Biological Properties of Cell Wall Mucopeptide of Hemolytic Streptococci
نویسندگان
چکیده
Several of the toxic properties of streptococcal mucopeptide have been studied in detail. Intravenous injection of as little as 1 microg of mucopeptide, solubilized by ultrasonic treatment, elicits a reproducible febrile response. Rabbits which are made tolerant to Escherichia coli endotoxin are only partially tolerant to the subsequent injection of streptococcal mucopeptide. Soluble mucopeptide was successfully employed to prepare and provoke the localized Shwartzman reaction. Intravenous injection of 80 microg of solubilized mucopeptide leads to diffuse cellular infiltration as well as focal areas of myocardial necrosis, surrounded by inflammatory cells.

Immunochemical Studies on the Specific Carbohydrate of Group G Streptococci
Group G hemolytic streptococcal cell walls which have been treated with trypsin are composed of a group-specific polysaccharide moiety and a mucopeptide matrix. The mucopeptide contains N-acetylglucosamine, N-acetylmuramic acid, alanine, glutamic acid, lysine, and glycine, a composition similar to that of other groups of streptococci. The Group G carbohydrate is composed of rhamnose, N-acetylga...
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 کاملEnhanced Resistance to Streptococcal Infection Induced in Mice by Cell Wall Mucopeptide
The streptococcal cell wall mucopeptide when injected into mice either intraperitoneally or intravenously enhances the resitance to subsequent challenge with virulent Group A streptococci. Rabbits which are injected intravenously with solubilized mucopeptide develop a fever response which has a resemblance to that achieved with endotoxin. Mice which survive 6 to 7 weeks after challenge with vir...
متن کاملStudies on the Chemical Structure of the Streptococcal Cell Wall
The trypsinized cell walls of Group C streptococci contain two components, the group-specific carbohydrate and a mucopeptide polymer. Hot formamide extraction of Group C cell walls results in a soluble group-specific carbohydrate fraction and an insoluble mucopeptide residue. This mucopeptide, similar in composition to that of Groups A and A-variant streptococci, contains N-acetylglucosamine, N...
متن کاملAntigenic Relationships between Groups B and G Streptococci
Trypsinized cell walls of Group B hemolytic streptococci are composed of a group-specific carbohydrate and mucopeptide. The carbohydrate extracted with hot formamide is composed of rhamnose, N-acetylglucosamine, and galactose. Quantitative precipitin inhibition studies have shown that L rhamose is the significant component of the antigenic determinant. The cross-reactivity between B and G carbo...
