What does it mean to be coagulase positive?

What does it mean to be coagulase positive?

If ‘positive’ (e.g., the suspect colony is S. aureus), the plasma will coagulate, resulting in a clot (sometimes the clot is so pronounced, the liquid will completely solidify). If ‘negative’, the plasma remains a liquid. The negative result may be S.

What does Pseudomonas stutzeri cause?

Since that initial infection, P. stutzeri has been able to cause infections within individuals that have a variety of illnesses, including: endocarditis, infections of the bone, eye, skin or urinary tract, meningitis, pneumonia, arthritis, and several others.

What is Gram cocci positive?

Gram-positive cocci include Staphylococcus (catalase-positive), which grows clusters, and Streptococcus (catalase-negative), which grows in chains. The staphylococci further subdivide into coagulase-positive (S. aureus) and coagulase-negative (S. epidermidis and S.

Is Pseudomonas fluorescens an obligate Aerobe?

Pseudomonas fluorescens. Pseudomonas fluorescens is an obligate aerobe, gram negative bacillus. These bacteria are able to inhabit many environments, including: plants, soil, and water surfaces.

How did the coagulase results differ in respect to staph aureus vs Staph epidermidis?

Staphylococcus aureus produces free coagulase; Staphylococcus epidermidis does not.

Why is the coagulase test important?

The coagulase test is an important test that differentiates the species of the genus Staphylococci into two groups; Coagulase positive Staphylococci and Coagulase Negative Staphylococci.

What is the difference between Pseudomonas fluorescens and Pseudomonas aeruginosa?

Difference Between Pseudomonas aeruginosa and Pseudomonas fluorescens. The key difference between Pseudomonas aeruginosa and Pseudomonas fluorescens is that the P. aeruginosa is an opportunistic human pathogen while the P. fluorescens is not a human pathogen.

What is the significance of Pseudomonas fluorescens?

Certain members of the P. fluorescens have been shown to be potential agents for the biocontrol which suppress plant diseases by protecting the seeds and roots from fungal infection. They are known to enhance plant growth promotion and reduce severity of many fungal diseases (Hoffland et al. 1996.
