Staphylococcus aureus Biochemical Tests in Hindi | Catalase | Coagulase | Basic Science Series Hindi
Catalase enzyme,
Hydrogen peroxide (H2O2),
3% H2O2 on to the slide + Bacterial colony = rapid evolution of oxygen,
Staphylococcus aureus strains are coagulase-positive
Bacterial Colony + Plasma
Free coagulase and bound coagulase
Slide and tube coagulase test
Visible Clumping Positive Result
For some strains of S. aureus tube test is better
Pathogenic and nonpathogenic Staphylococcus are catalase-positive,
Streptococcus and Enterococcus are catalase-negative,
