Most fungal infections of the cornea are secondary infections, caused by opportunis­ tic fungi that have invaded a diseased cornea or one that has been treated with corticosteroids or broad-spectrum antibiotics. Two ex­ ceptions are corneal infections due to Can­ dida albicans or Aspergillus species; these may infect an apparently normal cornea af­ ter minimal trauma. Superficial mycotic infect...

Persistent dermatomycosis (ringworm) caused by Trichophyton verrucosum affected 20 dairy calves aged between 3 months and 1 year and housed together. The infection also spread to 2 animal attendants working among the calves. The major clinical lesions observed on the affected calves were extensive alopecia and/or circumscribed thick hairless skin patches affecting the head, neck, flanks and lim...

Musca domestica L. were collected from cattle diagnosed with bovine ringworm to evaluate the potential of the house fly to disseminate Trichophyton verrucosum E. Bodin, a fungal dermatophyte that is the causative agent for ringworm in cattle. Fungal isolates were cultured from 45 individual flies on supplemented Sabouraud dextrose agar, and isolates were identified using morphological and micro...

The purpose of this report is to compare and contrast the salient features of urban and rural ringworm as seen in a study area of northeastern Michigan, and to discuss in detail evidence for the animal origin of human ringworm infections. The patients included were observed by one of the authors (E. A. H.) during a five-year period (1949—1954) in his dermatological practice, and specimen materi...
