“…The clinical signs presented by the goat, as well as the gross and histological findings observed in the lungs, are similar to those described by other authors in domestic animals (GUTIÉRREZ & MARÍN, 1999;KOMMERS et al, 2005;LEMOS et al, 2007;LUVIZOTTO et al, 2009;GALIZA et al, 2014). In goats, the lungs appeared to be the major organs affected by cryptococcosis (BARÓ et al, 1998), and the lesions observed in this goat explain the dyspnea, cough and nasal discharge.…”

This report describes the clinical, pathological, and molecular aspects of a pneumonia by Cryptococcus neoformans in a goat in the Southern region of Brazil. A goat with a history of prolonged transportation presented dyspnea, nasal discharge and cough, and was subjected to necropsy, histopathology, and mycological evaluation. Grossly, cranio-ventral pulmonary consolidation was observed, characterized by firm and grayish areas interspersed with dark red foci. Histopathology of the lungs showed areas of parenchymal necrosis, containing blastoconidia with a slightly basophilic central cell, surrounded by an unstained capsule. It was associated with moderate granulomatous inflammatory infiltrate and peripheral fibrosis. The capsule and fungus cell exhibited marked Alcian Blue and periodic acid-Schiff staining, respectively. Diagnosis of fungal pneumonia by C. neoformans was based on clinical, pathological, and molecular findings.

“…Os diagnósticos das micoses e de pitiose foram realizados com base na histomorfologia do agente através da coloração de hematoxilina-eosina (HE) e outros métodos histoquímicos, incluindo os métodos do azul Alciano, do ácido periódico de Schiff (PAS) e da impregnação pela prata de Grocott (GMS); ou pela histomorfologia do agente e por exames adicionais, incluindo cultura micológica/microbiológica, imuno-histoquímica (IHQ) e reação em cadeia de polimerase (PCR), ou combinações desses métodos. Alguns casos deste levantamento foram previamente publicados como relatos de casos ou estudos de compilações de casos, incluindo, por exemplo, as seguintes publicações: Rech et al (2004), Segabinazi et al (2004), Kommers et al (2005), Gabriel et al (2008), Trost et al (2009) e Ceolin et al (2012. A pitiose foi a doença com maior número de diagnósti-cos, seguida por candidíase, aspergilose, zigomicose, dermatofitose, malasseziose, criptococose, esporotricose, rinosporidiose, pneumocistose e histoplasmose (Quadro1).…”

glaukommers@yahoo.com A retrospective study was performed to determine the main mycoses and oomycosis that affected domestic animals diagnosed in the Laboratório de Patologia Veterinária (LPV) of the Universidade Federal de Santa Maria (UFSM). A total of 29,686 exams (9,487 necropsy reports and 20,199 biopsy reports) performed between January 1990 and December 2012 were analyzed. Two hundred and thirty cases (78% of mycoses and 22% of pythiosis) were found. Data about epidemiology, clinical signs, gross and histologic lesions were obtained from the reports. In two cases the fungi observed were not identified. The main diseases observed, in descending order of prevalence, were: pythiosis, candidiasis, aspergillosis, zygomycosis, dermatophytosis, mallasseziosis, cryptococcosis, megabacteriosis, and sporothrichosis. Others diseases with only one cases each were histoplasmosis and pneumocystosis. Pythiosis affected mainly horses and the mycosis affected mainly companion animals (dogs and cats).INDEX TERMS: Mycoses, pythiosis, domestic animals, veterinary pathology.

“…No Brasil há relatos de C. neoformans e C. gattii isolados em áreas urbanas e de mata, assim como casos clínicos em humanos (Côrrea et al 1999, Montenegro & Paula 2000, Fortes et al 2001) e animais (Kommers et al 2005, Martins et al 2008, Riet-Correa et al 2011. A infecção ocorre principalmente pelo trato respiratório, através da inalação de leveduras ou basidiósporos e as lesões ocorrem principalmente na cavidade nasal e nos pulmões (Castellá et al 2008).…”

Pesq. Vet. Bras. 34(3):261-269, março 2014 261 RESUMO.-Sete casos de criptococose (seis gatos e um cão) foram estudados para estabelecer as características histomorfológicas e histoquímicas determinantes no diagnóstico histopatológico dessa condição. Os dados complementares relacionados à epidemiologia, aos aspectos clínicos, à localização das lesões e às alterações macroscópicas foram obtidos dos protocolos de necropsias e biópsias. Na histologia, as leveduras foram observadas no interior de macrófagos ou livres no parênquima, associadas à reação inflamatória linfo-histioplasmocítica que variou de escassa a acentuada. Pela técnica de hematoxilina-eosina (HE) as leveduras eram arredondadas, com célula central contendo um núcleo, circundada por um halo claro (cápsula geralmente não corada). As técnicas histoquímicas do ácido periódico de Schiff (PAS), Grocott e Fontana-Masson (FM) foram utilizadas e evidenciaram a parede das células das leveduras. Pelo FM observou-se a melanina presente nessas células. As téc- Seven cases of cryptococosis (six cats and one dog) were studied to establish the determining histomorphological and histochemical characteristics in the histopathological diagnosis of this condition. Additional data related to the epidemiology, clinical aspects, sites of the lesions, and gross findings were obtained from the necropsy and biopsy protocols. Histologically, yeasts were observed inside macrophages or free in the parenchyma, associated with scarse to severe lymphohistioplasmacytic inflammatory reaction. In the hematoxylin-eosin (HE) sections, the yeasts were round, with a central cell containing a nucleus, surrounded by a clear halo (usually non-stained capsule). The techniques of periodic Schiff acid (PAS), Groccot (GMS), and Fontana-Masson (FM) were utilized and demonstrated the wall of the yeast cells. The FM stain showed the melanin present in these cells. The Alcian blue and Mayer's mucicarmin stains showed mainly the yeast polysaccharide capsule. The diameter of the cells ranged from 1.67 to 10.00µm and the full diameter of the encapsulated yeasts varied between 4.17 e 34.16µm. Yeast buddings were better observed through the PAS stain and were narrow based, simple or multiple, mainly in the opposite poles of the cells or forming chains. The definitive diagnosis of cryptococosis was established through the histopathological exam, based on the specific morphology of the agent (encapsulated yeast) and on histochemical proprieties, mostly in the cases without fungal culture.
