Group B beta-hemolytic streptococci causing pharyngitis.
Group B beta-hemolytic streptococci were isolated from the throats of 49 of 1,110 patients who had pharyngitis. Compared with patients whose throat cultures were negative for beta-hemolytic streptococci, those harboring group B were more likely to have enlarged tonsils (P less than 0.001), exudate (P less than 0.02), and tender enlarged anterior cervical lymph nodes (P less than 0.01). Group B ...
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 کاملFatal infection associated with group C streptococci.
Serious infection caused by Lancefield group C streptococci is unusual in man. Two unrelated deaths associated with these organisms in a 55 year old woman who died after three days of diarrhoea and vomiting, and in a 65 old man who died after a week of non-specific symptoms, are presented. Post mortem examination showed septicaemia in the former and severe aortic stenosis with widespread septic...
متن کاملThe Virulence of Group C Hemolytic Streptococci of Animal Origin
A non-antigenic mucoid polysaccharide similar to that described by Kendall, Heidelberger, and Dawson was isolated from group C hemolytic streptococci. A simple method for its quantitative estimation is described. By means of this quantitative method, as well as by the direct isolation of the carbohydrates, the size and persistence of capsules in young cultures of various strains have been relat...
متن کاملLectins detecting group C streptococci.
Lectin of Wisteria floribunda specifically agglutinates group C streptococci. The reaction is strongly inhibited by N-acetyl-d-galactosamine, slightly by lactose, and not at all by galactose. The utility of the simple test of the lectin with group C streptococci is discussed.
