Paracoccidioides species present distinct fungal adherence to epithelial lung cells and promote different IL-8 secretion levels.

Fungi that belong to the genus Paracoccidioides are the etiologic agents of paracoccidioidomycosis, a human systemic mycosis, which occurs in Latin America. Epithelial cell is one of the first cells that interact with these fungi and responds by secreting inflammatory mediators such as cytokines. In the present study, we demonstrate that yeasts of different isolates of Paracoccidioides brasiliensis (Pb18 and Pb03) and Paracoccidioides lutzii (Pb01) distinctly promoted interleukin (IL)-8 secretion by the lung epithelial cell line A549.
