| The aim of this study was to investigate the effect of bark extract Bathysa cuspidata (BCE) in the reconstitution of hepatic parenchyma and stroma after dysfunction induced by the CCl4. Liver lesions were induced by intraperitoneal administration of CCl4 (1 mL/kg) every 48 h for 12 days. The animals were treated with B. cuspidata extract (BCE) administered by gavage for another 12 days. Forty-nine rats were randomized into seven treatment groups with seven animals receiving CCl4, BCE (200, or 400 mg/kg) and the vehicle DMSO alone, or in different combinations. The extract alone showed no evidence of hepatic toxicity. In general, rats acutely exposed to CCl4 without the treatment with BCE presented high ALT and AST serum levels and high tissue content of... |

| The literature indicates that acute pancreatitis is a complication of massive hemolysis with a prevalence of about 20%. We describe an experimental model of hemolysis-induced acute pancreatitis. Hemolytic anemia was induced in rats by a single ip injection of 60 mg/kg of 20 mg/ml acetylphenylhydrazine (APH) in 20% (v/v) ethanol on the first experimental day (day 0). One hundred and fifty Wistar albino rats weighing 180-200 g were divided into three groups of 50 animals each: groups 1, 2 and 3 were injected ip with APH, 20% ethanol, and physiological saline, respectively. Ten rats from each group were sacrificed on study days 1, 2, 3, 4 and 5. Serum amylase, lipase levels and pancreatic tissue tumor necrosis factor-alpha (TNF-alpha) and platelet-activating... |

| Complement-depleted and -non-depleted BALB/c mice were inoculated with Leishmania (Leishmania) amazonensis promastigotes into the hind footpad to study the role of the complement system in cutaneous leishmaniasis. Total serum complement activity was measured by hemolytic assay and C3 fragment deposit at the inoculation site was determined by direct immunofluorescence in the early period of infection, i.e., at 3, 24, 48 h and 7 days post-infection. The inflammatory reaction and the parasite burden were evaluated in the skin lesion at 7 and 30 days post-infection. Total serum complement activity decreased in the early phase of infection, from 3 to 24 h, in non-depleted mice compared to non-infected and non-depleted mice. C3 fragment deposit at the site of... |

| ABSTRACT: Renal cell carcinoma, especially with extensive involvement of peritoneal cavity, is rarely described in horses. This study described a case of renal cell carcinoma in an 8-year-old mare, which presented with an enlargement in the left flank, decreased appetite and straining to defecate. Clinically, a tumor in the left retroperitoneal space was detected by rectal examination and ultrasonography. The animal died after one month of clinical evolution. At necropsy, the left kidney was completely effaced by a 50cm in diameter, irregular, round, lobulated cystic mass with necro-hemorrhagic areas. Within the peritoneal cavity, there was severe hemoperitoneum and numerous sessile and pedunculated masses ranging from 2.0 to 15.0cm diameter that were... |

| 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,... |

| Eight pregnant mixed breed bitches, serologically negative for Toxoplasma gondii, were divided into three groups. Group I : bitches 01 and 02 (1.0 x 10(7) tachyzoites of Toxoplasma gondii, subcutaneous route); Group II: bitches 03, 04 and 05 (1.5 x 10(4) oocysts, oral route); Group III: bitches 06, 07 and 08 (as control). Clinical and obstetric examinations were conducted twice a day on each bitch, and weekly ultra-sonografic evaluations were performed until the end of pregnancy. From the 2nd day the bitches presented clinical alterations such as fever, nasal flowing, lachrymation, prostration, lymphadenopathy, premature parturition, abortion and fetal death. In Group I, Toxoplasma gondii was isolated from the bitches urine (day 10) and saliva (day 18).... |

