Typing Group a Hemolytic Streptococci
Two methods of typing group A hemolytic streptococci have been described: slide agglutination and anti-M precipitin tests. The first, developed by Griffith (1), is more extensively used. I t has the distinct advantages of requiring small amounts of serum and culture, and of a quick reaction time when all conditions are favorable. I t has certain disadvantages: The granular growth of some strain...

متن کاملGrouping and detection of group B streptococci by immunofluorescence.
Forty-nine clinical isolates of group B streptococci (GBS) were correctly grouped from broth culture by the Fluoro-Kit immunofluorescence test. A further 82 beta-haemolytic streptococci of groups A, C, D, F, and G were tested and gave no cross-reactions. The test was simple to perform and gave clear results. The Fluoro-Kit reagents, however, failed to detect GBS in 21 (51%) of 41 smears of rect...
متن کاملIdentification of group B streptococci by immunofluorescence staining.
Gamma globulin fractions of rabbit antisera prepared with whole cell vaccines of group B types Ia, Ib, II, and III and labeled with fluorescein isothiocyanate stained group B streptococci type specifically. Type Ic cells, which contain the Ia polysaccharide antigen of type Ia and the Ic protein antigen of type Ib, were specifically stained by both Ia and Ib conjugates. A group B conjugate pool ...
متن کاملGrowth Media for Typing Group a Streptococci.
It is frequently not possible to type group A streptococei. Only 33% of group A streptococei from Nashville children in a recent study (Quinn and Martin, Am. J. Hyg. 73:193, 1961) were typable, and there have been years when as few as 5% could be typed. This study was designed to test one possible reason for failure to type certain strains of group A streptococci, namely, inadequacy of growth m...
