Wilkins-Chalgren Agar is used for the cultivation of anaerobic microorganisms in a laboratory setting. Wilkins-Chalgren Agar is not intended for use in the diagnosis of disease or other conditions in humans.

This medium was selected because it does not require the addition of blood to support satisfactory growth of most anaerobes. The survival of anaerobic bacteria is dependent on their sensitivity to oxygen, nutritional requirements, appropriate collection, culture medium, and incubation time and temperature.
