Abstract

Potlatch é o título do boletim de informação da Internacional Letrista, que circulou, a partir de Paris, seu centro de produção, entre 1954 e 1957. A I.L., tendo se formado enquanto ruptura de uma vanguarda artística (o letrismo de Isidore Isou), propõe em seu pequeno veículo práticas, formulações teóricas e críticas que darão mais tarde base à organização da Internacional Situacionista. Este artigo faz a análise deste material, buscando compreender a originalidade de seu posicionamento crítico em relação à arte, ao espaço urbano e a vida cotidiana, bem como do conteúdo político de suas ações e experimentações, direcionadas, antes de tudo, a explorar as possibilidades de superação das relações sociais de produção capitalistas.

Abstract

Sampling protocols for detecting Salmonella on poultry differ among various countries. In the United States, the U.S. Department of Agriculture Food Safety and Inspection Service dictates that whole broiler carcasses should be rinsed with 400 ml of 1% buffered peptone water, whereas in the European Union 25-g samples composed of neck skin from three carcasses are evaluated. The purpose of this study was to evaluate a whole carcass rinse (WCR) and a neck skin excision (NS) procedure for Salmonella and Escherichia coli isolation from the same broiler carcass. Carcasses were obtained from three broiler processing plants. The skin around the neck area was aseptically removed and bagged separately from the carcass, and microbiological analysis was performed. The corresponding carcass was bagged and a WCR sample was evaluated. No significant difference (alpha

Abstract

In this study, Lactococcus lactis was engineered to express mutated internalin A on its surface and to secrete large amounts of listeriolysin O (LLO) in order to improve its potential as a vehicle for DNA vaccination. Western blotting experiments demonstrated that the bacterium expressed LLO in both the cytoplasmic and extracellular compartments, with higher quantities found in the culture supernatants. A hemolytic assay showed that the recombinant strain secreted 250 ng active LLO/mg total protein. This mInlA/LLO-producing strain of L. lactis may be used as an alternative tool in DNA vaccination against a number of infectious diseases or in cancer therapy. Fil: de Azevedo, M. S. P..
