Use of rapid auxanographic procedures for recognition of an atypical Candida.

An atypical Candida which can cause diagnostic problems in clinical laboratories has recently been characterized. Assimilation patterns of 29 clinical isolates of an atypical Candida were obtained by the API 30C (Analytab Products, Plainview, N.Y.)., Uni-Yeast-Tek (Flow Laboratories, Inc., Rockville, Md.), and dye pour-plate auxanographic methods. The low frequency of assimilation of cellobiose, sucrose, and melezitose noted in all of these procedures permitted the early recognition of the atypical character of the isolates.
