Yeasts isolated from beef heifers with ringworm

Bovine dermatophytosis has a negative impact in cattle breeding and can cause zoonoses. The aim of this study was to report a ringworm outbreak in Brazil and to evaluate the presence of yeast in the lesions. After weaning, 88 hybrid beef heifers in feedlot were clinically investigated. Lesions sugge...
