--- With the objective to determine the frequency of presentation of the White Line Disease (WLD), the hooves of 16 Peruvian Paso horses of a private equine center and of 23 Hannoverian - Thoroughbred crossbred horses pertaining to Central Veterinary Hospital of the Army (Lima – Peru), were examined. The diagnostic method used was the clinical observation of the area of union wall – sole during the hoof trimming. All the evaluated equines (100%) had WLD at least in one hoof. Only were reported lesions of light grade and moderate grade in 50 (32%) and in 69 (44.2%) examined hooves, respectively. The clinical cases of the severe grade previously reported by Kuwano et al. (1998) and Oke (2003) were not observed. Of each animal with WLD an affected hoof was selected for the microbiological and histological evaluation. Cultures of horny tissue in Agar Sabouraud – Dextrose more Chloramphenicol under anaerobic conditions were carried out. The fungal identification considered the macroscopic features of the colony and the microscopic morphology. 28 positive isolations were obtained, of which 10 corresponded to pathogenic fungus (Scopulariopsis spp. Trichophyton tonsurans, Trichophyton verrucosum and Trichophyton schoenlii). For the histological observations, the technique of standard section of paraffin was used with previous softening of the samples in nitric acid. In all the hooves a degenerative process of the horny tissue was observed, being 9 the cases associated to bacterias and 4 the cases with combined presence of fungus and bacterias. The histologic exam allowed to determine lesion grades in function of the affected horny stratum. Key Words: Equines, hooves, fungus, horny tissue.
