentary bands in the agar double diffusion test with the rice bacterial leaf stool pathogens from different provinces and regions, Cytomegalic strains can not react.
