Staphylococcus epidermidis is a Gram-positive bacterium that colonizes human skin and mucous membranes as a saprophage. The bacterium is not pathogenic to humans with intact immune systems. However, it can colonize polymeric plastic surfaces of implanted devices, such as catheters and artificial heart valves, forming a biofilm and causing the most serious nosocomial infections.

Coagulase test

Definition – What is the coagulase test? A coagulase test is performed to detect bacteria. Bacteria from the group of staphylococci can be distinguished by the so-called clumping factor. There are coagulase-positive staphylococci (Staphylococcus aureus) and coagulase-negative staphylococci (Staphylococcus epidermidis). The test is usually performed in a laboratory. The detection allows the therapy to be … Coagulase test

Evaluation | Coagulase test

Evaluation The evaluation depends on the formation of lumps, the so-called agglutination. If the formation of lumps occurs after the plasma and bacterium have been mixed on the slide or the test tube, the test is positive and it is a coagulase-positive Staphylococcus bacterium. If no lumps are formed but a milky cloud without agglutinates, … Evaluation | Coagulase test
