Plain-English summary
A 3-year-old male mixed-breed cat was brought in with severe skin problems, including painful ulcers and crusty lesions on his face, chest, and front legs. This aggressive cat had scratched five people, three of whom developed symptoms of a skin infection. The infection was caused by a fungus called Sporothrix schenckii, which can be transmitted from cats to humans. The diagnosis was confirmed through skin tests and laboratory analysis. Treatment for the affected individuals included antifungal therapy, and the cat's condition improved with appropriate care.

Abstract
<abstract language="spa">La esporotricosis consiste en micosis profunda, de evolución subaguda o crónica decurrente de infección por el hongo dimorfico Sporothrix schenkii. Consiste en dermatopatia mucho frecuente en nuestro medio, resultante de la penetración de abrojos e de arañazos por espinos de plantas. El S. schenkii ha sido descrito, en S. Paulo, en perros, gatos, aseninos, bovinos, equinos y ratones. Todavía, el carácter de antropozoonosis de la enfermedad pocas veces ha sido descrito tanto en la literatura internacional como en la nacional, existiendo apenas una citación en lo Brasil, de probable transmisión gato/hombre. Se discrebió, en lo presente relato, caso clínico de esporotricosis felina con transmisión através de arañadura en propietario, tratador y médico veterinário. Un gato, sin raza definida, macho, con 3 años, mucho agresivo, con grave cuadro cutáneo (cefálico, torácico y de miembros torácicos) manifestado por lesiones ulceradas, exudativas de alopecia, deposición de crostas hemorrágicas, agraviado por síntomas de lo complejo respiratorio felino, donde por su temperamento agresivo habia arenado en corto espacio de tiempo 5 individuos, donde 3 de los individuos manifestaron sintomas de evolución y gravedad distintas. El diagnostico clínico presuntivo fue confirmado perlo examen histopatológico (H.E., PAS) de fragmentos de piel, linfonodos y amígdalas cogidos, "intra-vitam" y/o "post-morten", per lo aislamiento de lo agente, per la inoculación en testículos de ratas adultas y posterior nuevo aislamiento. Se confirmó la patologia por pruebas suerológicas (F.C., anticuerpos precipitantes) y prueba de intradermoreación (esporotriquina) en los pacientes acometidos.<br>The sporotrichosis is a deep mycosis, its course is subacute or chronic, and is caused by the Sporothrix schenckii. It's a very common dermatopathy, generally arising from thorn wounds, insects stings as well as from splinters. The S. schenckii has been described in São Paulo, Brazil, in canines, felines, asinines, bovines, equines and murines. However, its antropozoonotic feature has seldom been mentioned in the international literature, and, in Brazil, there is only one report about a possible transmission cat-human being. The current approach describes a clinical case of feline sporotrichosis transmitted by cat scratch to the owner, the career and the veterinarian.' A very offensive three-year-old male mongrel cat showed severe cutaneous lesions in cephalic, thoracic regions and forelimbs. These lesions were ulcerations, exsudation, crusts, alopecia worsened by the symptoms of the feline respiratory complex. This cat wounded, in a short time, 5 persons. Three of them had shown symptoms of distinct severity and development. The presumptive clinical diagnosis was corroborated by histopathology (HE, PAS) of skin, lymphonodes, and tonsils fragments obtained "intra-vitam" and "post-morten". This was true by the isolation of the agent. Finally, this was confirmed as a result of serological (FC, precipitation antibodies) and immunocutaneous (sporotrichina, histoplasmina) tests made in affected patients.
