13. Comparative proteomic analysis of pathogenic and non-pathogenic strains from the swine pathogen Mycoplasma hyopneumoniae
Background: Mycoplasma hyopneumoniae is a highly infectious swine pathogen and is the causative agent of enzootic pneumonia (EP). Following the previous report of a proteomic survey of the pathogenic 7448 strain of swine pathogen, Mycoplasma hyopneumoniae, we performed comparative protein profiling of three M. hyopneumoniae strains, namely the non-pathogenic

14. 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

15. Production and characterization of monoclonal antibodies against the identical region of LigA and LigB proteins from Leptospira interrogans / Produção e caracterização de anticorpos monoclonais contra a região idêntica das proteínas LigA e LigB de Leptospira interrogans
Leptospirosis is a zoonotic disease caused by pathogenic bacteria belonging to the Leptospira genus. Several mammals may carry the agent, and rats are the most important source of human infection in urban settings. The wide spectrum of clinical manifestations varies from mild cases, with fever and headaches, to severe presentations, with liver and kidney fai

16. Avaliação in vitro dos efeitos da nicotina e cotinina sobre a expressão de proteinas e capacidade de adesão e invasão de Porphyromonas gingivalis / In vitro evaluation of nicotine and cotinine effects on protein expression and adhesion and invasion abilities of Porphyromonas gingivalis
Cigarette smoking is associated with the development of periodontitis and the decreased response to periodontal therapy. P. gingivalis is an important colonizer of the subgingival biofilm and is one of the major pathogens involved in the initiation and progression of periodontal disease. However, the possible effects of major cigarette s derivatives on P. gi

17. 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

18. Estudo microbiológico fecal de linhagens de camundongos, de estirpes de E. coli e do meio ambiente em biotérios / Fecal microbiologic study of mice lineages, E. coli strains and the environment in laboratory animal facilities
Mice have been largely used at experiences since 17o century, so their microbiological quality should be investigated and kept safety in order to avoid they become ill or die during an investigation and dont transmit zoonosis to those who handle them; this is important in order to make the results presented in the experience be reliable. The Escherichia coli

19. 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

20. Expression, purification and characterization of adhesins involved in biofilm formation Xylella fastidiosa / Expressão, caracterização e purificação de adesinas envolvidas na formação do biofilme de Xylella fastidiosa
É inquestionável a importância da participação da citricultura na economia brasileira. O Brasil é o maior exportador de suco concentrado do mundo. Em 2007 as exportações brasileiras quase alcançaram 400 milhões de caixas de laranja, retrato de uma cultura que gera uma diversidade enorme de empregos diretos e indiretos, movimentando também a indús

21. Association of IL-8-inducing strains of diffusely adherent Escherichia coli with sporadic diarrheal patients with less than 5 years of age
The role of diffusely adherent Escherichia coli (DAEC) in diarrheal disease has been controversial. However, DAEC strains were recently implicated in diarrheal disease in developing countries. To clarify whether DAEC are prevalent among sporadic cases of diarrheal illness in Osaka City, Japan, E. coli strains isolated between July 1997 and March 2000 during

22. Análise global da expressão gênica de Xylella fastidiosa submetida a estresses ambientais / Global gene expression analysis of Xylella fastidiosa under environmental stress conditions
Xylella fastidiosa is a phytopathogenic bacterium responsible for diseases in many economically important crops. Although different strains have been studied, little is known about X. fastidiosa stress responses. To investigate X. fastidiosa genes involved in heat, salt and osmotic shock responses, we performed a whole genome microarray analysis in time-cour

23. 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

24. Caracterização de um novo fator de colonização (FC O25) de Escherichia coli isoladas de colibacilose neonatal bovina / Characterization of a new colonization (CF O25) of Escherichia coli isolated from neonatal bovine colibacillosis
Infections from Escherichia coli are frequent in domestic animals, affecting mainly newborn animals in the post weaning period, being thus responsible for important economic losses in the cattle, porcine and lamb herds. The establishment of the bacterium in the host is made by colonization and it is a process mediated by proteins called adhesins that are dis
