Abstract
The present study was done to determine whether so-called nontypable (NT) group B streptococci from human sources possess as yet unrecognized type antigens. Antisera were raised in rabbits against several NT strains and then tested with hydrochloric acid extracts of 53 NT group B streptococci. One serum was strain specific, another was nonspecific in that it contained only R-protein antibodies, and a third (NT1), although apparently type specific, reacted with only five strains. These results do not justify using NT1 serum in the group B typing system.
摘要
本研究旨在确定来自人类的所谓非分型（NT）B族链球菌是否具有尚未被识别的型抗原。用数株NT菌株免疫家兔制备抗血清，然后用53株NT B族链球菌的盐酸提取物进行检测。一种血清具有菌株特异性，另一种血清是非特异性的，因为它只含有R蛋白抗体，第三种血清（NT1）虽然显然具有型特异性，但仅与五株菌株发生反应。这些结果表明在B族分型系统中使用NT1血清并不合理。
