Paraganglioma de corpo aórtico em cão / Aortic body paraganglioma in dog

Background: Aortic body paragangliomas are uncommon neoplasms that develop mainly in aortic and carotid bodies. It has been supposed that genetic factors and chronic hypoxia may stimulate tumor development. The brachycephalic dog breeds, as Boxer, are most predisposed to present this neoplasm. The clinical symptomatology is related to tumor size and localization. Usually aortic body paraganglioma has benign biological behavior, when it is malignant, rarely promotes metastases. The aim of this study was to report a case of the aortic body paraganglioma as death cause in a dog. Case: A canine, 10-year-old, male, cross breed, presented clinical signs as anorexia, emesis, cough, dyspnea and exercise intolerance. After death the animal was examined at the Department of Veterinary Pathology at the Federal Rural University of Amazonia. On necropsy, no pericardial effusion was identified, however pleural and abdominal effusion was observed, volume like 1000 and 700 mL, respectively. The heart had a neoplasm near the left atrium, it measured 6.5 x 8.2 cm, had irregular surface, firm consistency, grayish color, and at the cut showed infiltration in the myocardium, as well as obstruction of the left atrial lumen and left ventricle concentric hypertrophy. No distant metastases were found. Microscopically, the tumor consisted of polyhedral morphology cells, eosinophilic cytoplasm, spherical and hyperchromatic nucleus. Cells were grouped into lobes separated by fibrovascular stroma, large cells (less uniform cells), low mitotic rate and myocardial infiltration. On immunohistochemical analysis anti-cytokeratin, anti-vimentin and anti-S-100 antibodies were used. Tumour cells stained was absent for anti-cytokeratin and anti-vimentin, but was anti-S-100 positive. A case of malignant aortic body paraganglioma grade II was diagnosed.[…](AU)

Multiple congenital encephalic malformations in a calf

Multiple congenital malformations of the central nervous system are uncommonly described in domestic animals. A 7-days-old, female, Holstein calf was submitted for necropsy with a history of opisthotonus and permanent lateral recumbence. Clinical signs included apathy, abdominal breathing, occasional flexion of the forelimbs, and decreasing of the superficial and deep sensibility in all limbs. Necropsy and histopathology revealed cerebellar hypoplasia, stenosis of the mesencephalic aqueduct, fusion of the rostral and caudal colliculi, secondary hydrocephaly, villous hypertrophy of the choroid plexus and heterotopy of cerebellar cellular components. Immunohistochemical labeling for the antibody anti-BVDV in fragments of brain resulted negative, suggesting that this virus did not participate in the pathogenesis of these malformations.

Aspectos Clínicos, ultrassonográficos e anatomopatológicos da displasia renal em Lhasa Apso com nefropatia juvenil progressiva / Aspects clinical, ultrasonographic and pathologic features of renal dysplasia in Lhasa Apso with progressive juvenile nephropathy

A displasia renal é caracterizada como uma desordem do parênquima renal. Ocorre no período embrionário durante a diferenciação dos tecidos renais e sua etiologia ainda permanece indefinida. Esta patologia, de origem congênita e hereditária, acomete principalmente animais jovens. A afecção pode levar ao desenvolvimento de doença renal crônica, com manifestação clínica de poliúria, polidipsia, perda de peso e apatia. Exames de imagem auxiliam na avaliação da arquitetura renal, evidenciando áreas de perda da definição córtico-medular. O diagnóstico definitivo é obtido por histopatologia. Destaca-se a importância de evitar o cruzamento de animais portadores de displasia renal, pois a doença é de caráter transmissível. O presente trabalho tem por objetivo relatar um caso de displasia renal, em um canino da raça Lhasa-apso, caracterizando seus aspectos clínicos, ultrassonográficos e anatomopatológicos.AU

Renal dysplasia is characterized as a disorder of the renal parenchyma. It occurs in the embryonic period during differentiation of renal tissues and its etiology remains unclear. This congenital and hereditary pathology affects mainly young animals. The condition can lead to the development of chronic kidney disease with clinical signs of polyuria, polydipsia, weight loss and apathy. Imaging tests help the evaluation of renal architecture, highlighting areas of loss of cortical-medular definition. The definitive diagnosis is made by histopathology. Highlights the importance of avoiding crossing animals with renal dysplasia, because the disease is transmitted character. This paper aims to report a case of renal dysplasia in a Lhasa-apso canine, featuring its clinical, ultrasonographic and anatomopathological aspects.AU

