Binding of laminin to Paracoccidioides brasiliensis induces a less severe pulmonary paracoccidioidomycosis caused by virulent and low-virulence isolates

Andre, D. C.; Lopes, J. D.; Franco, M. F.; Vaz, CAC; Calich, VLG (Elsevier B.V., 2004-05-01)

The pathogenic fungus Parracoccidioides brasiliensis is the causative agent of paraeoccidioidomycosis (PCM). This pulmonary mycosis, acquired by inhalation of airborne propagules, may disseminate to several internal organs ...
