Overview

Pathogenesis

  • Spores of paracoccidioides are transmitted via the respiratory route to the human host
  • Conidia and mycelial particles "reach the terminal brochioles and alveoli, where they are transformed into yeast cell"
  • "the infection can spread to other tissues via lymphatic and hematic" [1]
  • "The fungi developed mechanisms (such as adhesion to host cells), to avoid entrapment within mucus and their elimination by mucigen cilliary cells" [2]
  • "their effective adherence contributes to higher speed invasion of host cells, allowing for evasion of the immune system" [2]
