Question

Pseudohyphae production on cornmeal agar is characteristic of all of the following yeasts

            except:

            a.         C. krusei

            b.         C. pseudotropicalis

            c.         C. albicans

            d.         T. (Candida) glabrata

34.       A yeast recovered from a vaginal specimen gave the following results:

            Germ tube = +                                    Blastospores = +

            Pseudohypae = +                    Arthrospores = 0

            Chlamydospores = +             

            The most appropriate set of follow-up tests is:

            a.         Carbohydrate assimilation and urease

            b.         Urease and pigmentation on niger seed agar

            c.         Nitrate reductase and carbohydrate fermentation

            d.         No further testing is needed for identification.
