Abstract
Summary. The use of corneocytes in suspension as a medium for the study of the effect of antifun‐gal drugs on Trichophyton mentagrophytes arthroconidia was investigated. In the presence of clotrimazole or griseofulvin, arthroconidia germination in a suspension of corneocytes and in Sabouraud glucose liquid medium was significantly reduced compared with germination in drug‐free media. Where antifungals were added to arthroconidia after an activation period during which germination occurred, any further germination was inhibited. The data showed that the growth of T. mentagrophytes in the presence of corneocytes offered a simple, rapid, inexpensive and relevant model for the assessment of antifun‐gal activity of compounds for the treatment of dermatophytosis. Zusammenfassung. Es wurde die Wirkung von Antimyzetika auf Arthrokonidien von Trichophyton mentagrophytes in einer Korneozyten‐Suspension untersucht. In Gegenwart von Clotrimazol oder Griseofulvin war die Auskeimung der Arthrokonidien in der Korneozyten‐Suspension und in Sabouraud‐Glucose‐Bouillon signifikant vermindert, verglichen mit der Auskeimung in wirkstoffreiem Medium. Wurden die Antimyzetika den Arthrokonidien erst nach einer Aktivierungsperiode zugesetzt, während der sie auskeimten, war jedes weitere Wachstum gehemmt. Die Ergebnisse belegen, daß das Wachstum von T. mentagrophytes in Gegenwart von Korneozyten ein einfaches, schnelles, preiswertes und aussagefähiges Modell für die Wirksamkeitsprüfung von Antimyzetika in der Dermatophytosen‐Behandlung darstellt.This publication has 12 references indexed in Scilit:
