Purification of staphylococcal coagulase.
Correlation between the pathogenicity of certain staphylococci and their ability to produce coagulase has led to extensive studies of the clotting enzyme. Walston (1935) precipitated the clotting substance from cell-free filtrates of appropriate staphylococcal cultures by the use of ethanol, acetic acid, or ammonium sulfate. Walker et al. (1948) partially purified staphylocoagulase by repeated ...
متن کاملStaphylococcal coagulase; mode of action and antigenicity.
Different strains of staphylococci vary in ability to produce free coagulase. Methods are given for the selection of suitable strains and for the production and concentration of coagulase from one of them. Of animal plasmas examined, cow, sheep, dog, guinea-pig and mouse showed a relative deficiency in coagulase activator, while plasma of man, monkey, horse, cat, pig, fowl and rabbit contained ...
متن کاملRapid Method of Determining Coagulase Activity during Staphylococcal Bacteriophage Typing.
The plate test, a modification of the slide test described by Cadness-Graves was developed for the rapid identification of coagulase-positive staphylococci in conjunction with bacteriophage typing. An evaluation of 1,145 cultures by three coagulase-determination methods, the slide, tube, and plate tests, indicates that the plate test is as accurate as the slide tests, and the plate test agrees ...
متن کاملCoagulase-negative staphylococcal peritonitis: outcomes of cephalosporin-resistant strains.
Peritoneal dialysis (PD) peritonitis and subsequent relapses are undesirable complications for patients requiring home peritoneal dialysis. Coagulase-negative staphylococci (CoNS) remain a common cause of peritonitis. Strains of CoNS are emerging that are resistant to cephalosporins. It has been suggested that, if sensitivity testing shows resistance to cephalosporin but the patient is improvin...
متن کاملIncreasing Incidence Of Coagulase - Negative Staphylococcal Sepsis - An Emerging Challenges
IntroductionCoagulase negative Staphylococcus (CoNS), being a part of the commensal flora, have long remained neglected as mere contaminants till their recently reported increased rate of isolation, evidenced their potential as nosocomial pathogens. Treatment is difficult due to confusion in pathogenecity and multi-drug resistance. Aim of the study was to to identify the different species of Co...
