Exophiala jeanselmei is clinically redefined as a rare agent of subcutaneous lesions of traumatic origin, eventually causing eumycetoma. Mycetoma is a localized, chronic, suppurative subcutaneous infection of tissue and contiguous bone after a traumatic inoculation of the causative organism. In advanced stages of the infection, one finds tumefaction,(More)
Candida species are considered the primary causative agents of denture stomatitis, but their role in colonization and disease in denture wearers remains undefined. In this study, we investigated risk factors associated with progression to Candida-related denture stomatitis in patients using complete dentures, and we genetically identified Candida isolates(More)
Black yeast-like fungi are rarely reported from superficial infections. We noticed a consistent prevalence of these organisms as single isolations from mycological routine specimens. To investigate the prevalence of black yeast-like fungi in skin, hair and nail specimens and to discuss the probability of these species to be involved in disease. Slow-growing(More)
BACKGROUND Chronic granulomatous disease (CGD) is a rare disorder of phagocytes in which absence of superoxide and hydrogen peroxide production in phagocytes predisposes patients to bacterial and fungal infections. The most common fungal infections in these patients are caused by Aspergillus species. CASE PRESENTATION Here, we describe Aspergillus(More)
BACKGROUND Pityriasis versicolor is a superficial infection of the stratum corneum which caused by a group of yeasts formerly named pityrosporium. The taxonomy of these lipophilic yeasts has recently been modified and includes seven species referred as Malassezia. The aim of this study is to compare the distribution of Malassezia species isolated from(More)
Malassezia species are a part of the skin microflora of neonates. Under certain circumstances, they can cause diseases ranging from simple pustulosis to lifethreatening fungemia in newborn infants. Little information is available about the epidemiology of Malassezia species in neonates. In the present study, we successfully isolated Malassezia yeasts from(More)
BACKGROUND Psoriasis is a non-contagious disorder that affects the skin as red scaly patches. Although the role of Malassezia species in the pathogenesis of psoriasis is still not fully understood, it is thought that these lipophilic yeasts might be a trigger factor in the exacerbation of psoriatic lesions. METHODS Using culture in a specific medium(More)
Griseofulvin - a mold metabolite produced by Penicillium griseofulvum - is an antifungal drug whose interaction with tubulin is poorly understood. In this study we cloned the beta-tubulin gene in Trichophyton rubrum, which encodes a polypeptide with 447 amino acids (accession number AAV33733). Nucleotide sequence comparison in data banks for both the(More)
Background: Chronic granulomatous disease (CGD) is a rare disorder of phagocytes in which absence of superoxide and hydrogen peroxide production in phagocytes predisposes patients to bacterial and fungal infections. The most common fungal infections in these patients are caused by Aspergillus species.
