Serological relationships of type I antigens of group B streptococci.
Some of the complex antigenic relationships of type I group B streptococci from various clinical sources were defined by means of immunodiffusion, absorption, and precipitin tests. Three predominant types are described: Ia, Ib, and Ii. Methods for preparing antisera for differentiating type I strains are presented.
متن کاملType-specific Polysaccharide Antigens of Group B Streptococci
The type-specific antigen of Group B Type II streptococci has been prepared free of other known cell components. This antigen is a capsular polysaccharide containing D-galactose, D-glucose, N-acetyl-D-glucosamine, and a labile component which has not been chemically characterized. Extraction of Type II streptococci with cold TCA yielded this antigen which contained two serological determinants....
متن کاملExtracellular virulence factors of group B Streptococci.
Group B Streptococcus (GBS) is the leading cause of severe bacterial infections in human newborn infants. Advances in streptococcal molecular genetics and refinement of in vitro and in vivo model systems of GBS disease have led to the discovery and characterization of several extracellular virulence factors elaborated by this pathogen. This review summarizes our current understanding of GBS ext...
متن کاملIdentification of a highly encapsulated, genetically related group of invasive type III group B streptococci.
Type III group B streptococci (GBS) isolated from Tokyo and Salt Lake City were classified according to the similarity of HindIII and Sse83871 restriction digest patterns (RDPs) of bacterial DNA. The bacteria were clustered into three RDP types, with excellent correlation between subtyping based on the two enzymes. The majority (91%) of invasive isolates obtained from neonates were RDP type III...
متن کاملDemonstration of opsonic activity and in vivo protection against group B streptococci type III by Streptococcus pneumoniae type 14 antisera
The present studies demonstrate that antisera directed against Streptococcus pneumoniae type 14 is opsonic for group B streptococci type III in a neutrophile-mediated bactericidal assay. Specificity was demonstrated by the observations that group B streptococci type III and S. pneumoniae type 14 adsorbed the opsonic activity of anti-S. pneumoniae type 14 antisera. Group B streptococci strain 09...
