Mitochondria of cytoplasmic male sterile crop plants contain novel, chimeric open reading frames. In addition, a number of crops carry endogenous double-stranded ribonucleic acid (dsRNA). In this study, the novel proteins encoded by these genetic components were screened for the presence of
The exoantigen of Paracoccidioides brasiliensis standardized by Camargo et al. (AgR) was used to evaluate the in vivo and in vitro cell immune response of experimental animals and of patients with paracoccidioidomycosis (PBM). Fava Netto antigen (AgF) was tested in parallel as a control antigen. The
A cellular antigen from Paracoccidioides brasiliensis, obtained from the supernate of the disrupted yeast phase, was studied. It was prepared by a method similar to that for obtaining the spherulin from Coccidioides immitis. This antigen is composed of 55 mug/mg of polysaccharides, determined by the
A purified glycoprotein of 43,000 daltons from Paracoccidioides brasiliensis (gp43) was tested as paracoccidioidin in delayed-type hypersensitivity (DTH) tests in both experimental animals (guinea pig and mice) and patients with paracoccidioidomycosis (PCM). The gp43 paracoccidioidin was compared
