Análise fenotípica e molecular da produção de biofilmes por estirpes de staphylococcus aureus isoladas de casos de mastite subclínica bovina

Biofilm formation is considered an advantage for Staphylococcus aureus mastitis isolates, facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers and enclosing in a polymeric matrix known as exopolysaccharide. The objective of this study was to evaluate the ability of Staphylococcus aureus isolated from bovine subclinical mastitis for formation of biofilms. A total of 94 Staphylococcus aureus strains obtained from milk samples of cows suffering from subclinical mastitis in dairy herds on two properties in the state of São Paulo were evaluated. These strains were characterized by in vitro biofilm formation, and by the presence of icaA and icaD genes which are responsible for intercellular adhesion. The results revealed that 98.9% of the isolates produced biofilm in vitro by adherence in sterile 96-well "U" bottom polystyrene tissue culture plates; 95.7% of the isolates possessed the icaA and icaD genes. These bacterial isolates biofilm producers may impair eradication of chronic mastitis, rendering antibiotherapy less effective. The detection of biofilm forming ability in mastitis isolates may provide useful information for more adequate therapeutic regimen and for preventive actions in the control of those bacterial isolates in bovine herds.

Mudança de concepção das políticas públicas para o campo brasileiro: o Programa de Aquisição de Alimentos, PAA

In the 90, the public politics for the Brazilian rural way incorporated the territorial perspective, besides they motivate the participation and the beneficiaries collective organization. In 2003 the Food Acquisition Program (FAP) was created with the intention of guaranteeing the feeding of people in social vulnerability situation or alimentary insecurity and of providing work and income in the field through the direct buying of the agriculturists foods. In a research made in two São Paulo State's towns: Tupi Paulista and Dracena, it was verified that the price paid to the farmers is higher to the regional average and because of this fact the participants have interest in enlarging the cultivated area and/or in diversifying the cultivations. Though, two problems were detected: 1) the reduced number of beneficiated producers; and, ii) the furtherance of the producers relatives already registered that try to increase their quota of products and the value to be received.

Saúde da Família: O desafio de uma atenção coletiva

The Family Health Strategies, incorporated by the Ministry of Health in 1994, has consolidated the national policy of health care that has as its main care focus the family. In this model, this institution constitutes the first object of attention, understood from its environment and interaction. In recent decades, the Brazilian family structure is suffering profound changes that directly affect the practices of health care. This study redeem the family concepts and ideas and their social representations and still prove and present the importance and the necessity of the use of these ample instruments of collective boarding in health area: the APGAR, the genogram and eco-map, using the environment observation and family history - crucial factors to the reality of the nuclear family diagnosis - for further planning of health action strategies. It was concluded that the current structure of the family require training from the health teams, for physical, cultural, biological and social points of the family context for the correct use of the instruments cited, important tools for collective approach in the public health area.
