Resumen:
Pheohyphomycosis is a disease caused by different dematiaceous fungi that occurs
in animals and man, causing skin or systemic granulomas, mainly
under immunosuppressive conditions. A case of systemic phaeohyphomycosis is described.
caused by Cladophialophora bantiana occurred in a dog diagnosed at the Laboratory
of Animal Pathology (LPA) of the Veterinary Hospital (HV) of the Federal University of
Campina Grande (UFCG), Patos, Paraíba. The disease occurred in a canine, female, of the
Pit Bull breed, 1 year old, lean body status, external mucous membranes
pale and enlarged lymph nodes. Ticks were also observed,
she had a lesion on her right forelimb and had recently given birth. during the routine
clinica, the animal had seizures and died. At necropsy,
nodular lesions were observed in the liver, kidneys and brain. Fragments were collected from the
lesions for histopathological and microbiological examination. On histopathological examination, the
lesions were similar, characterized by hepatitis, nephritis, and meningoencephalitis
granulomatous and necrotizing, multifocal to coalescent, associated with diadematid fungi
intralesional. In the microbiological examination, Cladophialophora bantiana was isolated. This is
the main agent involved in cases of central nervous system involvement,
because it has a neurotropic character. Phaeohyphomycosis is a rare disease
diagnosed in dogs at LPA/HV/UFCG, characterized by the systemic form, affecting
mainly the liver and brain, and should be included in the differential diagnosis
of liver and encephalopathies of dogs in the region.
