Lecture 7 Flashcards
Coagulase+, yellow colony
o Protein A, many secreted enzymes & toxins
o Frequently drug resistant
o Food poisoning, osteomyelitis, toxic shock syndrome, nosocomial
infections, skin infections: abscesses (stye, boil, carbuncle) and impetigo
S. Aureus
No coagulase, white colony
o Capsule
o Frequently drug resistant
o Catheter & prosthetic implant infections
S. Epidermis
No coagulase, white colony, Urinary tract infections in young women (behind E.Coli)
S. SAP-RO-PHY-TI-CUS
Which has TRUE food poisoning? (vs an infection)
Staph!
What is the disease caused by Exfoliative toxin? What stage of infection is it?
Scalded Skin Syndrome…Systemic Toxic diesase
What disease is caused by Toxic Shock Syndrome Toxin (TSST-1)?
Toxic Shock Syndrome (REAL, not the fake strep crap)
Why can’t IgG bind to Staph AUREUS?
Staph is covering with Protein A
What staph AUREUS virulence factor will produces local fibrin deposition that can act to wall off the infection? OR coats themselves individually?
Coagulase
What causes TRUE food poisoning? FLIGHT FROM TOKYO to PARIS!!
ENTEROTOXIN-a superantigen, very heat resistant
What were the long lasting tampons an example of?
TOXIC SHOCK Syndrome (super antigen TSST-1)
Which is MORE virulent? Staph TSST-1 or Strep TSSLT?
Strep TSSLT actually!
What is a hospital, doctor aquired Staph infection?
No-So-Co-Mal infection (hospital) I-at-ro-genic (doctor aquired)
What staph invades via catheters/ needle inn?
Staph Epidermis
What happens when antibiotics knock out normal flora and S. Aureus takes over?
Staph caused EnteroColitis
What are Local skin infections, Deep/localized infections, acute endocarditis, and pneumonia all classified as?
Local Pyogenic Staph infections
