> Abstract
> Bilateral exudative chorioretinitis was diagnosed in an 18-month-old male neutered ferret (Mustela putorius furo) with a generalized Cryptococcus gattii infection confirmed by PCR. The animal was referred to the Ophthalmology Service of the Autonomous University of Barcelona (VTH-UAB) for acute onset blindness. Complete ophthalmic examination revealed absent menace response and dazzle reflex in both eyes (OU), as well as subretinal edema located in the tapetal fundus. At that time, the clinical ophthalmologic diagnosis was bilateral exudative chorioretinitis. Treatment with prednisone (0.5 mg/kg PO q24 h) was instituted in addition to the ongoing treatment with fluconazole (10 mg/kg PO q24 h). The following rechecks revealed secondary cataracts with subsequent lens subluxation and panretinal degeneration OU. Despite being blind and the poor prognosis of disseminate cryptococcosis, the patient remained active and in good body condition during 6 months after the initial diagnosis. At that time, the ferret showed ataxia, incontinence, and generalized pain. A magnetic resonance imaging study revealed a mass affecting the spine. The owners declined further investigations and the ferret was humanely euthanized. The postmortem histopathology confirmed the initial diagnosis of cryptococcosis and the presence of intraretinal Cryptococcus spp. To the authors' knowledge, this is the first report of Cryptococcus spp. induced exudative chorioretinitis in a ferret.

> Abstract
> The role of wild and free-roaming domestic carnivores as a reservoir of Leishmania infantum was investigated on the Mediterranean island of Mallorca (Balearic Islands, Spain), an endemic area for this disease. Serum, blood and/or spleen samples from 169 animals [48 dogs from a kennel, 86 wild-caught feral cats, 23 pine martens (Martes martes), 10 common genets (Genetta genetta) and two weasels (Mustela nivalis)] were analysed. Seroprevalence determined by Western blotting was 38% in dogs and 16% in feral cats, while the prevalence of infection determined by PCR was 44% in dogs, 26% in cats, 39% in pine martens and 10% in genets. This is the first report of infection by L. infantum in the pine marten or any other member of the Mustelidae family. Restriction fragment length polymorphism (RFLP) analysis found 33 different patterns in 23 dogs, 14 cats and three martens. Two patterns were shared by dogs and cats, two by different cats, and one by different dogs. Patterns were different to those previously reported in carnivores from peninsular Spain. No external lesions compatible with leishmaniasis were observed in any species other than the dogs. Although the dog is probably the primary reservoir of leishmaniasis in endemic areas, the prevalence and the absence of apparent signs of this disease within the island's abundant feral cat and pine marten populations could make these species potential primary or secondary hosts of L. infantum in Mallorca.
