Two Serological Types of Group B Hemolytic Streptococci with Related, but Not Identical, Type-specific Substances
1. Among group B hemolytic streptococci one serological type previously described as homogeneous has been shown, instead, to contain two closely related types, distinguishable by reciprocal absorption experiments. These streptococci are designated Types Ia and Ib. 2. Homologous organisms in each case absorb all antibodies from their respective antisera, while organisms of the heterologous relat...
متن کاملGroup 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 کاملThe role of b-hemolytic streptococci group B and anearobic infections in preterm premature rupture of membrane
preterm premature rupture of membrane(PPROM)is one of the serious problems during pregnancy.the aim of this study was to determine the probable relation between group B streptococal and anaerobic infections and PPROM.for this porpust 100 pregnant women with preterm rupture of membrane were selected.in the case group the prevalence of B-hemolytic streptococcal and anaerobic microorganisms was de...
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 کاملThe Serological Typing of Hemolytic Streptococci
The relationships among the hemolytic streptococci have been greatly clarified by the fundamental work of Lancefield (1). She has shown that these organisms may be classified into groups on the basis of a precipitin reaction and ample evidence has accumulated (2, 3) to show that almost all human infections are caused by members of her Group A. Strains of the groups from B to K are responsible f...
