Introduction to Clinical Mycology

Blastoconidia and Pseudohyphae

January 2012

An example of what we talked about a minute ago. The PH shows you pseudohyphae. You see those elongated yeast cells that have the narrowed ends. They look like links of sausages attached together and on the right hand side you see a blastoconidia or a yeast cell, big cell at the bottom with a bud at the top right at the tip of the arrow, that is a budding yeast cell, the blastoconidium. So this is what you might see a combination of those yeast cells and pseudohyphae. Any time you see a combination of a budding yeast cells, hyphae, or pseudohyphae, you know you are dealing with something that belongs to genus Candida because that is the characteristic of that particular genus.
