A case of feline phaeohyphomycosis due to Fonsecaea pedrosoi

Veterinary Dermatology, 2001
AbstractThe first report of a case of feline phaeohyphomycosis due to Fonsecaea pedrosoi is presented. Fonsecaea pedrosoi is an aetiologic agent of both human phaeohyphomycosis and chromoblastomycosis. In our cat, the lesion was confined to the skin and appeared as a firm swelling on the bridge of the nose.

Heat-shock response in Fonsecaea pedrosoi, a pathogenic fungus

Canadian Journal of Microbiology, 1992
Using two-dimensional electrophoresis we have investigated the heat-shock response in a pathogenic fungus, Fonsecaea pedrosoi. Fungal cultures were transferred from 37 to 45 °C for either 30 or 90 min and then returned back to the initial temperature.

Chromoblastomycosis due to Fonsecaea pedrosoi and F. monophora in Cuba

Mycopathologia, 2013
We report two cases of chromoblastomycosis due to Fonsecaea pedrosoi and F. monophora in otherwise healthy Cuban males. Direct microscopic examination of biopsies revealed muriform cells, the hallmark of chromoblastomycosis. The suspected agents were recovered in culture, identified on the basis of morphological criteria and confirmed by sequencing of ...

Defense mechanisms of mice against Fonsecaea pedrosoi infection

Mycopathologia, 1981
Defense mechanisms of a host against Fonsecaea pedrosoi infection were studied histopathologically using athymic nude (nu/nu) mice of BALB/c background and their heterozygous (nu/+) littermates. Thirty male nu/nu and 30 nu/+ mice, weighing 16–19 g, were employed in this experiment. The nu/nu or nu/+ mice were divided into 3 groups consisting of 10 each.

Ultrastructural characterization of melanosomes of the human pathogenic fungus Fonsecaea pedrosoi

Journal of Structural Biology, 2008
Melanin is a complex polymer widely distributed in nature and has been described as an important virulence factor in pathogenic fungi. In the majority of fungi, the mechanism of melanin formation remains unclear. In Fonsecaea pedrosoi, the major etiologic agent of chromoblastomycosis, melanin is stored in intracellular vesicles, named melanosomes. This

ITRACONAZOLE IN THE TREAMENT OF CHROMOBLASTOMYCOSIS DUE TO FONSECAEA PEDROSOI

International Journal of Dermatology, 1992
AbstractThe efficacy and tolerability of itraconazole in chromoblastomycosis due to Fonsecaea pedrosoi were evaluated in a non‐comparative open clinical trial in 19 Brazilian patients with histopathologically and mycologically proven active chromoblastomycosis. Patients were classified in terms of severity and received itraconazole at the dosage of 200

Cell-mediated immune responses in mice infected with fonsecaea pedrosoi

Mycopathologia, 1979
Time course of cellular and humoral immune responses in mice infected with Fonsecaea pedrosoi was investigated by using an antigen prepared from culture filtrate of this fungus. Mice were infected by intravenous injection with yeast-like cells of the fungus.

Primary mycotic abscess of the brain caused by Fonsecaea pedrosoi

Journal of Neurosurgery, 1995
✓ A case of cerebral abscess caused by Fonsecaea pedrosoi is reported in a nonimmunocompromised, 15-year-old boy. In the absence of a primary cutaneous lesion, this fungus was considered to be a primary neuropathogen. The fungus was cultured and characterized from the abscess material obtained at surgery.

Putative role of an ABC transporter in Fonsecaea pedrosoi multidrug resistance

International Journal of Antimicrobial Agents, 2012
Fonsecaea pedrosoi, a dematiaceous fungus, is the main agent responsible for chromoblastomycosis, a chronic and progressive mycosis of the skin and subcutaneous tissues. This disease can cause different types of lesions depending on the immune status of the host.

Skin test-active substance prepared from culture filtrate of Fonsecaea pedrosoi

Mycopathologia, 1979
Ethanol-precipitated substance (EP) was prepared from culture filtrate of Fonsecaea pedrosoi. EP was separated into two components by passing through a Sephadex G-50 column; the faster passing component was referred to as EP-1, the slower as EP-2. EP-1 and EP-2 were evaluated as an antigen for detecting cutaneous delayed hypersensitivity in patients ...
