A case of eumycetoma of foot in an 8-year old male child was clinically diagnosed as chronic osteomyelitis and was microbiologically confirmed as eumycetoma. The case is being reported for its uncommon clinical presentation and etiological agent, Exophiala jeanselmei. The patient recovered completely after treatment with ketoconazole.

Eight cases of imported mycetomata in The Netherlands are reviewed. Seven of these were cultured; only one isolate, Actinomadura madurae, belonged to a species commonly known as an agent of mycetoma. The remaining strains either belonged to very rare species, such as Phialophora cyanescens, or could not be identified at all. The list of possible agents of mycetoma apparently needs to be expande...

Melanized wild-type and melanin-deficient (Mel-) strains of Wangiella dermatitidis (Kano) McGinnis were tested for in vitro susceptibility to amphotericin B, flucytosine, amorolfine, ketoconazole, fluconazole, terbinafine, and itraconazole by using an agar dilution technique. Although the MICs of itraconzole obtained with seven of the eight Mel- strains were lower than those obtained with the m...

Exophiala (Wangiella) dermatitidis is an emerging dematiaceous fungus associated with high mortality rates and is a rare cause of endocarditis. We describe the first case of E. dermatitidis endocarditis of a prosthetic aortic valve and aortic graft in an immune competent patient with no clear risk factors of hematological acquisition.

The present study reports the characterization of psychrophilic yeast and yeast-like diversity in cold habitats (superficial and deep sediments, ice cores and meltwaters) of the Calderone Glacier (Italy), which is the southernmost glacier in Europe. After incubation at 4 and 20 degrees C, sediments contained about 10(2)-10(3) CFU of yeasts g(-1). The number of viable yeast cells in ice and melt...

Exophilin A, a new antibacterial compound, was discovered in the culture of the marine microorganism Exophiala pisciphila NI10102, which was isolated from a marine sponge Mycale adhaerens. The absolute chemical structure of exophilin A was elucidated as a trimer of (3R,5R)-3,5-dihydroxydecanoic acid by spectroscopic methods and analyses of a degradative product. Exophilin A showed antimicrobial...

Phaeohyphomycosis is an infection caused by a filamentous fungus that contains pigment melanin in its cell wall. We report two cases caused by Exophiala sp. emphasizing the clinical variability of the disease, as well as diagnostic and therapeutic difficulties of this opportunistic infection in immunosuppressed patients (kidney transplant).

We have previously conducted a microflora analysis and examined the biofilm-forming activity of bacteria isolated from toilet bowl biofilms. In the present investigation, to reveal the strain involved in the formation of black dirt in toilet bowls, we performed a microflora analysis of the bacteria and fungi isolated from the black dirt of toilet bowls at ten homes. Among samples from different...
