Over a 1 year period 3296 specimens submitted for fungal culture were plated onto routine mycological media (RM) and CHROMagar Candida (CaC) to evaluate the capability of CaC to improve on RM. With RM, cultures producing single yeast isolates were identified from 802 specimens. CaC produced similar results, with 76% agreement. Of 761 specimens that yielded a single Candida species by RM, 615 (81%) produced one or more yeast isolates using CaC. Of concern, 132 negative CaC cultures corresponded to specimens that yielded C. albicans alone on RM. When yeasts were recovered, CaC correctly identified 98% of C. albicans, 93% of Candida tropicalis, 96% of Candida glabrata and 100% of Candida krusei based on typical colours. CaC did potentially improve on RM by detecting yeasts in 91 specimens that yielded none by routine methods. CaC was noted to recover more yeast isolates than RM when mixed cultures were detected. Overall, the role of CaC in improving RM appears limited.
