Twelve dogs from urban areas were studied by blood smear examination and the poly- merase chain reaction (PCR) assay. From these dogs, only 1 was positive in both blood smears and PCR.

Os pinguins-de-Magalhães são aves marinhas migratórias que passam pela plataforma continental brasileira e podem se perder atingindo as praias do Rio de Janeiro. As aves resgatadas se apresentam enfraquecidas e susceptíveis a infec-ções oportunistas. Edwardsiella tarda, bactéria da família Enterobacteriaceae, constitui espécie pato-gênica podendo causar distúrbios intestinais e ex-tra intestinais. A fauna marinha é considerada seu reservatório. Assim, objetivou-se relatar um caso Almosny N.R.P. tarda in Sphe-niscus magellanicus de Edwardsiella tarda em processo septicêmico em Spheniscus magellanicus (Sphenis-ciformes: Spheniscidae) -Relato de caso. Revista Brasileira de Medicina Veterinária, 35(3):224-228, 2013. The Magellanic penguins are seabirds that migrate through the Brazilian continental shelf and may be lost reaching the beaches of Rio de Janeiro. The rescued birds became weakened and susceptible to opportunistic ...

Aiming to validate the morphological diagnosis for A platys, 101 dogs were selected due to the appearance of inclusion bodies, indepen- dently from suggestive parasites, which were submitted to polymerase chain reac- tion (PCR) carried out in 2 stages. The first stage consisted of the utilization of initialing sequences or specific primers for the detec- tion of some species of the Anaplasmataceae family, such as: Ehrlichia canis, Ehrlichia chaffeensis, Ehrlichia muris, Ehrlichia ruminantium, Anaplasma phagocytophilum, A platys, Anaplasma marginale, Anaplasma centrale, Wolbachia pipientis, Neorickettsia sennetsu, Neorickettsia risticii, and Neor- ickettsia helminthoeca (PCR1). The second stage consisted of the utilization of specific primers for the detection of the spe...

Among the existent diagnostic methods, the most used include: morulae identification in blood smears; antibody detection by indirect immunofluorescence; or DNA amplification by polymerase chain reaction (PCR). Recently a new commercial ELISA (IDEXX®), capable of detecting A. phagocytophilum antibodies, has been developed. According to the manufacturer it appears to have a serological cross reaction with A. platys which may be used to help in the diagnosis of this agent. The aim of this study was to test serum samples from 16 PCR-positive dogs to A. platys with an ELISA that detects antibodies to A. phagocytophilum, Borrelia burgdorferi and Ehrlichia canis, and antigens of Dirofilaria immitis in order to verify the occurrence of cross reaction between A. platys and A. phagocytophilum. All animals tested negative for A. phagocytophil...

Para isto, foram apresentados os fundamentos históricos e conceituais do movimento e ainda foi adotada a perspectiva teórica do consumo sustentável para nortear empiricamente o estudo. Em termos metodológicos, foram adotadas duas abordagens de cunho qualitativo, sendo a primeira coleta de dados orientada por um roteiro de entrevistas semiestruturado e a segunda coleta de dados realizada por meio da coleta de posts no grupo do Facebook “Projeto Beleza Minimalista”. Os resultados identificaram aspectos como perspectivas de mercado, estilo de vida, hábitos de consumo, nível de conhecimento, percepções de atributos dos produtos naturais, orgânicos e veganos e o consumo enquanto processo cultural, além de incorporar novos elementos para compreensão do consumo consciente
