1. Detection of virulence genes in Salmonella Heidelberg isolated from chicken carcasses
ABSTRACT During the last years, Brazilian government control programs have detected an increase of Salmonella Heidelberg in poultry slaughterhouses a condition that poses a threat to human health However, the reasons remain unclear. Differences in genetic virulence profiles may be a possible justification. In addition, effective control of Salmonella is rela

2. Virulence potential and antibiotic susceptibility pattern of motile aeromonads associated with freshwater ornamental fish culture systems: a possible threat to public health
Aeromonas spp. are ubiquitous aquatic organisms, associated with multitude of diseases in several species of animals, including fishes and humans. In the present study, water samples from two ornamental fish culture systems were analyzed for the presence of Aeromonas. Nutrient agar was used for Aeromonas isolation, and colonies (60 No) were identified throug

3. Desinfestação de substratos e fungos micorrízicos na produção de porta-enxertos de citros / Substrates and mycorrhizal fungi in the production of citrus rootstocks
The Brazilian citrus industry is one of the most competitive sectors of the agribusiness world, however, the production sector of citrus seedlings has several limitations. The citrus production rootstocks lacks quality of substrates, options for diversification of rootstock varieties and plants well-formed in a short time to reach success of the orchard. The

4. CaracterizaÃÃo fenotÃpica e genotÃpica, sensibilidade a antimicrobianos e detecÃÃo de gene de virulÃncia de cepas clÃnicas e ambientais de Burkholderia pseudomallei. / Genotyping, antimicrobial susceptibility and detection of virulence genes of clinical and environmental strains of Burkholderia pseudomallei isolated in Ceara.
Melioidosis is a serious infectious disease caused by Burkholderia pseudomallei, a Gram negative rod, commonly found in soil and water. The disease is endemic in Southeastern Asia and hyperendemic in Northern Australia. Despite the initiation of empiric therapy, mortality remains at 21% in patients with melioidosis in Australia. In Brazil, it is considered a

5. Caracterização dos fatores sigma da RNA polimerase do fitopatógeno Xanthononas axonopodis pv. citri / Caracterization of RNA polimerase sigma factor of phythopathogen Xanthomonas axonopodis pv. citri.
A citricultura é de grande importância para as atividades agrícolas brasileiras, uma vez que o Brasil é o principal produtor e exportador de suco de laranja. O cancro cítrico, causado pela bactéria Xanthomonas axonopodis pv. citri (Xac) é um grave problema nesse setor, causando um elevado prejuízo na produção de frutos e seus derivados. O fator sig

6. Caracterização molecular da interação entre proteínas de citros envolvidas no controle da expressão gênica e a proteína efetora bacteriana PthA, indutorra do cancro cítrico / Molecular characterization of the interaction between citrus proteins involved in gene transcription control and the effector protein PthA, a citrus canker disease inductor
O cancro cítrico, causado pela bactéria Xanthomonas axonopodis pv. citri (Xac), é uma doença que afeta a maioria das espécies do gênero Citrus, ocorrendo praticamente em todos os continentes, e se destaca como uma das ameaças à citricultura brasileira. O mecanismo molecular pelo qual Xac causa o cancro não é inteiramente conhecido, entretanto, sabe

8. Caracterização de prováveis genes do sistema de secreção tipo III em Escherichia coli de adesão difusa
The diffusely adhering Escherichia coli (DAEC) is a heterogeneous group and less characterized when compared to other pathotypes of E. coli. The fact that some strains are pathogenic and others not, creates doubts about the exact classification of this group. Contributes to it, the lack of molecular markers corresponding to the virulence genes of DAEC. Some

10. Functional Characterization of Two Type III Secretion Systems of Vibrio parahaemolyticus
Vibrio parahaemolyticus, a gram-negative marine bacterium, is a worldwide cause of food-borne gastroenteritis. Recent genome sequencing of the clinical V. parahaemolyticus strain RIMD2210633 identified two sets of genes for the type III secretion system (TTSS), TTSS1 and TTSS2. Here, we constructed a series of mutant strains from RIMD2210633 to determine whe

11. A conserved amino acid sequence directing intracellular type III secretion by Salmonella typhimurium
Type III secretion systems (TTSS) are important virulence factors that Gram-negative bacteria use to translocate proteins into the cytoplasm of eukaryotic host cells. Salmonellae encode two virulence-associated TTSS. The Salmonella pathogenicity island 1 (SPI1)-encoded TTSS is active on contact with host cells, whereas the Salmonella pathogenicity island 2 (

12. Process of Protein Transport by the Type III Secretion System
The type III secretion system (TTSS) of gram-negative bacteria is responsible for delivering bacterial proteins, termed effectors, from the bacterial cytosol directly into the interior of host cells. The TTSS is expressed predominantly by pathogenic bacteria and is usually used to introduce deleterious effectors into host cells. While biochemical activities
