32
Q

What are bacterial endotoxins?

A

LPS: structural componeent of outer cell wall in gram neg bacteria to activate immune response

33
Q

What are bacterial exotoxins?

A

Toxins released by bacteria to allow it to adapt and survive

35
Q

What are the 5 inflammatory responses to infection?

A
Suppurative
Mononuclear/granulomatous
Cytopathic/Cytoproliferative
Necrotizing
Chronic/Scarring
36
Q

What is suppurative inflammation?

A

Caused by pyogenic bacteria

Leads to increased permeability and neutrophil recruitment and infiltration

37
Q

What is mononuclear/granulomatous inflammation?

A

Diffuse mononuclear interstitial infiltrates

Lymphocytes and macrophages forming giant cells

38
Q

What is cytopathic/cytoproliferative inflammation?

A

Rxns of virus mediated damage to individual host cells in absences of host inflammatory response

39
Q

What is necrotizing inflammation

A

Rapid and severe tissue damage with cell death
