Correlação dos achados clínicos e hematológicos com diagnóstico definitivo de erliquiose canina por meio de PCR

The Ehrlichiosis is a worldwide diseases of great importance in a veterinary medicine is an important infectious diseases whose prevalence has increased significant in the last year in the Brazilian states. Due to the fact that this study was designed to correlate the findings hematological clinical signs and PCR, being the most sensitive. This study evaluated twenty dogs seen at veterinary hospital UNESP - Botucatu campus during the 03 from august to September 28 2009. Animal cited 65% were positive in the PCR test. Among the most prominent clinical findings 76.92% (10/13) with anorexia, 53.84% (7/13) with hepatoesplenomegaly, 46.15% (6/13) with apathy and 38.46% (5/13) epistaxis. The thirteen animals positive PCR 92.30% (12/13) showed thrombocytopenia (<150.000 platelets) e 61.53 (8/13) anemic (<5.50 x10). Thus, we conclude that the PCR was a good method for detection differential canine ehrlichiosis may be adopted together with the clinical and hematological findings for the accurate diagnosis of the disease.

Expressão gênica dos REα, REβ e PR em tumores mamários de cadelas por meio do q-PCR

A expressão de receptores de estrógeno (ER) e progesterona (PR) por meio da técnica de q-PCR foi avaliada em 26 cadelas portadoras de neoplasias mamárias e cinco cadelas sem afecções mamárias (grupo controle). Os resultados mostraram que os três grupos de animais estudados - com tumor maligno ou benigno e controle - expressaram receptores de estrógeno alfa, beta e progesterona. A quantificação relativa mostrou tendência para uma expressão maior de receptores no grupo controle e menor no grupo de animais com neoplasias malignas. Além disso, observou-se expressão maior de ERα em relação ao ERβ, e as neoplasias malignas de origem mista apresentaram maiores concentrações dos receptores PR, ERα e ERβ que as neoplasias de origem epitelial.

Detection of bovine Herpesvirus type 5 in formalin-fixed, paraffin-embedded bovine brain by PCR: a useful adjunct to conventional tissue-based diagnostic test of bovine encephalitis

The aim of this study was to evaluate the application of PCR technique for the detection of BoHV-5 in routinely formalin-fixed, paraffin-embedded brain tissues in 20 naturally infected calves affected by fatal meningoencephalitis. Brains were divided into two halves, one kept fresh for virus isolation and PCR assay, targeting the glycoprotein C gene from BoHV-5 genome. The other half brain, corresponding to posterior cortex region, was submitted to formalin fixation and embedded into paraffin blocks for microscopic evaluation and total DNA isolation. Most of the slides showed severe multifocal non-supurative encephalitis with neuronal degeneration, neurophagia, and no acidophilic intranuclear inclusions could be found in neurons and glial. The 20 fresh samples were confirmed, by virus isolation and PCR assay, as having the BoHV-5 virus and, respective glicoprotein C sequence, while 15 of 20 formalin-fixed, paraffin-embedded samples were considered positive for the same analysis. The results revealed the first description of PCR efficiency, applied to formalin-fixed, paraffin-embedded brain collected from naturally infected calves, improving the detection of BoHV-5 from archival samples in South America.
