Candida albicans (Enlarged view)​

Slide 1. Candida albicans​
This specimen from a cutaneous pustule contains yeast, which stain gram positive and are much larger than bacteria. Pseudohyphae and budding, ​
often present in Candida infections, are absent.​

Slide 2. Candida albicans​
​This KOH preparation of a pustule on a hand demonstrates yeasts, some of which are budding. Gram stain is often used instead of KOH preparations ​
to diagnose Candida infections.​

Malassezia furfur (Enlarged view)​
Slide 3. Malassezia furfur​
​The yeast Malassezia furfur (previously known as Pityrosporum orbicularae and as P. ovale) normally is found on the skin of adults. When it causes tinea (pityriasis) versicolor, a superficial cutaneous infection, it appears as yeasts and hyphae that look like "spaghetti and meatballs" as seen ​
in this KOH preparation of skin scrapings.​

Slide 4. Malassezia furfur​
​The addition of Parkers blue-black ink to a KOH preparation of M. furfur often increases the visibility of the organisms.​
