Path 8: Bacterial infections Flashcards
S. Auerus skin lesions
Boils, carbuncles, impetigo
S. Aureu binds to endothelial cells via
Surface receptors for fibrinogen, fibronectin, vitronectin
Superantigens from _____ cause food poisoning and toxic shock syndrome
Strep pyogenes
S. Aureus superantigen pathogeneisis
Binds to MHC to stimulte T-Cells which then leads to release of TNF and IL-1
Scarlet fever cause
S. Pyogenes
Glomerulonephritis bacteria cause
S. Pyogenes
Major cause of caries
S. Mutans
S. Pyogenes virulence factor
M protein
Bacteria that causes dyptheria
Corynbacterium Diptheriae
Diptheria toxin
A-B toxin that blocks host cell protein synthesis
Listeria caused by

Abortion, stillbirth, neonatal sepsis
how does listeria escape phagosomes
Listeriolysin O. Forms pore in phagosome and escapes
Anthrax in skin
Causes a vesicle that pops and has a black eschar
Inhalational anthrax
1-6 day fever and cough followed by rapid sepsis, bacteremia and possibly sepsis
Nocardia spp. found in
Soil
Bacterial meningitis from a dorm

Pseudomonas mostly affects
In an opportunisitc way. Burns, cystic fibrosis, AIDS, neutropenia
Pseudomonas virulence factor
Exotoxin A
Plague caused by

YOPS
YOPS is injected into host cells to stop phagocytosis
Chancroid caused by
