Coagulase: Coagulase is an
enzyme produced by Staphylococcus aureus that converts fibrinogen
to fibrin. In the laboratory, it is used to distinguish between
different types of Staphylococci isolates. Coagulase negativity excludes
S. aureus. S. aureus is coagulase-positive.
Slide coagulase test: The slide Coagulase test
detects bound coagulase (clumping factor). This type of coagulase is
attached ot the bacterial cell walls (surface). This test is usually
performed on a glass slide.
