已查明,大多数致病微生物具有与人和动物组织抗原相似的多相抗原。许多研究者把这种抗原的生物学作用与细菌的毒力、自身免疫疾病的发生联系在一起。因此,研究免疫菌株的多相抗原是有意义的。 It has been found that most pathogenic microorganisms have multiphasic antigens similar to human and animal tissue antigens. Many researchers associate the biological role of this antigen with the virulence of bacteria and the development of autoimmune diseases. Therefore, it is meaningful to study the multiphasic antigens of immunized strains.
