Reclamation of streptococcal cells for reuse in adsorption of antisera.
One of the major problems in the production of diagnostic antisera for the specific Griffith types of Lancefield Group A hemolytic streptococci is the accumulation of sufficient volumes of cells for adsorption processes. To minimize this problem a procedure was developed for the reclamation and reuse of the adsorption cells. The technique is as follows: Packed cells, after use for adsorption, a...
متن کاملBacteriocin typing of streptococcal isolates from endocarditis.
A typing system based on bacteriocin production and sensitivity for Streptococcus sanguis strains was devised. Bacteriocin producer strains were grown (37degrees C) anaerobically on brain heart infusion-yeast extract agar for 18 h. Bacteriocin indicator strains were suspended to molten brain heart infusion-yeast extract agar and then overlayed onto the producer strain. After an additional 18 to...
متن کاملThe Inhibition of Streptococcal Desoxyribonuclease by Rabbit and Human Antisera
Rabbit antisera against partially purified streptococcal desoxyribonuclease inhibit the action of the enzyme on its substrate. The activity of pancreatic desoxyribonuclease is not affected by these antisera. Similarly antibody against pancreatic nuclease does not inhibit the streptococcal enzyme. Certain patients develop inhibitory antibody to streptococcal desoxyribonuclease following streptoc...
متن کاملTyping of pneumococci by using 12 pooled antisera.
A new simplified chessboard system for typing of Streptococcus pneumoniae is described. It is intended for typing or grouping of 90 to 95% of the pneumococcal strains most commonly isolated from blood or cerebrospinal fluid and is based on 12 pooled diagnostic antisera, each reacting with 7 to 11 single types, together covering the 23 different vaccine-related types as well as 25 other cross-re...
متن کاملSuperantigenicity of streptococcal M protein
M proteins that define the serotypes of group A streptococci are powerful blastogens for human T lymphocytes. The mechanism by which they activate T cells was investigated and compared with the conventional T cell mitogen phytohemagglutinin, and the known superantigen staphylococcal enterotoxin B. Although major histocompatibility complex (MHC) class II molecules are required for presentation, ...
