PATHOGENS

  • Main human pathogen:
    • Cryptococcus neoformans (predominant)
      • Four serotypes (A to D) described based upon the capsule components.
      • Three varieties described as causing human disease C. neoformans v. neoformans (most common), v. gattii, and v. grubii (recently established).
