RESUMO
A preliminary comparative study, by 4 independent groups, of certain extracts of Candida albicans, showed variation in their antigenicity. Different agar gel double diffusion tests were used by each group; two groups used micro-methods and two used macro-methods. The number of positive precipitin reactions detected by these methods was shown to vary greatly.

The tetrazolium medium described is easily prepared and serves as a rapid, relatively accurate and simple means of differentiating Candida species, particularly C. albicans, from other yeasts. Culture on this medium does not replace other techniques used for yeast identification. No one test alone will suffice and final identification must rest on an overall pattern of characteristics. In the screening of 1,822 yeast isolates in this laboratory, culture on this medium has proved a valuable adjunct to other recognized techniques, and is now in regular use.

The lesions produced by six Candida species on the chorioallantoic membrane (CAM) of the developing chick are described and compared. It is suggested that CAM inoculation be used as a pathogenicity test for Candida species.

Metastatic candida endophthalmitis presented as a unilateral panuveitis in an apparently healthy drug addict. Diagnosis was confirmed by vitrectomy. The eye made an excellent response to treatment with the new antifungal drug, ketoconazole, and 5-fluorocytosine. Problems raised in the diagnosis and management of this infection are discussed.

Genital yeast infection was studied in 533 women seen in a department of venereology. Yeasts were recovered in culture from 138 patients (26% of the total). Candida albicans accounted for 112 (81%) of the isolates and Torulopsis glabrata for 22 (16%); other yeasts were uncommon. There was no evidence that the presence of yeasts was related to age. 32% of the women who were taking an oral contraceptive harboured yeasts, compared with 18% of those who were not.The symptoms and signs of the women with yeast infections were compared with those with vaginal trichomoniasis and those with no evidence of genital infection. It seems that a clinical diagnosis of vaginal mycosis cannot be made with accuracy and that positive identification of yeasts is necessary; for this, cultural methods are the most satisfactory.
