MALASSEZIA SPECIES2 Microscopic appearance (Microscopic cell morphology) of Malassezia species. M. furfurcells are spherical and consist of a different bottleneck at one end. It is typically found in single cell individuals although unlike other species of Malassezia it forms filaments when it becomes its pathogenic form.M. dermatisappear as oval or round budding yeast-like cells of 3 to 8 μm in diameter staining dark blue. The cells shape is ovoid, ellipsoidal or globose and its budding is monopolar on a moderately broad base (Garrison & Arnold, 2018). On the other hand, the shape of the cells ofM. restrictais ovoid or globose, and budding is monopolar on a relatively narrow base. The cells ofM. japonicaare short ovoid to cylindrical of about 33 μm with budding which is monopolar on a broad base. Colony morphology on Sabouraud’s agar. When malassezia species colonies are sowed in Sabouraud’s agar,M. dermatisdue to its lipophilic attributes form globular shaped yeast with its cells round shaped which appear elongated maintaining a narrow base.M. furfuris lipophilic although able to produce small colonies without supplementation of lipids in which its colonies appear to be cream to yellow- brown and they appear smooth and soft and friable, often becoming brittle and wrinkled as they age (Celis, Wösten & de Cock, 2017). The colonies ofM. restrictaappear small, flat or raised colonies 1 to 2 mm in diameter on average, pale yellowish-brown, dull, smooth with a lobate margins andM. japonicaform flat, slightly wrinkled single colonies around 2 to 3 mm in diameter, pale yellowish cream, dull and butyrous with a straight or folded margin. Normal habitat. Malassezia furfurneeds an environment high in fats and oils to flourish since it is lipophilic yeast hence lives on the epithelial cells of humans where it consumes the natural oils
