[A rapid method for the diagnosis of Trichophyton verrucosum (author's transl)]

200 dermatological specimens from cattle with clinical symptoms resembling ringworm have been examined using direct microscopy of lye-treated material and cultivation on glucose peptone agar with examination of the cultures for microcolonies of Trichophyton verrucosum after 2-4 days incubation (Fig. 1 and 2). The results (Table I) show good correlation between the two examination methods. In 77 specimens arthrospores were demonstrated on direct microscopy and microcolonies of T. verrucosum on cultivation, 9 specimens were positive on direct microscopy only, 13 specimens were positive on cultivation only, and 101 specimens were negative on both methods. Other dermatophytes than T. verrucosum were not demonstrated.
