CHAPTER 42 Pathogenesis of Fungal Infections
... A. Innate Immunity 1. Normal persons have a high level of innate immunity to most fungal infections 2. Important receptors include a lectin-like structure on phagocytes and Toll-like receptors 3. Most fungi are readily killed by phagocytes 4. Tissue phases of dimorphic fungi resist phagocytic killin ...
