Characterization of an ecto-ATPase activity in Fonsecaea pedrosoi

Archives of Microbiology, 2006
In this work, we characterized an ecto-ATPase activity in intact mycelial forms of Fonsecaea pedrosoi, the primary causative agent of chromoblastomycosis. In the presence of 1 mM EDTA, fungal cells hydrolyzed adenosine-5'-triphosphate (ATP) at a rate of 84.6 +/- 11.3 nmol Pi h(-1) mg(-1) mycelial dry weight.

Fonsecaea pedrosoi produces ferricrocin and can utilize different host iron sources

Fungal Biology, 2023
The survival of living organisms depends on iron, one of the most abundant metals in the Earth's crust. Nevertheless, this micronutrient is poorly available in our aerobic atmosphere as well as inside the mammalian host. This problem is circumvented by the expression of high affinity iron uptake machineries, including the production of siderophores, in

Exoantigen test for Cladosporium bantianum, Fonsecaea pedrosoi, and Phialophora verrucosa

Journal of Clinical Microbiology, 1986
Exoantigens from 10-day-old cultures of 100 isolates of pathogenic and saprophytic dematiaceous fungi were analyzed by the exoantigen test. Antisera to Cladosporium bantianum ATCC 10958, Fonsecaea pedrosoi CDC AMO-B06, and Phialophora verrucosa CDC AMO-C12 were prepared in New Zealand rabbits immunized with soluble antigens from 1-month-old cultures ...

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.
