13. A preliminary survey of M. hyopneumoniae virulence factors based on comparative genomic analysis
Mycoplasma hyopneumoniae is the etiological agent of porcine enzootic pneumonia (PEP), a major problem for the pig industry. The mechanisms of M. hyopneumoniae pathogenicity allow to predict the existence of several classes of virulence factors, whose study has been essentially restricted to the characterization of adhesion-related and major antigenic protei

16. 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

17. 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

18. 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

19. 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

20. 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

21. DeterminaÃÃo da PrevalÃncia e Variabilidade GenÃtica de Entamoeba histolytica e Entamoeba dispar em Habitantes de Pernambuco
Previous studies using methods varying from traditional serological test to molecular biology have shown that in Northeast Brazil Entamoeba dispar was more prevalent than Entamoeba histolytica. In this work the prevalence was established by using E. histolytica stool antigen detection kits and Reaction Chain Polimerase (PCR) of genomic DNA extracted from cul

22. Further biochemical characterization of Mycobacterium leprae laminin-binding proteins
It has been demonstrated that the alpha2 chain of laminin-2 present on the surface of Schwann cells is involved in the process of attachment of Mycobacterium leprae to these cells. Searching for M. leprae laminin-binding molecules, in a previous study we isolated and characterized the cationic proteins histone-like protein (Hlp) and ribosomal proteins S4 and

23. Prevalence of Known P-Fimbrial G Alleles in Escherichia coli and Identification of a New Adhesin Class
Screening a large Escherichia coli collection for P-fimbrial adhesin classes identified 20 unclassifiable strains. Cloning and sequencing of papG from an unclassifiable strain identified another G allele. The novel adhesin gene has 65% identity to the class I adhesin gene, 44% identity to the class II adhesin gene, and 43% identity to the class III adhesin g

24. Isolation and characterization of the alpha-sialyl-beta-2,3-galactosyl-specific adhesin from fimbriated Escherichia coli.
The alpha-sialyl-beta-2,3-galactosyl-specific adhesin (S adhesin) was isolated from cells of a recombinant Escherichia coli K-12 strain expressing the S-fimbrial adhesin complex. A crude cell extract was partially dissociated into fimbriae and an adhesin-enriched fraction by heating to 70 degrees C. From the latter, adhesin was purified to apparent homogenei
