Reference broth microdilution protocols for the antifungal susceptibility testing (AST) of yeasts are available, but routine AST relies more on simpler alternatives. In this work, the Etest and a novel flow cytometry (FC) method were compared to the Clinical Laboratory Standards Institute (CLSI) protocol M27-A3. Caspofungin and anidulafungin were tested(More)
BACKGROUND Stenotrophomonas maltophilia (SM) has been considered a nosocomial pathogen. Nevertheless, community acquired infection may occur more frequently than usually recognized. CASE We describe distal necrosis of the fingers by SM in a farmer, contracted in the community and successfully treated with a combination of cotrimoxazole and ciprofloxacin.(More)
Phaeohyphomycosis is a rare, slowly progressive infection caused by a heterogeneous group of imperfect black or dematiaceous fungi that are found in plants and soil, and contain a cytoplasmic melanin-like pigment, which appears to have aetiological significance by decreasing the susceptibility of these organisms to antifungal agents. A commonly recognised(More)
We evaluated the incidence of dermatophytes isolated at our hospital in the years of 1997 to 2000 and correlated it with anatomical site and age. Trichophyton rubrum was the predominant species in all anatomical sites, excluding scalp, followed by Microsporum canis, the leading agent of tinea capitis. All dermatophytosis, except tinea capitis by M. canis(More)
A 67-year-old man was treated with cladribine for hairy cell leukaemia. A few weeks later, he presented with persistent headaches, intermittent hypoesthesia of the right upper limb and language impairment. Brain CT scan showed 3 contrast-enhancing lesions. MRI revealed infracentimetric nodular lesions with restricted diffusion. One of the lesions was(More)
We report an atypical case of Rhodotorula mucilaginosa fungemia coexisting with pleural tuberculosis, in an immunocompetent host. The patient was an inhaled drug abuser and worked in a fruit market. The diagnosis of Rhodotorula mucilaginosa infection was established by the isolation of the yeast in two blood cultures followed by a good response to(More)
Cryptococcal infection has been increasing among immunosuppressed population. We report three cases of Cryptococcus neoformans infection in immunosuppressed patients - two renal transplanted and one with lupus nephritis. Early infection (<3months) was diagnosed in two - an allograft Cryptococcus infection and a central nervous system involvement. The third,(More)
