RESUMO
Background: Narcolepsy is a neurologic sleep disorder, in humans characterized by excessive and recurrent daytime sleepiness, rapid eye movement in the beginning of the sleep, in association with hypnagogic hallucinations and sleep paralysis, with or without cataplexy. In dogs, the characteristic symptom is cataplexy and narcolepsy exists in two forms, one genetic and one acquired. This article describes one case of narcolepsy as a symptom due to an adenohypophysis tumor.Case: Dog presenting progressive signs of appetite loss, incoordination and constant falling. At clinical evaluation, the dog presented cachexia, hipocolored mucosae and compulsively walking in circles to the right, the four limbs collapsed from physical exhaustion, remaining in a narcoleptic state. Complementary exams, like x-ray, ultrasonography, hemogram and biochemical examination did not show signifi cant alterations. The patient was hospitalized for recovery of general status and corticoid treatment was initiated, but after two days it died. Necropsy reported that the cause of death was 180º gastric torsion and adrenals presented diffuse and marked enlargement of the cortical layer, 1.5 cm diameter neoplasia at the base of the brain and 0.5 cm diameter cavitation in the cerebral parenchyma. In the microscopic examination, adrenals were hyperplastic at the cortical region and there was round cell prolifera

RESUMO
Background: Aspergillosis is the most common mycosis in birds, which are considered potential host also susceptible to the infection by Aspergillus spp. The clinical signs of the disease are often related to the respiratory tract, although other organs or systems may be affected. Signs are generally either not specifi c or may be directly related to the extent of the lesions in the respiratory tract (rhinitis, changes in the vocalization and dyspnea). The aim of this study was to describe and characterize three cases of aspergillosis in Greenwinged saltators (Saltator similis), based on reference standard diagnostics of this mycosis.Cases: Three Green-winged adult male saltators that had been participating weekly for three months in bird singing contests were referred to a private veterinary clinic. The clinical evaluation revealed pronounced hoarseness (3/3) and intense dyspnea (1/3). The animals were allocated to a warmed (280 C) oxygen chamber at 65% relative humidity. All birds were nebulized with saline solution and hyaluronidase. In addition, the birds were treated orally with complex vitamins B, A, D and E and intravenously either with dexamethasone and doxycycline (Case 1), azithromycin (Case 2) or metronidazole-enrofl oxacin combination (Case 3), in association with the use of Arnica Montana CH6 in the drinking water, and fl uid therapy (5% glucose, Ringer-lactate and

RESUMO
Background: Caseous lymphadenitis (CL), an infectious disease of sheep and goats caused by Corynebacterium pseudotuberculosis, is characterized by pyogranulomas, white to greenish-yellow contents with aspect of rennet-coagulated cheese, and concentric laminations. Transmission occurs through direct contact with animals showing superfi cial lesions, via iatrogenic, or by respiratory route from aerosols. This paper reports the association of pyogranulomatous spondylitis with caseous lymphadenitis in two sheep, in Rio Grande do Sul State, southern Brazil.Cases: Two male sheep, 7- and 6-months-old, Texel (lamb 1) and mixed Texel (lamb 2), respectively, were submitted to necropsy. Affected sheep were reared under semi-intensive system in the same group, and had not been tail-docked. Both lambs showed weakness, diarrhea and paralysis of hind limbs. At necropsy, sheep had good body conditions, pale mucous membranes and large numbers of Haemonchus sp. worms within the abomasum. Lamb 1 showed serous fat atrophy and two abscesse-like lesions, one measuring 3.0 cm in diameter in the left apical lung lobe and other affecting the last lumbar vertebrae body. In lamb 2 there were three lesions like abscesses, a thoracic lesion involving the 13th vertebrae and the 1st lumbar vertebrae, a 3.0 cm in diameter lesion in the left axillary region, and a 1.5 cm lung lesion in the left apical lobe, ap

RESUMO
Background: The nasal mites of the Rhinonyssidae family include the highest diversity of mandatory hematophagous endoparasites of the respiratory system of birds. In general, these mites cause no significant lesions, except Sternostoma tracheacolum that invades the trachea, lungs and air sacs and may compromise breathing in birds. This study reports the death of a Belgian canary (Serinus canaria domestica) due to the parasitism by S. tracheacolum with an aggravating and concurrent pododermatitis infection.Case: A Belgian canary from a commercial bird flock, in which a high mortality rate had lately been recorded, was submitted to necropsy. Multiple blackened foci (1.0 mm in diameter) present in the trachea and the air sacs were subsequently identified as Sternostoma tracheacolum mites. Microscopically, there were diffuse and moderate infiltrates of lymphocytes, plasma cells, macrophages and heterophils within the tracheal submucosa and areas of fibrosis and osseous metaplasia of the tracheal cartilage. In the air sacs, there were multiple yellowish-brown foci of caseous necrosis, which were surrounded by inflammatory infiltrate of macrophages and multinucleated giant cells. In the lungs, there were foci of caseous necrosis surrounded by macrophages. In the tracheal lumen, mites sections were observed. Clusters of nucleated erythrocytes and brown granular pigment were seen withi

RESUMO
Thirteen cases (8.44%) of feline urologic syndrome were diagnosed in 154 necropsies carried out in cats from 1991 to 1997. Epidemiological data, clinical signs, gross, and histopalhological features were reviewed. Seven cats were intact males and six were castrated males. Urethral obstruction, hematuria, dysuria, and urinary bladder distention were the main clinical signs. Main gross and histopathological findings were hemorrhagic cystitis, pyelonephritis, perirenal edema, hydronephrosis, tubular necrosis, urethritis.
