| cell-surface hydrophobicity and lipolysis as essential factors in human tinea nigra. | hydrophobic adhesion of cells of the black yeast hortaea werneckii (horta) nishimura & miyaji, causative agent of human tinea nigra, was established by microbial adhesion to hexadecane (math) and adhesion to polystyrene, and compared with adhesion of other species of black yeasts. additional ecophysiological tests were performed. hortaea werneckii cells proved to have a high degree of hydrophobicity (98.5% math). the species is unable to degrade keratin, but shows significant lipolytic activity. ... | 1995 | 8720202 |
| tinea nigra by hortaea werneckii, a report of 22 cases from mexico. | tinea nigra is a superficial mycosis caused by hortaea werneckii. it is an infrequent asymptomatic infection that affects human palms and soles, and is mostly observed in tropical countries. we evaluate retrospectively twenty-two confirmed cases of tinea nigra from a total of eleven yr (1997-2007) and discuss the epidemiology, clinical features and treatment of this disease. in twelve cases, adults were involved, in 10, children. in nineteen cases the disorder was located on palms of hands and i ... | 2008 | 19287529 |