Este trabalho teve por objetivo avaliar o perfil microbiológico das refeições comercializadas nos restaurantes do Município de Camaçari-BA, no período de janeiro a dezembro de 2006. Para realização desse estudo foram utilizados 241 laudos produzidos pelo Laboratório Central de Saúde Pública (LACEN) Professor Gonçalo Moniz, credenciado pela Vigilância Sanitária Municipal, referente às análises microbiológicas de alimentos coletadas em 59 restaurantes da cidade de Camaçari-Bahia. Foram pesquisadas Salmonella sp, contagem de B. cereus, contagem de Estafilococos coagulase positiva, contagem de Clostridium sulfito redutores e contagem de Coliformes termotolerantes, de acordo com os métodos preconizados pela American Public Health Association (APHA), utilizando para avaliação os parâmetros referidos na resolução RDC nº12 12001 ANVISA. Das 241 amostras coletadas 61,4% (148) foram consideradas satisfatórias e 38,6% (93) estavam impróprias para o consumo humano. Em 74,6% (44) dos restaurantes ocorreu contaminação em uma ou mais amostras e em 25,4% (15) todas as amostras foram consideradas satisfatórias. Conclui-se que a ocorrência de 35,7% de coliformes termotolerantes indica práticas de higiene inadequadas, a presença de como E. coli e B. cereus em 8,7%, 8,3% respectivamente nas 241 amostras coletadas, aponta um risco considerável de ocorrência de surto de DTA, envolvendo os restaurantes da cidade.(AU)

This work had the objective of evaluate the microbiological profile of the commercialized meals of restaurants of the City of Camaçari-Ba, in the period of January the December of 2006.

Características Morfológicas e Bioquímicas do pólen coletado por cinco espécies de Meliponíneos da Amazônia Central

The pollen grains collected by Melipona seminigra merrillae, Melipona compressipes manaosensis, Melipona seminigra seminigra, Frieseomelitta sp. and Scaptotrigona sp. were obtained directly from the corbiculae of the worker bees during one year. Identification of the pollen grains showed that Scaptotrigona sp. was the most generalist bee, followed by Frieseomelitta sp., which together collected more pollen taxa than the three species of Melipona. Pollen from three plant species: Miconia myrianthera, Myrcia amazonica e Tapirira guianensis -were collected by this five bee species. Regarding pollen morphology, no significant correlations were found that could indicate a preference for certain pollen grain forms, external structures or sizes of grains. All five meliponids collected pollen of several forms and sizes. It is indicative that the bees collected pollen in accordance to protoplasmic nutrients. Biochemical analyses of some pollen types carried on the corbiculae of the bees showed a high concentration of total soluble sugars, reductive sugars and starch.

Durante um ano, o pólen transportado por Melipona compressipes manaosensis, Melipona seminigra merrillae, Melipona seminigra seminigra, Frieseomelitta sp. e Scaptotrigona sp. foi coletado diretamente das corbículas das operárias. Feita a identificação dos grãos de pólen constatou-se que a abelha mais generalista foi Scaptotrigona sp., seguida de Frieseomelitta sp., as quais juntas coletaram mais tipos polínicos que as três espécies de meliponas. Duas espécies de plantas: Miconia myrianthera e Myrcia amazonica, tiveram seu pólen coletado pelas cinco espécies de meliponíneos durante o ano todo. Quanto à morfologia do pólen, não houve correlação significativa que comprovasse que as abelhas coletassem o pólen de acordo com a forma, ornamentação e o tamanho dos grãos. As cinco espécies de meliponíneos coletaram pólen de diversas formas e tamanhos. Tudo indica que as abelhas coletam o pólen de acordo com os nutrientes contidos no seu protoplasma. Análises bioquímicas de alguns tipos polínicos encontrados nas corbículas das abelhas apresentaram alto teor de açúcares solúveis totais, açúcares redutores e amido.
