| ABSTRACT: Bee envenomation is frequent in humans and dogs, but uncommon in horses. This study aimed to describe a case of acute renal failure following mass envenomation in a horse. A mare was attacked by a swarm of bees and showed reluctance to move, epistaxis, and dark-brown urine. Biochemical exams revealed increase in urea and creatine serum levels. The mare did not respond to treatment and euthanasia was elected after four days of clinical course. At the necropsy, there were multifocal pinpoint to elevated skin lesions associated with edema and hemorrhage, which extended to the subcutaneous tissue and skeletal muscle, and the kidneys were diffusely dark-brown and friable. Microscopically, renal tubules were distended and filled with an orange-red,... |

| ABSTRACT: The objective of this paper is to report the epidemiological, clinical, and pathological aspects of a case of rumenitis due to the ingestion of soybean oil in a bovine. The ox had access to barrels that stored soybean oil and ingested an indeterminate amount of the product. After consuming it, the animal presented hiporexia; liquid, brownish, and greasy feces; severe dehydration (12%); apathy; sternal recumbency; and death with a clinical evolution of 4 days. At necropsy, the rumen was filled with voluminous food and moderate amount of white-gray liquid with a greasy appearance. Upon microscopic examination, hydropic degeneration of the epithelium and areas of mucosal necrosis were observed in the rumen and reticulum. From these findings, we... |

| ABSTRACT: A carcinoid is a rare neoplasm derived from neuroendocrine cells that may arise in the hepatobiliary system. This report described two cases of carcinoid of the gallbladder in dogs, with emphasis on the clinical, pathological and immunohistochemical aspects. Case 1 was a 10-year-old female Shih Tzu, with a history of prostration and occasional episodes of diarrhea and vomiting. Case 2 was a 10-year-old male Cocker Spaniel, with a history of diarrhea and abdominal pain. Abdominal ultrasonography suggested a neoplasm of the gallbladder in both cases. The dogs underwent cholecystectomy, and 10% formalin-fixed samples were sent for pathological examination. Histologically, a neoplastic proliferation of neuroendocrine cells was observed in the... |

| ABSTRACT: Meningiomas are neoplasms that commonly involve the central nervous system of cats, while cholesteatomas are nodular granulomatous chronic lesions within the choroid plexus that are rarely reported in cats. This study described a case of cholesteatoma and non-communicating hydrocephalus associated to a third ventricle meningioma in a cat. Clinically, the cat had a 2-year history of behavioral changes, photophobia and motor incoordination. At the necropsy, a tan-brown mass totally occluded the third ventricle, causing a severe dilation of the lateral ventricles (non-communicating hydrocephalus). Microscopically, the mass was composed by a neoplastic proliferation of spindle cells arranged in bundles, containing in the center psammomatous bodies... |

| ABSTRACT: Abomasal bloat associated with Sarcina genus bacteria is a rare condition reported in young ruminants. An outbreak characterized by the sudden death of eight lambs from a total of 80 lambs (30 days-old) occurred on a property located in the city of Palmares do Sul in the state of Rio Grande do Sul. Deaths began to occur after the introduction of supplementation into the diet of lambs. At necropsy, the abomasum was distended by gas and had diffusely thickened walls and emphysema. On microscopic examination, the abomasum showed marked diffuse emphysema and multifocal areas of mild superficial necrosis with many coccoid structures measuring approximately 2µm in diameter, arranged in tetrads, compatible with Sarcina genus bacteria. After removing... |

| ABSTRACT: Cryptococcus gattii is often associated with pulmonary and systemic infections in humans and animals. In this research we report a case of nasopharyngeal cryptococoma caused by C. gatti in an equine. A 10-year-old mare presented a mass obstructing the oropharynx. Macroscopically the mass was asymmetric, and was attached to the ethmoidal sinuses and obstructed the oropharynx. Histopathological examination of the mass revealed multiple yeast cells ranging from spherical to oval, 4-8μm in diameter, with some of them showing narrow base polar budding. Cryptococcus gattii growth in mycological culture (Sabouraud Dextrose Agar) and was L-canavanine-glycine-bromothymol blue Agar positive. The molecular identification confirmed the isolate as C. gattii... |

