Abstract
An inexpensive but practical and simple method is described for providing an environment suitable for the maintenance and survival of clinically significant anaerobic bacteria, consistent with the needs of a large-volume laboratory. This modification of the GasPak procedure is based on two concepts. One involved the storage of "freshly prepared" plating medium under a constant stream of carbon dioxide. The other concept was to use an anaerobe jar, continuously flushed with oxygen-free carbon dioxide, as a "holding receptacle" for the inoculated media Experience with this modification has shown that the number of isolations of anaerobic bacteria from clinical material can be increased significantly.
