| Popis: | Despite of great number of investigations in the area of tinea pedis, question is opened: to what extent dermatophyte fungi are spread among modern population and does their occurrence interrelated with host age? Investigated group included 99 volunteers from 14 to 73 years old. Skin scales were collected from heel area of foot, and signs of heel skin trouble were expressed in points. In contrast to usual laboratory microscope magnification x900 we worked at x1750, what allowed to estimate not only fungal, but bacterial forms too. Average abundances of microbial morphotypes were expressed in points. Heel skin trouble increased in the process of aging (Pirsons` coefficient r=0.954). Bacilli occurred in all persons independently from age, but their abundance increased with aging (0.821). On the contrary cocci were more common and abundant in young person`s feet (-0.620). Occurrence of dermatophytes increased with age (0.891), at that relatively high values took place in young persons (10.5% with mycelium and 73.7% with spores) and in group without any heel skin trouble symptoms (7.7% and 76.9%), what allow to refer these fungi to normal habitats of foot skin. |
