Anaselect® Plates

Frequently, the clinical microbiologist encounters a situation where sensual evidence (odor) suggests that an anaerobe is present on a plate directly streaked with a specimen, yet a distinctive anaerobe colony can not be isolated. This happens when the anaerobe is present in very low numbers relative to the facultative microbes. This can result from rapid growth of facultative microbes in the transport medium while anaerobes are growing slowly or not growing at all. The anaerobe is being diluted to extinction by growth of the facultative microbes. The anaerobe may be present in the first quadrant on the plate, but buried in the mass of facultative growth.

The AnaSelect® plate provides a means to significantly reduce background growth of facultative microbes when directly plating a clinical specimen. This reduction enhances the number of anaerobe colonies relative to the number of facultative colonies on the plate, improving the isolation of the anaerobe.  Click here for more information

For even more selectivity, use the AnaSelect® plate after first enriching for the anaerobe in an AnaSelect® for Broth culture of the specimen.

The AnaSelect® plate uses the Brucella Blood Agar media formulation. See the learning center for more details
