The two hundred and five strains of Candida isolated from the saliva of human mouth have been studied for the mycological characteristics and their presumed susceptibility against the organism Sb-2w which was recently found to inhibit some strains of Candida. The results of the stndy were summarized as follows. 1) Since no consistent pattern was followed by strains of Candida in the test of any one of their morphological and physiological characters, a general consideration of all the characteristics involved was frequently relied upon as final criterion for differentiation and classification of these organisms. It may, however, be emphasized that of these relatively unreliable characteristics in the bacterial physiology and morphology, carbohydrate fermentation has proved fairly consistent in the main strains of organisms isolated from the mouth, and would deserve attention as one of the important means for identification of the organisms concerned. 2) So far, Candida albicans and Candida tropicalis have been claimed to be differentiated purely on the basis of sucrose fermentation according to the classification table of Martin et al. However, of the total strains of Candida albicans isolated from the mouth there was confirmed occurrence of fairly large number of organisms (25%) which demonstrated quite the same patterns with Candida tropicalis in the behaviour of fermenting glucose, maltose, sucrose and lactose, especially in producing acid and gas from sucrose. 3) Of the 116 strains of Candida albicans forming the chlamydospore, 33 strains (20%) had a difficulty in developing it. 4) The inhibiting action of the organism Sb-2w (Kobayashi) against the strains of Candida albicans was developed invariably and especially in the early stage of their growth. This phenomenon may be valuable in the precise and early identification of Candida albicans when used together with the classification table of Martin et al.. 5) Of 205 isolates of Candida there were found 167 strains of C. albicans, 12 strains of C. tropicalis, 12 strains of C. krusei, 7 strains of C. parakrusei, 1 strain of C. pseudotropicalis, 1 strain of C. Guilliermondii, 2 strains of C. stellatoidea and 3 strains of organism unidentified.
