Paracoccidioides brasiliensis is found only in Latin America. It is endemic in Mexico, Central America, and South America. Most cases (80%) have been reported from Brazil, followed by Venezuela, Colombia, Ecuador, and Argentina. Most cases occur in tropical and subtropical forests, where temperatures are mild and humidity is high ...

Morphogenesis in Paracoccidioides brasiliensis
2011Paracoccidioidomycosis (PCM) is a deep systemic mycosis originally described in 1908 caused by the ascomycete Paracoccidioides brasiliensis, a thermodimorphic fungal pathogen. The disease is autochthonous to Latin America and areas of higher incidence occur in countries such as Brazil, Argentina, Colombia, and Venezuela.

Paracoccidioidal infection in the wife of a patient with paracoccidioidomycosis
Medical Mycology, 1979Three agar immunoprecipitin techniques (double immunodiffusion, immunoelectrophoresis and immunoelectroosmophoresis-immunodiffusion) made with paracoccidioidin and serum of a paracoccidioidomycosis patient's wife, permitted us to observe a specific band in 6 successive samples of blood taken from the wife over a period of 21 months. The case represents

Isoenzyme profile ofParacoccidioides brasiliensis
Medical Mycology, 1995Isoenzyme profiles of 10 strains of Paracoccidioides brasiliensis from different origins (nine strains from patients with different clinical forms of paracoccidioidomycosis and one from the faeces of a penguin) were determined by polyacrylamide gel electrophoresis using 37 different enzymes.

Cytosolic Neutral Proteinases of Paracoccidioides brasiliensis
Current Microbiology, 1998Cytosolic proteinases were assayed in both morphological phases of Paracoccidioides brasiliensis. Preparations from the mycelial phase were more active in vitro than those from the yeast cells. Optimal proteinase activities for both phases occurred at pH's between 6.0 and 9.0, and at 45 degrees C.

Paracoccidioides spp. and Paracoccidioidomycosis
2017Paracoccidioidomycosis, the most prevalent deep mycosis of Latin America, is caused by Paracoccidioides spp., pleomorphic fungi which are present as multibudding yeast cells in infected tissues. Due to their importance to the region, these fungi and their related disease have been the subjects of intense research for over 50 years.

Effect of drying onParacoccidioides brasiliensis
Medical Mycology, 1971The susceptibility to drying of Paracoccidioides brasiliensis growing on sterilized soils, was investigated using 2 strains with different sporulating capacities. Decreased fungal viability was noted during the 31 day experimental periods. The sporulating strain surpassed its initial viability at the fifth day when 75 days old culture was used, but not

Characteristics of Environmental Paracoccidioides brasiliensis Isolates
Mycopathologia, 2009The ecological niche or exact habitat of the fungus Paracoccidioides brasiliensis is not known, and few isolates have been obtained from the environment. In this study, ten isolates were analyzed with respect to antigenic composition, serology, pathogenicity, and molecular aspects.

Ecology of Paracoccidioides brasiliensis
2018The relationship between Paracoccidioides brasiliensis and its environment is still a matter of debate as the fungus microniche is yet to be discovered. P. brasiliensis has deceived many of the researchers interested in finding its permanent residency. Many skin-testing surveys have been conducted with the aim of delimiting the areas of endemicity and ...
