Objective: The objective of this study was to isolate and identify the fungal agents obtained from clinical samples of suspected mycoses patients attending Yenepoya hospital.Methods: Various clinical samples obtained from patients were subjected to preliminary examination according to standard mycological protocols such as KOH mount, wet mount, Gram’s staining, and Indian ink examination. Causative organisms were identified by macroscopically and microscopically after growth on sabouraud’s dextrose agar (with or without cycloheximide and chloramphenicol) and confirmed by lactophenol cotton blue mount, slide culture technique, urease test, and growth on chrome agar accordingly.Results: Of 274 clinical samples, 125 were culture positive in which the fungal isolates obtained were dermatophytes (all 3 genera), Candida species (including Candida albicans), Fusarium species, Aspergillus fumigatus, and Cryptococcus neoformans. Male predominance was found among the patients being 6:3 male:female ratio.Conclusion: Among the superficial infection, Trichophyton mentagrophytes was found to be predominant isolates; however, in systemic infection, C. albicans was the predominant isolates.

BackgroundHistological and mycological changes during itraconazole use have not been totally established in chromoblastomycosis.ObjectivesTo evaluate tissue modifications in chromoblastomycosis carriers under itraconazole treatment.MethodsA histological retrospective study of 20 cases of chromoblastomycosis seen at the university hospital at the south of Brazil, during itraconazole 400 mg daily treatment. Patients were classified into two groups: plaque or tumor lesions, and underwent periodic evaluations every four months during three years. Hematoxylin-eosin stain was used to analyze epidermal modifications, inflammatory infiltrate and fibrosis, and Fontana-Masson stain for parasite evaluation.ResultsFontana-Masson stain was superior to hematoxylin-eosin stain in fungal count in the epidermis (mean difference=0.14; p<0.05). The most distinct mycosis tissue responses were registered in the dermis. Epidermal thinning, granulomatous infiltrate decrease or disappearance, fibrosis increase and quantitative/morphological changes occurred during treatment.Study limitationsPatients could not be located to have their current skin condition examined.ConclusionParasitic and tissue changes verified in this study can reflect the parasite-host dynamics under itraconazole action.

Despite F. pedrosoii being the most common agent of cutaneous blastomycosis, there are few reports of ocular infection by this agent in the literature. This article describes an unusual case of keratitis due to Fonsecaea pedrosoi, which developed after corneal trauma. The patient was a 35-year-old man who presented with a corneal ulcer in the right eye, after sustaining an injury caused by raw vegetable matter. Corneal scrapings were collected for smear and culture examinations. Dematiaceous hyphae were seen on wet mounts of the scrapings, and dark pigmented colonies grew on the culture media. Isolate was identified as Fonsacea pedrosoi.
