1. Parenteral adjuvant potential of recombinant B subunit of Escherichia coli heat-labile enterotoxin
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin (LTB) is a potent mucosal immune adjuvant. However, there is little information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a parenteral adjuvant using the fused R1 repeat of Mycoplasma hyopneumoniae P97 ad

2. Phenotypical characterization and adhesin identification in Escherichia coli strains isolated from dogs with urinary tract infections
Pathogenic strains of Escherichia coli are the most common bacteria associated with urinary tract infections in both humans and companion animals. Standard biochemical tests may be useful in demonstrating detailed phenotypical characteristics of these strains. Thirteen strains of E. coli isolated from dogs with UTIs were submitted to biochemical tests, serot

3. Validation and utilization of PCR for differential diagnosis and prevalence determination of Entamoeba histolytica/Entamoeba dispar in Salvador City, Brazil
Amoebiasis is an infection caused by Entamoeba histolytica and is a potential health risk in countries in which health barriers are inappropriate. Since the discovery of Entamoeba dispar, the prevalence of amoebiasis has been modified. OBJECTIVE: This study has standardized the PCR technique applied for the diagnosis of different species of the E. histolytic

4. Helicobacter pylori adhesion to gastric epithelial cells is mediated by glycan receptors
Helicobacter pylori adhesion to gastric epithelial cells constitutes a key step in the establishment of a successful infection of the gastric mucosa. The high representation of outer membrane proteins in the bacterial genome suggests the relevance of those proteins in the establishment of profitable interactions with the host gastric cells. Gastric epithelia

5. Formação de biofilme em amostras de Escherichia coli associada a sepse (SEPEC) : caracterização fenotipica, genotipica e filogenia / Biofilm formation by sepsis associated Escherichia coli (SEPEC) strains : genotypic, phenotypic characterization and phylogeny
Extraintestinal Pathogenic Escherichia coli (ExPEC) form a heterogeneous group as the bacterial virulence factors involved in its pathogenicity and local infection in the host. Our work aimed study the phenotypic and genotypic characteristics of biofilm formation and phylogeny of sepsis-associated Escherichia coli Human (SEPEC), as well as their patterns of

8. Serogroups and virulence genotypes of Escherichia coli isolated from patients with sepsis
Sixty strains of Escherichia coli, isolated by hemoculture, from septicemic Brazilian patients were evaluated to determine their serogroup and invasivity to Vero cells. All 60 patients died within 2 days of hospitalization. Furthermore, the molecular study of the following extraintestinal pathogenic E. coli-associated virulence factor (VF) genes was performe

9. Mecanismos de patogenia do Mycobacterium leprae: Análise de proteínas extracelulares e efeitos sobre o metabolismo lipídico do hospedeiro. / Mechanisms of Mycobacterium leprae pathogenesis: Analysis of the extracellular proteins and effect on the host lipid metabolism.
The complete sequence of the Mycobacterium leprae genome, together with recent advances in the definition of its proteome, are contributing to our understanding of leprosy pathogenesis, so far a difficult task due to the unique properties of this bacterium. The major goal of the present study was to identify and functionally characterize extracellular M. lep

10. Anaplasma marginale : análise da variabilidade do gene msp1 a e avaliação imunogênica da vacina de DNA contendo genes para MSP1a, MSP1b e MSP5 em camundongos BALB/c
Anaplasma marginale is an important tick-transmitted rickettsial pathogen of cattle that invades and multiplies within erythrocytes, causing severe hemolytic anemia during acute infection. Immunization with purified outer membrane proteins (OMP) induces protection against acute A. marginale disease. Of 21 OMP described six major surface proteins (MSPs 1a, 1b

11. Biologicals and moleculars methods in the study of virulence factors in Eschericia coli strains isolated by blood culture of patients with septicaemia / Metodos biologicos e moleculares no estudo de fatores de virulencia em amostras de Eschericia coli isoladas por hemocultura de pacientes com septicemia
The pathogenicity of Escherichia coli in extraintestinal infections (ExPEC) depends to virulence properties bacterial. This, genetically, spread by several pathogenicity associated islands ? genic blocks contiguous ? responsible to express factors that allow to bacteria colonize, survive and thus, hurt the host integrity. Seventh tree strains of E. coli isol

12. Análise microbiológica de pontas de cateteres venosos centrais de pacientes do Hospital Universitário - Londrina - Paraná
Cateteres venosos centrais (CVC) são utilizados com a finalidade de facilitar o diagnóstico e o tratamento de pacientes hospitalizados. Entretanto, o uso destes oferece riscos de infecção local e sistêmica. Staphylococcus aureus e S. epidermidis são agentes etiológicos de infecções relacionadas a CVC e possuem a capacidade de produzir biofilme. A fo
