Abstract
Fungi are eukaryotic, unicellular or multicellular organisms that are larger and genomically more complex than bacteria. The fungal cell wall is complex and has polysaccharides, proteins, sugars, and glycoproteins. Plasma membranes of fungi contain ergosterol, which is the primary target for antifungal drugs such as amphotericin B. Although more than 1.3 million fungal species exist in the environment, only about 150 are pathogenic to humans.1 The virulence factors of fungi resemble those of bacteria, such as possession of a capsule, adhesion molecules, toxins, free radicals, and so forth. Thus, fungi can elicit acute exudative, necrotizing, and granulomatous reactions in tissues. Although some generalizations are possible, the diverse structural and antigenic properties of individual fungi produce unique patterns of infection in individual hosts.2,5
