Beta-hemolytic Streptococci with Group a and Type Ii Carbohydrate Antigens.
Jablon, James M. (National Children's Cardiac Hospital, Miami, Fla.), Betty Brust, and Milton S. Saslaw. beta-Hemolytic streptococci with group A and type II carbohydrate antigens. J. Bacteriol. 89:529-534. 1965.-Ten strains of beta-hemolytic streptococci with unusual somatic antigens were isolated from excised tonsils or throat cultures or both. Acid extracts of these strains reacted with comm...
متن کاملGroup-specific Carbohydrate of Group C-variant Hemolytic Streptococci
The trypsinized cell walls of Group C hemolytic streptococci are composed of the specific carbohydrate antigen and a mucopeptide matrix. Certain phage resistant strains of Group C streptococci, isolated from organisms which survive exposure to Group C bacteriophage also possess carbohydrate and mucopeptide fractions, but the carbohydrate gives a precipitin reaction with Group A-variant antiseru...
متن کاملType-specific Antigens, M and T, of Matt and Glossy Variants of Group a Hemolytic Streptococci
1. Two qualitatively different type-specific antigens, designated M and T, have been found present in matt variants of group A hemolytic streptococci, but only one of these, the T antigen, occurs in the degraded glossy variant. 2. The protein nature of the M antigen, present in matt variants only, has been demonstrated in previous work, but the chemical characteristics of the newly recognized a...
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...