| ABSTRACT: Neuroblastic tumors can originate from the central neuraxis, olfactory epithelium, adrenal medullary region or autonomous system. Ganglioneuroblastoma are a type of neuroblastic tumor, with very few case descriptions in animals. Diagnosis of facial nerve ganglioneuroblastoma was made in a feline leukemia virus-positive 11-month-old cat. The cat had hyporexia, left head tilt, depressed mental state, horizontal nystagmus, inability to retract the pinched left lip, anisocoria, ptosis, and absence of the menace reflex. Gross necropsy showed a mass at the left facial nerve root region. Histological examination of this mass showed neoplastic proliferation of neuroblasts arranged in a cohesive pattern and mature ganglion cells. Ganglion cells were... |

| ABSTRACT: In this work, we describe an unusual case of fibrinous pleuropneumonia caused by Pasteurella multocida associated with generalized lymphadenomegaly in a bovine. The animal had a one-month history of generalized superficial lymphadenomegaly that progressed to anorexia and submandibular oedema, resulting in spontaneous death. At necropsy, the parenchyma of the lymph nodes and multiple organs was obliterated by a dense proliferation of round neoplastic cells (lymphoma). Additionally, the neoplasm presented multifocal areas of haemorrhage and necrosis, characteristic of lymphoma. The parietal and visceral pleura and parietal pericardium were enlarged and covered diffusely with large amounts of a yellowish fibrillary material. The lungs were mildly... |

| ABSTRACT Bacillus anthracis strain SPV842_15 was isolated from bovine fetus, while B. anthracis strain Brazilian vaccinal was recovered from a commercial vaccine. We report here the genome sequences of both strains. The SPV842_15 genome is composed of a single circular chromosome with a length of 5,228,664 base pairs, and comprises 5911 coding sequences. In turn, the Brazilian vaccinal genome remains in 201 contigs with 5733 coding sequences. Both genomes have an overall C + G content of 35.4%, and 11 genes encoding the ribosomal RNAs (rRNAs) 5S, 16S and 23S. Only the plasmid pX01 sequence, which carries genes for toxins synthesis, was detected and completely assembled for both strains. These plasmids have a length of 181,684 base pairs and a C + G content... |

| Descrevem-se casos de intoxicação aguda por cobre em ovinos da raça Santa Inês, numa propriedade rural, no Rio Grande do Sul. Três ovelhas recém-paridas, que consumiam ração formulada para bovinos, ingeriram, avidamente, sal mineral comercial para bovinos e apresentaram doença clínica e morte, uma semana após a introdução do sal. Os animais desenvolveram anorexia, permaneceram em decúbito lateral, o qual evoluiu para esternal e apresentaram fasciculação e rigidez muscular generalizada, antes de morrerem. À necropsia de um desses animais, as principais alterações foram hepatomegalia moderada e acentuação do padrão lobular hepático, além de erosões e ulcerações multifocais aleatórias na mucosa abomasal. Na avaliação histológica do fígado, havia necrose... |

| ABSTRACT: Equine multisystemic eosinophilic epitheliotropic disease (MEED) is a rare disease, characterized by eosinophilia and eosinophilic infiltration of several organs. A 5-year-old horse presented pruritus, areas of alopecia, and moderate eosinophilia. The horse was treated with corticosteroids and antibiotics without substantial improvement; and after the disease progressed to fever, diarrhea, gastric reflux and progressive weight loss. Due to poor prognosis the horse was euthanized. Necropsy revealed poor body condition, multiple to coalescing foci of alopecia, with epidermal ulcerations and crusts on the head and distal parts of the limbs. The proximal duodenum was enlarged, with 3 intraluminal nodules. Histopathological evaluation revealed... |

| ABSTRACT: Scirrhous eosinophilic gastritis (SEG) is characterized by diffuse infiltration of eosinophils and concomitant fibrovascular tissue proliferation in the stomach wall. The condition is a rare occurrence with an unknown cause. Two dogs were examined with a history of progressive weight loss, emesis, melena and anorexia. Complete blood cell counts of both cases revealed anemia and eosinophilia, while ultrasonography examination revealed thickening of the stomach wall. Due to suspected gastric neoplasia and a poor clinical prognosis, the dogs were euthanized. At necropsy, both had markedly distended stomachs with a diffusely thickened and firm wall. The spleens of both dogs were enlarged with a nodular surface. Histological evaluation revealed... |
