Summary: | Summary. The epidemiology of human dermatophytes was studied in northern Finland in 1982–90. The samples were analysed at the Department of Medical Microbiology, University of Oulu. The total number of samples was 17 822, of which 3185 (18%) were positive. The annual number of samples and positive cultures remained relatively constant. Trichophyton rubrum was the most common species being isolated from 2101 samples (66% of all positive cultures), while Trichophyton mentagrophytes was isolated from 815 samples (26%) and Epidermophyton floccosum from 193 samples (6%). T. verrucosum caused an epidemic among cattle keepers in 1987–90, causing 47 infections. Microsporum canis, T. terrestre and T. violaceum were rare. The same species affected both children and adults. There was a tendency towards a decrease in tinea in the groin and a slight increase in tinea pedis. T. rubrum and T. mentagrophytes occurred most frequently in patients aged 41–45 years and as foot infections. E. floccosum usually affected the toe web and the groin in patients aged 21–25 years, more often infecting men. Fifty‐four per cent of all positive samples came from men and 46% from women. Zusammenfassung. In der Arbeit wurde die Epidemiologie humaner Dermatophyten in Nordfinnland im Zeitraum 1982–1990 untersucht. Die Proben wurden am Institut für medizinischen Mikrobiologie der Universität Oulu analysiert. Die Gesamtzahl der Proben betrug 17 822, von denen sich 3185 (18%) als positiv erwiesen. Die jährliche Anzahl der Proben und der dabei erhaltenen positiven Kulturen war relativ konstant. Trichophyton rubrum war mit 2101 Isolaten von allen Proben (66% aller positiven Kulturen) am häufigsten. Trichophyton mentagrophytes wurde aus 815 Proben isoliert (26%) und Epidermophyton floccosum aus 193 Proben (6%). T. verrucosum verursachte in den Jahren 1987–90 bei Tierhaltern eine Epidemie und löste 47 Infektionen aus. Microsporum canis, T. terrestre und T. violaceum traten selten auf. Die selbe Spezies befiel sowohl Kinder als auch Erwachsene; es war ... |
