Surface Characteristics
The cell wall contains a linear (1-->3)-linked mannan backbone singly substituted with nonreducing β(1-->2) xylose and β(1-->2) glucuronic acid side branches ; O-acetyl groups are present at C-6 of the mannosyl residues.
Pathogenic Activity
Infection with C. neoformans is termed cryptococcosis. Most infections with C. neoformans consist of a lung infection. However, fungal meningitis, especially as a secondary infection for AIDS patients, is often caused by C. neoformans making it a particularly dangerous fungus. Infections with this fungus are rare in those with fully functioning immune systems. For this reason, C. neoformans is sometimes referred to as an opportunistic fungus.
