1. Bound coagulase is part of the larger family of MSCRAMM. 2. Strains of this species were originally isolated from otters and are coagulase -positive. 3. Coagulase reacts with prothrombin in the blood.4. If the slide coagulase test is negative, a tube test should follow as a confirmation. 5. It is coagulase -negative and is probably a commensal organism on the skin of humans. 6. All species were once thought to be coagulase -positive, but this has since been disproven. 7. It is identitified as a species of coagulase -negative staphylococci ( CoNS ) using the coagulase test. 8. It is identitified as a species of coagulase-negative staphylococci ( CoNS ) using the coagulase test. 9. In the laboratory, it can give a positive slide-coagulase test but a negative tube-coagulase test. 10. In the laboratory, it can give a positive slide-coagulase test but a negative tube-coagulase test.
