Pyogenic streptococci--danger of re-emerging pathogens.
Beta-hemolytic, pyogenic streptococci are classified according to type of major surface antigen into A (Streptococcus pyogenes), B (Streptococcus agalactiae), C (multiple species including Streptococcus dysagalactiae) and G (multiple species including Streptococcus canis) Lancefield groups. Group A Streptococcus causes each year hundreds of thousands deaths globally as a result of infections an...
متن کاملCorrelation between ribosomal DNA polymorphism and electrophoretic enzyme polymorphism in Yersinia.
Ribosomal DNA (rDNA) polymorphism was compared with electrophoretic enzyme polymorphism for the intra- and interspecies differentiation of Yersinia enterocolitica, Y. pseudotuberculosis, Y. intermedia, Y. aldovae, Y. frederiksenii and Y. kristensenii. DNA from 90 strains previously classified into six zymotypes (Y. enterocolitica and Y. frederiksenii) and into distinct enzyme electrophoretic pa...
متن کاملErythrocyte glutathione S-transferase. Electrophoretic identification of two enzyme forms.
Starch-gel electrophoresis was used to demonstrate two forms of glutathione S-transferase in human erythrocytes. Whereas considerable inter-individual differences in enzyme activity and electrophoretic patterns were detected, intra-individual differences were small.
متن کاملTyping 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 کاملSpecies identification of oral viridans streptococci by restriction fragment polymorphism analysis of rRNA genes.
Oral streptococci formerly classified as Streptococcus sanguis have been divided into six genetic groups. Methods to identify those species by genotype are needed. This study compared restriction fragment polymorphisms of rRNA genes (ribotypes) for seven S. gordonii, three S. sanguis, four S. oralis, three S. mitis, one S. crista, and seven S. parasanguis strains classified in previous DNA hybr...
