Rabbit Coagulase Plasma is an essential reagent in microbiology, widely used to detect coagulase enzyme activity in Staphylococcus aureus, a key pathogen responsible for various infections. The test differentiates coagulase-positive species like S. aureus from coagulase-negative staphylococci (CoNS), aiding in precise microbial identification.
The test is based on the ability of coagulase-positive staphylococci to clot plasma. The enzyme coagulase converts fibrinogen in plasma into fibrin, causing visible clot formation. The two main methods used are:
✅ Slide Test (Bound Coagulase Test) – Detects bound coagulase on the bacterial surface. A clumping reaction indicates a positive result.
✅ Tube Test (Free Coagulase Test) – Identifies free coagulase by incubating bacteria with Rabbit Coagulase Plasma; clot formation within 4 to 24 hours confirms a positive result.
🔬 Accurate Staphylococcus aureus Identification – Differentiates pathogenic S. aureus from less harmful CoNS.
⚕️ Clinical Significance – Helps diagnose skin infections, pneumonia, and bloodstream infections caused by S. aureus.
📊 Food Safety & Quality Control – Used in food microbiology to detect contamination by coagulase-positive staphylococci.
With the rise of methicillin-resistant Staphylococcus aureus (MRSA), rapid and accurate identification using Rabbit Coagulase Plasma is crucial in microbiology labs. Proper controls, incubation times, and interpretation of results ensure test reliability.
Rabbit Coagulase Plasma remains a gold standard in bacterial diagnostics, enabling microbiologists to quickly identify coagulase-positive Staphylococcus aureus for effective treatment and infection control. Its role in clinical and food microbiology makes it an indispensable tool for modern laboratories.
