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.

Paracoccidioides brasiliensis – the man-hater
Mycologist, 2002Some fungi are found only in specific geographical regions. The human pathogen Paracoccidioides brasiliensis has only rarely been isolated in nature and incidences of infections are restricted to Central and Southern America. Most commonly infected individuals are not urban dwellers, but rather farmers and people living in mountainous areas.

Blastomyces (Paracoccidioides) brasiliensis in Africa
Nature, 1964SINCE the discovery of “South American Blastomycosis” by Adolfo Lutz in 1908, it has been generally accepted that the disease is confined to South America. The few cases reported outside this region are of patients who lived for years in South American countries and probably contracted the “Lutz disease” there1–8.

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

Digestion of killed Paracoccidioides brasiliensis by neutrophils
Mycopathologia, 1989We previously described an in vitro assay showing that neutrophils (PMNs) from patients with paracoccidioidomycosis (PARA) have a specific digestive deficiency against suspensions of live Paracoccidioides brasiliensis. We now report that this defect is equally detectable against autoclaved, but not Amphotericin B-killed P. brasiliensis.

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 ...

The response of Paracoccidioides spp. to nitrosative stress
Microbes and Infection, 2015Paracoccidioidomycosis (PCM) is an endemic disease in Latin America caused by species belonging to the genus Paracoccidioides. During infection, immune cells present a variety of defense mechanisms against pathogens. One of these defensive strategies is the production and release of nitric oxide (NO) and S-nitroso thiols (e.g., S-nitrosoglutathione ...

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

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 ...
