Anaerobic Bacteriology

Anaerobe Culture Triage (cont.)

June 2012

We use a system called partial identification in which we report morphologies present by gram stain and aerotolerant when there are four or more total morphologies or three or more anaerobic morphologies.  And finally, we simply report the presence of mixed flora when there are five or more anaerobic morphologies present.
