26. 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

27. Clinical, genetic and molecular study of Rokitansky-Mayer-Küster-Hauser syndrome and related conditions / Estudo genético-clínico e molecular da síndrome de Rokitansky-Mayer-Küster-Hauser e condições afins
Background: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, comprising utero-vaginal atresia in otherwise phenotypically normal women with a normal karyotype (46,XX), has an incidence of about 1/5,000 among newborn girls. Anomalies of the genital tract range from upper vaginal atresia to total Müllerian agenesis (congenital absence of the Fallopian tubes,

28. GINGA - Graphical Interface for Comparative Genome Analysis: o desenvolvimento de um sistema computacional de visualização gráfica para a análise comparativa de genomas de bactérias / GINGA - Graphical Interface for comparative Genome Analysis: development of a computational system to visualize the comparative of bacterial genomes in a graphical view
This study aimed to develop a computational system applied to the comparative analysis of prokaryotic genomes in a graphical view. The system named GINGA Graphical Interface for comparative Genome Analysis was developed to analyse a draft genome sequence in comparison to a complete genome. The system shows the alignment between sequence of reads, contigs and

29. Genes involved in cell division in mycoplasmas
Bacterial cell division has been studied mainly in model systems such as Escherichia coli and Bacillus subtilis, where it is described as a complex process with the participation of a group of proteins which assemble into a multiprotein complex called the septal ring. Mycoplasmas are cell wall-less bacteria presenting a reduced genome. Thus, it was important

30. Implicação de genes da zona de plasticidade e da ilha de patogenicidade cag (PAIcag) de Helicobacter pylori no desenvolvimento de doenças gastroduodenais / Implication of Helicobacter pulori plasticity region and cag pathogenicity island (cagPAI) genes on the development of gastroduodenal diseases
Helicobacter pylori is a Gram-negative, spiral-shaped, flagellated, micro-aerophilic bacterium, included in the Helicobacteraceae family, which infects the human stomach cronically. H. pylori infection has a worldwide distribution and is associated with the development of several gastroduodenal diseases, such as gastritis, peptic ulcer disease (PUD) and its

31. A bacterial artificial chromosome library for Biomphalaria glabrata, intermediate snail host of Schistosoma mansoni
To provide a novel resource for analysis of the genome of Biomphalaria glabrata, members of the international Biomphalaria glabrata Genome Initiative (biology.unm.edu/biomphalaria-genome.html), working with the Arizona Genomics Institute (AGI) and supported by the National Human Genome Research In

32. Gene Expression in Xanthomonas axonopodis pv. citri Mediated by Plant Inducible Promoter (PIP-box) / "Expressão gênica em Xanthomonas axonopodis pv. citri controlada por promotores induzidos pela planta hospedeira"
The citrus canker, caused by the bacterial pathogen Xanthomonas axonopodis pv citri (Xac), is considered worldwide as one of the most important disease of citrus crop due to the lack of resistance in citrus plants and to the absence of efficient methods to control the disease. It was already shown that several genes involved in virulence and pathogenicity in

33. Specific amplification of iron receptor genes in Xylella fastidiosa strains from different hosts
Bacterial production of siderophores may involve specific genes related to nonribosomal peptide and polyketide biosynthesis, which have not been fully identified in the genome of Xylella fastidiosa strain 9a5c. However, a search for siderophore-related genes in strain 9a5c indicated five membrane receptors, including siderophore, ferrichrome-iron and hemin r

34. Expressão em Escherichia coli de Quitinase (E.C. 3.2.1.14) de Chromobacterium violaceum
The sequencing of the Chromobacterium violaceum genome generated the necessity of characterizes the genetic function of the transcripts present in this bacterial chromosome set. In this genome were found several ORFs (Open Read Frame) corresponding to the biotechnological target genes, and among them five that codify Chitinases. This work shows the results o

35. In silico identification of potential chaperone genes that belong to type III and type IV secretion systems in Xanthomonas axonopodis pv citri
The secretion of bacterial virulence factors and flagellar components requires the assistance of specific type III and flagellar chaperones. Standard computational annotation of the genome of Xanthomonas axonopodis pv citri, a plant pathogen that causes citrus canker, initially did not identify any genes belonging to these chaperone categories since the prim

36. Role of the Xf-0818 cellulase in the Xylella fastidiosa X citrus interaction. / Papel da celulase XF-0818 na interação Xylella fastidiosa X Citros.
From the genome sequencing of the bacteria Xylella fastidiosa, the agent responsible for the citrus variegated chlorosis (CVC), studies on the pathogenicity mechanisms expressed during the occurrence of the disease were started in genomic function projects, aiming to confirm the function of the genic sequences identified in the project X. fastidiosa Genome.
