Term
Describe Staphylococcus Shape and if it is Catalase positive or negative
Definition
Circular cluster and is Catalase positive.
Term
Why is Catalase positive important
Definition
To prevent the nueutrophil and macrophage from destroying the bacteria. Neutrophil and macrophage use hydrogen peroxide and Catalase converts it into water and oxygen.
Term
What is the shape oif Strepalococcus and is it Catalase positive or negative?
Definition
Strep is circular and lines up in a straight row and is Catalase negative.
Term
List the three types of Strepolococcus
Definition
1.Group A Alpha
2. Group A Beta
3. Gamma
Term
List all the names for Group A Beta
Definition
1. Group A Beta
2. Strep pyogenes
3. Strep pharyngitis
4. Strep throat
Term
What does Strep Alpha, Group A do to red Blood cells?
Definition
It partially breaks up red blood cells giving them a green color under a microscope.
Term
What does Group A Beta do to red blood cells?
Definition
Breaks up the whole red blood cell to pieces. Color is a clear zone area of destroyed blood cells when seen in a microscope.
Term
What does Strep Gamma do to red blood cells?
Definition
Can not break red blood cells. No color or change is seen under a microscope. Also known as non hemolytic strep.
Term
What is Calase? Why is it important?
Definition
Breaks down Hydrogen Peroxide into Water and Oxygen. Important because Neutrophils and macrophage need hydrogen peroxide. Calase prevents it by changing it.
Term
What is another name for Strep Gamma?
