Background: Cryptococcosis is a mycosis that primarily affects domestic cats and is caused by fungi of the genus Cryptococcus, resulting in cutaneous, ocular, respiratory, and neurological manifestations. Diagnosis is based on the microscopicevaluation of the lesions and isolation of the causative agent. The aim of this study was to describe a case of feline cryptococcosis diagnosed by cytology and treated at the Veterinary Hospital of the State University of Santa Cruz (HV-UESC).Case: A 5-year-old uncastrated male cat was taken to the HV-UESC small animal clinic, owing to a gradual increase inthe volume of the nasal plane spanning over a year, accompanied by respiratory distress. Upon physical examination, theanimal was found to have regular nutritional status, dehydration, hypocorous mucosae, and enlarged popliteal lymph nodes.In addition, multifocal areas of ulceration on the body as well as increased volume in the nasal plane (clown nose) wereobserved. Peripheral blood samples were collected for complete blood count and biochemical analysis. Due to clinicalsuspicion of fungal lesions, fine needle aspiration of the nasal lesion was performed and cytological slides were sent tothe HV-UESC histopathology laboratory. Probable diagnoses included rhinosporidiosis, cryptococcosis, and histoplasmosis. The animal was subjected to thoracic radiography in the imaging division of the HV-UESC. Blood counts revealedthrombocytopenia (130,000/mm3) and biochemical tests presented hypoproteinemia (3.2 g/dL), with hypoalbuminemia(1.52 g/dL); however, chest radiography did not show pulmonary alterations. Results of cytological analysis indicatedpyogranulomatous inflammation associated with intracellular organisms, demonstrating a pathogen morphology similarto that of Cryptococcus spp. Before the diagnosis, itraconazole1 5 mg/kg (1 capsule, twice a day for 30 days) and fipronil2(1 ampoule 0.5 mL, on the back) were prescribed...

Resumo

As aves são hospedeiras de uma rica microbiota fúngica que pode atuar como patógenos para o homem e outras espécies animais, acarretando, consequentemente, graves problemas de saúde pública. O objetivo do presente trabalho foi avaliar a participação das aves mantidas em criadouros na epidemiologia de doenças infecciosas como a criptococose, e aspergilose, verificando consequentemente a manutenção e propagação de patógenos no meio ambiente. Foram colhidas 36 amostras de excretas de passeriformes e processadas e cultivadas em Agar Sabouraud Dextrose 4% a temperatura ambiente e a 37° C. As colônias fúngicas isoladas foram classificadas de acordo com suas características morfológicas e tintoriais. Posteriormente, aquelas em forma de leveduras foram repicadas em Agar Níger, e incubadas a 30° C. Em uma amostra houve crescimento de mais de um tipo de colônia. Foi verificada a presença de 25,0% de Penicillium spp., 19,4% de Trichosporon spp., 13,9% de C. gattii, 11,1% de C. neoformans, 11,1% de Candida spp., 8,3% de Rhizomucor spp., 8,3% de Aspergillus spp., 2,8% de Nigrospora spp. e 2,8% de Geotrichum spp. Pelo exposto, concluise que os pássaros eliminam continuamente microrganismos patogênicos, em suas fezes atuando de forma definitiva na ecoepidemiologia de doenças infecciosas.(AU)


Birds are hosts for a rich fungal microbiota which can act as potent pathogens for humans and other species of animals, causing thereby serious public health problems. The objective of this study was to evaluate the participation of birds kept in containers in the epidemiology of infectious diseases such as cryptococcosis and aspergillosis, thus verifying the maintenance and spread of pathogens in the environment. 36 samples of excretas of passeriformes were collected and were cultivated in Sabouraud Dextrose Agar 4% at room temperature and 37°C. The isolated fungal colonies were classified according to their morphological and staining characteristics. Subsequently, those in yeast form were peaked in Niger Agar, incubated at 30°C. In one sample showed growth of more than one type of colony and there was verified the presence of 25.0% of Penicillium spp., 19.4% of Trichosporon spp., 13.9% of C. gattii, 11.1% of C. neoformans, 11.1% of Candida spp., 8.3% of Rhizomucor spp., 8.3% of Aspergillus spp., 2.8% of Nigrospora spp. and 2,8% of Geotrichum spp. It can be conluded by the expost that birds shed continuously pathogenic microorganisms in their feces acting in definitive form in the infectious diseases ecoepidemiology.(AU)
