Journal of clinical microbiology, 1977•Am Soc MicrobiolThe 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 …
