What does the enzyme coagulase do?
The coagulase enzyme activates prothrombin, which causes fibrin formation around the bacteria (ie Staph aureus), protecting it from phagocytosis. Of all 3 pathogenic staphylococcal species, only Staph aureus is coagulase positive.
What the purpose of mannitol salt?
The purpose is to select for salt-tolerant microbes. Most species of microbes can't grow in such a salty environment. The only genus that can culture on an MSA plate is Staphylococcus. The only species of Staphylococcus that can ferment Mannitol is Staph. Aureus. If the plate turns yellow, you know that Mannitol was fermented into an acid, which only Staph. Aureus can do. If there is a little growth (aka the culture is red) then it's still most likely a species of Staph such as Staph. epidermidis. If there is no growth, as in E. coli, then there will be no culture and no change in color.
Can Staphylococcus aureus cause toxic shock syndrome?
staph aureus is the causative bacterium of TSS.
What are the differences between staphylococcus aureus and enterococcus faecalis biochemical tests?
E.coli is a gram negative rod mostly isolated from urine while staph is a gram positive cocci. You can differentiate them by color. E. Coli is Pink which is negative while Staph is Purple with is positive.
What commonly infects wounds causes toxic shock syndrome and produces food poisoing?
Staphylococcus aureus (also known as staph aureus)
Does staph aureus causes worm-like movement in the body?
yes
Test used for the identification of Staphylococcus aureus?
staph. aureus test positive for catalase test and coagulase test consecutively
How does a unharmful staphylococcus turn into MRSA?
MRSA stands for methicilin-resistant staph aureus. MRSA is a type of staph, and a MRSA infection is a kind of staph infection.
What is the staph disease by the name of Neursa. My mother-in-law contacted it while in the hospital.?
MRSA - methicillin-resistant staph aureus
Should a baby with staph in the blood be hospitilized?
There are two sero-types of Staph that may be found in an infant: Staph epidermis (usually just a contaminant) and Staph aureus - Staph aureus is a highly dangerous microbe and would need IV antibiotics. So, the type of microbe in the blood and the medical condition of the baby would detemine if hospitalization is needed. RBB, MD
Why is it important to differentiate S aureas from S epidermis or S Saprophyticus?
In terms of microbiology, S. aureus and S. epi can be differentiated through a number of metabolic tests. The tests being Methyl Red, Vogues-Prauskauer, Mannitol fermentation (of which S. aureus would be + and S. epi - ) and Oxidase (S. aureus - and S. epi + ).
Which poisonous substance does staphyllococcus bacteria produce?
This is a aureus. This is a type of staph infection.
