Evaluation of a novel modified selective medium cefixime-tellurite-phosphate-xylose-rhamnose MacConkey agar for the isolation of Escherichia albertii from diarrheal stool specimens.

ABSTRACT: It is challenging to isolate Escherichia albertii from clinical specimens. Therefore, a medium that can selectively grow E. albertii and differentiate it from E. coli is earnestly desired. Here, we describe the evaluation of a recently developed selective differential medium, called cefixime-tellurite-phosphate-xylose-rhamnose-MacConkey (CT-PS-XR-MacConkey) medium, which enables the specific growth of E. albertii and differentiation of E. albertii (colorless) from E. coli (red) based on colony color and thus, facilitating the efficient isolation of E. albertii from diarrheal stool. When three E. albertii negative diarrheal stools were inoculated onto CT-PS-XR-MacConkey and xylose-rhamnose-melibiose (XRM) containing MacConkey agars, no colorless colonies were observed on both the media.
