What are the characteristics of anaerobic infections?
Foul-smelling discharge
Gas in necrotic tissue
What are some predisposing conditions for anaerobic infections?
Pulmonary aspiration, bowel surgery, poor dental hygiene, abortion, human bites or animal bites, trauma, malignancy
Describe an ideal environment for anaerobic infection.
Deep or necrotic tissues where the oxygen is low and access to endogenous local bacteria is available
True or false
Reduction of redox potential may occur as result of: a)wound, b)impaired blood supply, c)tissue necrosis
True
True or false

True
What are some areas of the body susceptible to infections with anaerobic bacteria?
Skin and muscle infections
Peritonitis (appendicitis, intraabdominal abscesses)
CNS infections
OB/Gyn infections (puerperal or postabortion septis, tubo-ovarian abscesses), Dental infection, Lung infection
A patient has anaerobic infection in the lower abdomen area. Which organism would you suspect to be an infectious agent?
