Dear Editor,

I read the recent publication on yeast identification in routine clinical microbiology laboratory and its clinical relevance with great interest. [1] The authors conclude that the use of chromogenic medium with morphology on CMA provides rapid and accurate identification of commonly isolated single or multispecies yeast. However, we have the following concern.

In the present study, the yeast isolates were identified on the basis of growth on Cornmeal Agar through slide culture. The slide culture technique in mycology is used to study the undisturbed morphological details of the mycelial fungi. The advantage of using slide culture for yeast identification is not understandable when similar results can be achieved on CMA on a  Petri dish More Details. The authors have included chromogenic media for confirmation of yeast identification. In the present study, the striking similar results on the chromogenic media and CMA can be an observer bias. In a recent publication by Baradkar et al, sensitivity and specificity for different Candida species have been reported to be variable. [2] Also, absent from this study was estimation of the sensitivity and specificity of yeast identification by various methods. For yeast identification, biochemical tests like sugar fermentation and assimilation are of immense importance and cannot be overlooked.
