CohortThree groups were enrolled in this study: (1) 7 healthy individuals (29–53 years old), selected from the records of Hospital das Clı ´nicas da Universidade de Sa ˜o Paulo, who have had PCM in the past, had been treated for at least 2 years until considered cured, and remained healthy for at least the last 5 years after the completion of treatment (healthy cured [HC] group). They presented no sequels, had serological data indicating none reactivation of PCM, and had no sign or symptoms of any other debilitating disease at the moment of the study. (2) 5 healthy individuals who never had PCM or any other debilitating disease in the past (20–44 years old) and were non-reactors to the skin test with paracoccidioidin (healthy non-infected [HNI] group). (3) 5 paracoccidioidin-reactive individuals ( [10 mm indu- ration after 48 h, age range: 20–42 years), recruited from an endemic area located at the southwest of Brazil (Prata ˆnea, Sa ˜o Paulo state, Brazil) (healthy infected [HI] group).

Disease Introduction MechanismParacoccidioidomycosis (PCM) is the most prevalent systemic mycosis in Latin America and still the leading cause of death among the mycoses. Its causative agent, Paracoccidioides brasiliensis, is a thermo-dimorphic fungus that grows as a yeast-like structure in the host tissue and as mycelium in the environment. The infection is acquired by the inhalation of conidia produced by mycelia present in the soil under certain conditions. These conidia reach the lungs where they differentiate into the yeast form establishing the infectious process.
