The two important coagulase negative Staphylococcus are.
What is S. epidermis and S. saprophytics?
This bacteria is a common veterinary pathogen.
S. intermedius
Staphylococcus is mostly found here.
Nose
1-4 hours
This bacteria is gram positive cocci, catalase positive, coagulase positive
What is Stapylococcus aureus?
This bacteria is a contamination except in urine.
What is S. saprophyticus?
This test differentiates healthcare acquired from community acquired MRSA.
D-test (clindamycin and erythromycin)
This organism is catalase positive, coagulase negative, and novobiocin susceptible.
What is S. epidermis?
This virulence factor helps inhibit complement fixation.
What is Protein A?
This bacteria is catalase positive, and modified oxidase positive.
What is Micrococcus?
This virulence factor alters binding of penicillin type molecules.
What is penicillin binding protein 2?
This bacteria is gram positive cocci, beta hemolytic, catalase positive, coagulase negative
Staphylococcus haemolyticus
S. aureus causes the following infections.
Pneumonia, osteomylitis, toxic shock syndrome
The color Mannitol Salt Agar (MSA) is when S. aureus is plated on it.
What is yellow?
The slide coagulase test tests for this.
What is bound coagulase?
MRSA has this identifying gene.
The reason rabbit plasma is used in a coagulase test is for this principle.
What is convert fibrinogen to fibrin?
(Serum does not have fibrinogen as it is consumed in clotting)
Staphylococcus has this type of oxygen requirement.
Facultative anaerobes
When attending a picnic, the part of S. aureus that causes food poisoning is.
Enterotoxins
This virulence factor is toxic to neutrophils and macrophages.
What is Panton-Valentine Leukocidin?
This virulence factor is what causes scalded skin syndrome.
What is exfoliative toxins A & B?
The tube test yielded a false negative result when performing a free coagulase test, this caused it.
3% hydrogen peroxide is used in the catalase test to determine this.
What is Staphylococcus and Streptococcus
This organism is catalase positive, coagulase negative, and has a natural novobiocin resistant.
What is S. saprophytics?
Toxic shock syndrome is caused by this toxin
What is toxic-shock syndrome toxin 1 (TSST-1)?
