Preparation of protoplasts of group H streptococci (Streptococcus sanguis).
Stable protoplasts of several strains of group H streptococci (Streptococcus sanguis) can be prepared by use of group C streptococcal phage-associated lysin in the presence of 30% raffinose. Sucrose cannot be substituted for raffinose. Protoplast formation did not require the addition of Mg2+; however, this cation enhanced their stability. Some other strains, also presumptive group H streptococ...
متن کاملAntigenic determinant of the Lancefield group H antigen of Streptococcus sanguis.
Previous studies indicated that the teichoic acid isolated from strains of Streptococcus sanguis was group specific and defined the Lancefield group H streptococci. To determine the specific antigenic determinants, the antigen was extracted from a group H streptococcus (ATCC 903) by the phenol-water method and purified by column chromatography. The isolated antigen had a glycerol/phosphate/gluc...
متن کاملRelationship of the cell wall composition of group H streptococci and Streptococcus sanguis to their serological properties.
Previous studies indicated the a antigen was widely distributed among strains of Streptococcus sanguis and the group H streptococci. The cell walls of strains containing this antigen had moderate to large quantities of rhamnose, small amounts of phosphorus, and little to no ribitol. The molar ratios of the peptidoglycan amino acids and hexosamines suggested a di-alanyl cross bridge. The homogen...
متن کاملLung abscesses in 2 patients with Lancefield group F streptococci (Streptococcus milleri group).
Lung abscess presents as a circumscribed accumulation of pus in the lungs, which is more common in patients predisposed to aspiration, immunosuppressed patients, and patients with chronic lung disease, malignancies, or diabetes mellitus.1 Lung abscess is also associated with dental caries, alcohol abuse, and uncontrolled epilepsy. Many reports associate lung abscess with the presence of anaerob...
متن کاملSerological Relationships among and between the Streptococci and Pneumococci
Using the complement fixation reaction with whole bacterial solutions as antigens, it has been possible to confirm the existence, within the non-hemolytic streptococcus family, of two great groups. One of these groups, that which may be designated as of the left side, is related in an orderly way to the hemolytic streptococci; the other of the right side, is similarly related to the entire pneu...
