Is coagulase test a microbiological test?
YES
What is a coagulase test used for?
Rabbit plasma, sometimes with EDTA added
Test used for the identification of Staphylococcus aureus?
staph. aureus test positive for catalase test and coagulase test consecutively
What are the general characteristics of staphylococcus Aureus?
Gram + coccus. Positive methanol test. Yellow on agar.
Is citrate test results for Staphylococcus aureus?
No, Catalase +ve, Coagulase +ve, Gram + cocci. Citrate test is usually used to differentiate members of the Family Enterobacteriaceae. Check Bergeys systematic bacteriology. 1980
Why is it important to use fresh cultures in a coagulase test?
Coagulase is a protein enzyme. It is important to use fresh cultures in a coagulase test because coagulase expression is highest during the log phase of growth.
Is coagulase test a microbiological test?
YES
What is the difference between widal slide test Antigen and widal tube test antigen?
widal slide is easier and it save time but widal tube test is not easy and it takes time.
What bacterial product does staphaurex test for?
Staphaurex is a rapid slide agglutination procedure for differentiating Staphylococci that possess coagulase and/or protein A. Particularly Staphylococcus aureus, from Staphylococci that possess neither of these factors.
What is a coagulase test used for?
Rabbit plasma, sometimes with EDTA added
Test used for the identification of Staphylococcus aureus?
staph. aureus test positive for catalase test and coagulase test consecutively
What is the difference between diagnostic test and proficiency test?
what is the difference between proffiency and diagnostic test
What is the difference between proficiency test and diagnostic test?
what is the difference between proffiency and diagnostic test
What is the difference between a test and a demonstration?
The difference between a test and a demonstration is that a test is to be taken and answered and a demonstration is to be demonstrated and be told to the class
What is a free coagulase and its significance?
Free coagulase is an extracellular toxin that reacts with a thrombin-like, thermostable substance known as coagulase-reacting factor (CRF) or serum factor. The reaction of coagulase and CRF will lead to the formation of coagulase-CRF complex where this complex indirectly changes frbrinogen to fibrin (clotting factor) and hence will form a fibrin clot. Furthermore, it is also use as the primary indicator of virulence among staphylococci. Its clinical significance is that when doing the coagulase tube test, the free coagulase will react with the plasma in the tube and hence convert the fribrinogen into fibrin which lead to fibrin clot formation in the tube. This is shown after one day of incubation of the tube, when the tube being invert, the plasma will not go down showing that it is clotted.
What is the principle behind the coagulase test?
in the coagulase test, normally a virulent staphylococcus is put into plasma. plasma contains the plasma protein fibrinogen. when fibrinogen is acted upon by a fibrinogenase, it is then converted to fibrin. fibrin has te ability to form clots. so in the case of staphylococcus aureus which has the enzyme coagulase also called fibrinogenase, the enzyme acts on the fibrinogen in plasma which is converted to fibrin hence the clots that are seen suspending in the solution after 4 hours.
