“…Reports of deep infections in cats include nasal (80), renal (81), and ocular (82) involvement, as well as cerebellar infection (83). Cutaneous, subcutaneous, and systemic phaeohyphomycoses due to Cladophialophora bantiana, Phialophora verrucosa, Fonsecaea pedrosoi, Exophiala spinifera, Alternaria alternata, and A. infectoria have been documented in cats (79,(84)(85)(86)(87)(88)(89)(90)(91)(92).…”

SUMMARYEmerging fungal diseases due to black yeasts and relatives in domestic or wild animals and in invertebrates or cold- and warm-blooded vertebrates are continually being reported, either as novel pathogens or as familiar pathogens affecting new species of hosts. Different epidemiological situations can be distinguished, i.e., occurrence as single infections or as zoonoses, and infection may occur sporadically in otherwise healthy hosts. Such infections are found mostly in mammals but also in cold-blooded animals, are frequently subcutaneous or cerebral, and bear much similarity to human primary disorders. Infections of the nervous system are mostly fatal, and the source and route of infection are currently unknown. A third epidemiological situation corresponds to pseudoepidemics, i.e., infection of a large host population due to a common source. It is often observed and generally hypothesized that the susceptible animals are under stress, e.g., due to poor housing conditions of mammals or to a change of basins in the case of fishes. The descriptions in this article represent an overview of the more commonly reported and recurring black fungi and the corresponding diseases in different types of animals.

“…24 The bioavailability of itraconazole is affected by variations in diet and gastric pH, 25 and the drug has been associated with various adverse effects including anorexia (≤ 15% of dogs), 26 gastrointestinal disturbance, 25 and rare cases of hepatotoxicosis. 25,27 Fluconazole has been suggested as the treatment of choice for various CNS fungal infections in dogs. 8,9 However, voriconazole has a broader spectrum than fluconazole and itraconazole and is reported to be 50 to 100 times as potent against certain fungal species and also to have excellent bioavailability and ability in penetrating the brain and CSF.…”

Intracranial phaeohyphomycosis in small animals is rare and is most commonly associated with Cladophialophora infection. Phaeohyphomycosis frequently causes a focal granuloma, whereas other fungal infections typically cause diffuse meningoencephalitis. In all previous reports of phaeohyphomycosis of the CNS in dogs, treatment has been limited to medical management with conventional antifungal drugs and had failed to prevent death. The present report suggested that combined management of granulomas with surgery and newer triazole medications such as voriconazole may represent a novel strategy that improves the prognosis for this disease.

“…However a special case exists for the use of alternariosis in animals for the reasons mentioned here. All 12 previous feline cases with this disease pattern reported in the UK literature have been caused by Alternaria 5–7 . The term alternariosis has been used previously in the veterinary scientific literature 5 .…”

“…In Europe, there have been a number of case studies describing phaeohyphomycotic infection by Alternaria spp. (UK) 5–7 and the Netherlands 8 , Exophiala and Ulocladium (UK) 9,10 and a variety of other organisms from Spain 11 and Italy 12,13 . Although well recognized, there have been only a few reports of dermatophytic pseudomycetoma, usually in Persian cats 14,15 …”

IDEXX Laboratories database of cases submitted from the UK between March 2005 and February 2008 (36 months) was investigated for feline nodular granulomatous skin disease associated with fungal infection. Cytological and/or histological slides were reviewed and the diagnosis was based on the microscopic pattern of the inflammatory response and morphology of the causative organism. Aetiological diagnoses were hyalohyphomycosis (64 of 77 cases), phaeohyphomycosis (five of 77 cases) and dermatophytic pseudomycetoma (eight of 77 cases). All cases of hyalohyphomycosis were suspected to be alternariosis based on common features including anatomical distribution of lesions (48 of 64 cases involved the nostril and bridge of nose, face and ears), pattern of histological changes, morphology of the causative organism and results of fungal culture (Alternaria three of 16 and 'saprophyte' nine of 16 cases). Cases of phaeohyphomycosis were demographically and histologically similar to those of alternariosis, except the causative organisms were deeply pigmented brown and had a variety of morphologies that were different from Alternaria. Dermatophytic pseudomycetomas had a characteristic histological pattern including the presence of fungal microcolonies or grains within the tissue. These occurred most often on the trunk (five of eight cases) and four of eight cases were in Persian cats. These findings indicate that alternariosis is by far the most common nodular fungal skin disease of cats in the UK.
