An in vivo typing system for studying the immunological relationship of gonococcal strains was established. Nine gonococcal strains of proven virulence for guinea pig subcutaneous chambers were selected, and these isolates were used to immunize groups of guinea pigs that were subsequently cross-challenged with graduated numbers of gonococci from these isolates. Resistance to infection was determined by culture of fluid from challenged chambers; results were expressed as the median dose, in colony-forming units, of gonococci required to produce infection in each group of immunized guinea pigs. This information was then used to develop immunotypes of gonococci based on the cross-protection results obtained. Four cross-protecting immunotypes were established from the preliminary nine strains tested.
建立了一种用于研究淋球菌菌株免疫关系的体内分型系统。选择了9株经证实对豚鼠皮下腔具有毒力的淋球菌菌株,并用这些分离株免疫几组豚鼠,随后用来自这些分离株的不同数量的淋球菌对其进行交叉攻击。通过对受攻击腔室的液体进行培养来确定对感染的抵抗力;结果以每组免疫豚鼠产生感染所需的淋球菌菌落形成单位的中位数剂量表示。然后根据获得的交叉保护结果,利用这些信息开发淋球菌免疫型。从初步测试的9株菌株中建立了4种交叉保护免疫型。
