Nontypable group B streptococci isolated from human sources.
نویسنده
چکیده
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.

Antisera raised in rabbits against two nontypable group B streptococci, which were not agglutinable in a specific group B antiserum, were tested with acid extracts of 78 nontypable human group B streptococci. One antiserum (12351) reacted with 15 strains, and the other (7271) reacted with only 2 strains. Antiserum to Wilkinson's strain SS 1169 (NT 1) reacted with three strains. Antiserum agains...

A total of 898 group B streptococci isolated from a wide variety of human clinical sources from July 1967 through June 1972 were typed by the Lancefield precipitin test. Only 11% of the strains were nontypable. Twenty-six percent of the group B strains were from respiratory sources, 22% were from cerebrospinal fluid (CSF) and blood, 13% were from the female genital tract, 12% were urine specime...
