1. Validity of periodontitis screening questions in a Brazilian adult population-based study
Abstract Population-based studies assessing self-reported periodontal questions in low-income countries are lacking, and therefore we aimed to assess the accuracy of self-reported periodontal items in Brazil. One thousand one hundred and forty adults from Florianópolis, Brazil, had their periodontium clinically examined, and responded to the following self-

2. A CssA, CssB and LTB chimeric protein induces protection against Enterotoxigenic Escherichia coli
OBJECTIVES: Enterotoxigenic Escherichia coli (ETEC), a major cause of diarrhea in children under 5, is an important agent for traveler's diarrhea. Heat-labile enterotoxin (LT) and colonization factors (CFs) are two main virulence mechanisms in ETEC. CS6 is one of the most prevalent CFs consisting of two structural subunits viz., CssA, CssB, necessary for a

3. Comparison of methods for the detection of biofilm formation by Staphylococcus aureus isolated from bovine subclinical mastitis
Biofilm formation is considered to be a selective advantage for Staphylococcus aureus mastitis isolates by facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers. The objective of this study was to determine the sensitivity and specificity of three techniques for t

4. The ability of the BANA test to detect different levels of P. gingivalis, T. denticola and T. forsythia
The aim of this study was to evaluate the ability of the BANA Test to detect different levels of Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia or their combinations in subgingival samples at the initial diagnosis and after periodontal therapy. Periodontal sites with probing depths between 5-7 mm and clinical attachment level between

5. As especificidades do padrão de apego da criança em relação à figura materna e paterna
Esta dissertação apresenta uma pesquisa qualitativa que investigou a especificidade do padrão de apego de crianças na relação com seus cuidadores principais, em especial mãe e pai. O referencial teórico de base foi a teoria do apego, desde os conceitos iniciais de Bowlby até as novas perspectivas conceituais, sustentadas pelos pesquisadores que segu

6. Comparação entre teste bana e checkerboard dna-dna hybridization no diagnóstico periodontal inicial e no monitoramento terapêutico
The aim of this study was tom compare the results of the BANA with the presence of the red complex microorganisms established by the Checkerboard DNA-DNA hybridization in the initial diagnosis and in the therapeutic maintenance of subjects with periodontitis. 54 subjects with chronic periodontitis with at least 15 teeth were selected. Subgingival plaque samp

7. Specificity determinants in the attachment sites of bacteriophages HK022 and lambda.
The Int proteins of bacteriophages HK022 and lambda promote recombination between phage and bacterial attachment sites. Although the proteins and attachment sites of the two phages are similar, neither protein promotes efficient recombination between the pair of attachment sites used by the other phage. To analyze this difference in specificity, we construct

8. Altered receptor specificity of coxsackievirus B3 after growth in rhabdomyosarcoma cells.
Serial "blind" passages in human rhabdomyosarcoma (RD) cells of prototype viruses from each of the six immunotypes of the group B coxsackieviruses (CB) resulted in the isolation of intratypic variants of CB1, CB3, CB5, and CB6. Each variant virus strain acquired the capacity to agglutinate human erythrocytes and produce small plaques on HeLa cells, although

10. Respiratory Syncytial Virus (RSV) Fusion Protein Subunit F2, Not Attachment Protein G, Determines the Specificity of RSV Infection
Human respiratory syncytial virus (HRSV) and bovine RSV (BRSV) infect human beings and cattle in a species-specific manner. We have here analyzed the contribution of RSV envelope proteins to species-specific entry into cells. In contrast to permanent cell lines, primary cells of human or bovine origin, including differentiated respiratory epithelia, peripher

11. Species specificity of Bordetella adherence to human and animal ciliated respiratory epithelial cells.
Bacteria of the genus Bordetella adhere preferentially to ciliated respiratory epithelial cells. We investigated the specificity of this unique tropism by assessing the concentration-dependent adherence of the three Bordetella species to ciliated cells from different hosts. Bordetella pertussis and Bordetella parapertussis adhere better to human ciliated cel
