Cryptococcosis Causes and Risk Factors. The major causes of cryptococcosis are infection by C. neoformans and C. gattii. These two species have several types (serotypes) of different capsular polysaccharides that cause the majority of human cryptococcosis (A, D, and AD for C. neoformans; B and C for C. gattii).

Cryptococcus neoformans yeast cells 40 to 60 micron in diameter were seen in an India ink preparation made from a human brain abscess specimen. In culture at 25 degrees C, uniform 5-micron-diameter yeast cells were produced.
