Cerebral phaeohyphomycosis in a dog.

Cerebral phaeohyphomycosis was diagnosed in a 9-year-old spayed dog that had a series of epileptic convulsions a day before death. About 6 weeks before her death, she had been treated for severe demodectic mange. During this period, persistent leukopenia, lymphocytopenia, and thrombocytopenia were found by blood analyses. At necropsy, multiple large pyogranulomatous lesions were found in the cerebrum and meninges. Dematiaceous fungi with brown, branching, septate hyphae and budding yeasts were found within tissue cells and in the necrotic areas.

Canine protothecosis: review of the literature and report of an additional case.

A review of protothecosis in dogs revealed that this malady usually begins in the gastrointestinal tract and progresses to systemic involvement. Clinical signs generally include bloody diarrhea or blood-stained feces as well as blindness, ataxia, and polyuria. Histologically, myriads of protothecal organisms in different stages of development are found in the granulomatous lesions. Two main species have been culturally identified: Prototheca zopfii and P wickerhamii. In the absence of cultural studies, species identification can be accomplished readily by immunofluorescence. The present case involved P zopfii infection in a 5-year-old female Cocker Spaniel that had bloody diarrhea, with a history of bloody diarrhea 6 months earlier.

Mycotic infections of the alimentary tract of nonhuman primates: a review.

Lesions of candidiasis, mucormycosis (phycomycosis), entomophthoramycosis, geotrichosis, cryptococcosis, paracoccidioidomycosis and coccidioidomycosis have been reported in the alimentary tract of nonhuman primates. Candidiasis and mucormycosis were reported most often. Both Old and New World monkeys and great apes are susceptible; infection is rare in prosimians. Ulcers and necrosis of the mucosa of the alimentary tract are the principal gross lesions. A granulomatous inflammatory process occurs in which the fungi are visible histologically on hematoxylin and eosin (HE)-stained sections, but they are seen and characterized better when stained with periodic acid-Schiff (PAS) or Gomori methenamine silver (GMS) techniques. Cultural or immunofluorescence studies, or both, are necessary for specific identification of the fungi. Immunosuppression is suggested as a predisposing factor in certain mycotic diseases.

Hepatic trematodiasis in a Ganges River dolphin.

Hepatic trematodiasis caused by Cyclorchis campula was diagnosed in a juvenile Ganges River dolphin that had been in captivity at an aquarium for approximately 1 year. Histopathologic findings were severe chronic suppurative cholangitis, hyperplasia of the bile duct epithelium, and periductal fibrosis associated with fluke infection of the large bile ducts.
