Superoxide dismutase Produced with catalase to detoxify superoxide and hydrogen peroxide that is produced
Facultative Growaerobically or anerobically in the presence or absence of O2
Microaerophilic Requires low O2 concentration and generally a high CO2 concentration
Obligate anaerobic Incapable of aerobic metabolism but are tolerant of O2
Capnophilic Thrive in high CO2 concentrations
Aerotolerant Do not require O2 as they metabolise anaerobically
Acceptable Specimens (anaerobes) protected from O2, taken from: blood, bile, bone marrow, CSF, lung aspirate, dental/abdominal/pelvic abscess, burn wound
PEA agar Supports all obligate anaerobes (gram positive and negative), used to suppress growth of gram negative facultative (like Proteus)
Bacteroides Fragilis resistant to penicillin and not inhibited by bile, most common anaerobe, BBE agar
Clostridium Perfringens cause of gas gangrene, double zone of hemolysis, lecithinase positive
Clostridium Botulinum Canned foods, lipase positive, causes Botulism
Clostridium Tetani neurotoxin, lockjaw, gram positive bacilli with spores like drumsticks or tennis rackets, indole positive, motile
Clostridium Difficile Pseudomembranous colitis, indole/glucose/fructose positive, motile
Mobiluncus cause of anaerobic vaginosis, nonmotile, catalase and indole negative, curved bacilli
