Infection Pathology Flashcards
1
Q
Endotoxin
A
Feature of gram negative bacteria
0 LPS, Lipid A (anchors LPS)
Pathogenic in high levels
2
Q
Exotoxins
A
Proteases, hyaluronidases, coagulates, fibrinolysins
Toxins
Neurotoxins
Superantigens - stimulate T lymphocytes —> proliferation and cytokines release
Pseudo has significant exotoxin
3
Q
Gram positive wall structure
A
15-50nm thick - 50% peptidoglycan, acidic polymer 5-10% proteins and polysaccharides
4
Q
Gram negative wall
A
More complex,
Periplasmic space
Peptidoglycan layer 2nm thick
Complex polysaccharides (endotoxin)