| ABSTRACT: 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... |

| ABSTRACT: This study described the pathological and microbiological aspects of a fatal systemic Mortierella wolfii infection in a neonatal calf in southern Brazil. The calf was born clinically normal, but on the third day of life it presented apathy, unilateral hypopyon, and neurological signs, and in the next day it was euthanized. At necropsy, multiple soft, and white-yellow nodules were observed in the liver, spleen, kidneys, mesenteric lymph nodes, heart, and lungs. In the brain, reddish, and friable areas were found. In the eye, there were anterior and posterior synechiae, diffuse thickening of choroid, and anterior chamber filled by whitish and friable material. Microscopically, areas of necrosis, pyogranulomatous inflammation, vasculitis,... |

| ABSTRACT: This study described the epidemiological, clinical, pathological and bacteriological aspects of Mannheimia haemolytica pleuropneumonia in goats associated with shipping stress. Forty goats transported from the Northeast to the Southern region of Brazil died during shipment, or 2-3 days after unloading. Clinical signs included dyspnea, mucopurulent nasal discharge, and coughing. All goats were necropsied, and multiple tissues were collected for histopathological analysis and involved agent identifications. All lungs showed pulmonary consolidation, predominantly affecting the cranioventral lobes, in addition to the marked fibrinous pleuritis, pleural thickening, and pleural adhesions, that affected 90% of the goats. Histologically, there was... |

| ABSTRACT: The Guiana dolphin (Sotalia guianensis) is a small odontocete distributed from Santa Catarina state, Brazil, to Honduras. Although it is currently considered “near threatened” by the International Union for Conservation of Nature, considerable knowledge on health and disease aspects of this species has been gained over the last decade. The main threats for the species are represented by multiple anthropic factors. Guiana dolphins feed on a variety of taxa, primarily teleosts, crustaceans, and cephalopods. Herein, we reported a case of severe laryngeal displacement and esophageal impaction with ulceration associated with a deglutted adult leatherjacket (Oligoplites sp.). This fish species is not a common prey item of Guiana dolphins’ diet. Severe... |

| Fifteen mature crossbred sheep were fed different daily amounts (2.5-35g kg-1 bw) of the fresh green leaves of Ateleia glazioviana for different periods of time (1-24 days). One sheep was not fed the plant and served as a control. All 16 sheep were euthanatized at different stages of the experiment, necropsied, and several organs, including heart and brain were evaluated histologically. Samples of five brain regions from three affected sheep were evaluated by electron microscopy. Clinical signs observed in three sheep included depression, anorexia, general weakness, staggering gait and prolonged recumbency. One sheep had signs of congestive heart failure. Necropsy findings included subcutaneous dependent edema and edema of the body cavities in two sheep... |

| ABSTRACT: Protozoal diseases caused by species of Sarcocystiscan cause serious damage in sheep flocks, inducing decreased growth conversion rates and partial or complete loss of carcasses at the slaughterhouse. This article describes an outbreak of Sarcocystis giganteainfection in sheep slaughtered in a farm in Rio Grande do Sul State, Brazil. Between July and September 2013, three sheep showed multiple nodules in the esophagus that were microscopically characterized as encapsulated cysts filled with elongated, basophilic, nucleated structures morphologically consistent with S. giganteabradyzoites. Diagnosis was made based on the epidemiological, macroscopic, and microscopic findings. This is the first report of this infection in sheep in Rio Grande do... |

| ABSTRACT: Nematodes of the superfamily Metastrongyloidea affect the respiratory, cardiovascular, and nervous systems of domestic carnivores and are uncommonly detected in wild animals. This report describes the lesions associated with pulmonary parasitism by nematodes of the superfamily Metastrongyloidea in a wild crab-eating fox ( Cerdocyon thous ) in the Federal District, Brazil. Grossly, there was pulmonary hyperemia, edema, and emphysema. Microscopically, there was granulomatous arteritis associated with intravascular metastrongylid. The anatomical location, characteristic lesion, and histological features of the parasite suggested that the nematode involved in this case is Angiostrongylus vasorum . This worm is frequently reported parasitizing... |
