New serotypes of group B streptococci isolated from human sources.
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...
متن کاملCharacterization of vaginal & rectal colonization with multiple serotypes of group B streptococci using multiple colony picks.
BACKGROUND & OBJECTIVES There is paucity of information on vaginal and rectal colonization with multiple serotypes of group B streptococci (GBS). As part of an ongoing cohort study evaluating the natural history of vaginal and rectal colonization by GBS, the colonization with multiple serotypes was studied in 102 non-pregnant women aged 18-30 yr. METHODS Up to ten separate colony picks of bet...
متن کاملSerotypes of group B streptococci in western Sweden and comparison with serotypes in two previous studies starting from 1988
BACKGROUND Group B Streptococci (GBS) are the most common neonatal pathogens and infect immunocompromised and elderly individuals. The species has 10 different serotypes. Serotypes have been studied in the south-west area of Sweden in 1988-1997 and 1998-2001. The aim of this study was to study serotypes in the same area from 2004 to 2009. METHODS Invasive GBS isolates were collected prospecti...
متن کاملSerotypes of group B meningococci.
Strains of group B meningococci isolated from cases of sporadic infection, epidemic infection, and from patients unassociated with clinical meningococcal infection have been examined by a serological typing technique. The majority of group B meningococci from clinical infections in the UK have serotype 2 antigen. Such strains were relatively uncommon among carriers who had no association with m...
متن کاملMolecular analysis of multiple isolates of the major serotypes of group B streptococci.
Serotyping of clinical isolates is a widely used technique for epidemiologic study of group B streptococcal infections. However, serotyping cannot definitively determine epidemiologically related or unrelated isolates. We investigated the use of restriction endonuclease analysis (REA) with both conventional agarose gel electrophoresis (AGE) and pulsed-field gel electrophoresis (PFGE) in 50 isol...
