• Abstract

  Avian pathogenic Escherichia coli strains (APEC) are considered to be either primary or secondary infectious agents causing localized or systemic diseases in birds. Although many virulence genes in APEC strains, such as adhesions, secretion systems, iron biding systems, etc., were already described many other genes could play a role in the infectious process of this type of strain. The op…

  Analysis of gene expression and phenotipic characteristics of avian pathogenic Escherichia coli strains(APEC) mutants for lysin descarboxilase operon (LDC-), AP.R

• Abstract

  Escherichia coli strains that cause diseases outside the intestine are known as extra intestinal pathogenic E. coli (ExPEC) which includes human uropathogenic E. coli (UPEC) and avian pathogenic E. coli (APEC). Our group has been working, for several years, in the study of APECs, in order to characterize these types of bacteria strains for their biological characteristics related to patho…

  In vivo analyses of genic expression and mutation in quorum sensing gene AI-2 of an avian Pathogenic Escherichia coli strain, AP.R

• Abstract

  Brazil is the third larger producer and the larger exporter of poultry meat in the world. The production is estimated on over 12 millions of ton. From this amount, almost 4 millions of tons are exported, yielding an income of about US$ 6 billions. Lineages of avian pathogenic Escherichia coli (APEC) are agents of significant degrees of morbidity and mortality for meat poultry and layer he…

• Abstract

  Aquaculture is an economic activity that is soaring in the whole world, including Brazil. In this context, Nile tilapia (Oreochromis niloticus) has showed an increased potential, and has become the most raised species within Brazil. However, the expansion of fish-farming in Brazil is still not well managed. Fish-farming in Brazil presents high rates of deaths, mainly due to bacterial dise…

  Comparison between the gut microbiome of healthy fish and fish experimentally infected with Streptococcus agalactiae, BP.MS

• Abstract

  The Brazil is currently the third largest producer of poultry meat, the largest exporter, which demonstrates the importance of the poultry industry for domestic and foreign economies, creating jobs, high protein foods with low cost and currency. Infections caused by pathogens such as viruses, fungi and bacteria such as Escherichia coli, are agents that, in addition to affecting the poultr…

  Study and molecular characterization of Uropathogenics Escherichia coli strains and its potential as pathogenic strains for poultry (APEC), BP.PD

• Abstract

  Currently, Brazil is the largest exporter of chicken meat and the third largest producer in the world, therefore the poultry industry is important to domestic and export economies. Despite being an important economic sector, the poultry industry is subject to factors that could significantly affect its revenues and costs. Among them, the infections caused by avian pathogenic Escherichia c…

  Site-directed mutagenesis of a new autotransporter in an avian pathogenic Escherichia coli strain (APEC) and evaluation of the contribution of this gene to pathogenesis, BP.PD

• Abstract

  Linhagens de Escherichia coli patogênica para aves (APEC) são agentes relacionados a graus significantes de morbidade e mortalidade em frangos de corte a aves poedeiras, causando prejuízo na indústria aviária no mundo todo. Além disso, tem sido sugerido que linhagens APEC podem apresentar um papel como agentes zoonóticos. Neste projeto, nosso objetivo é montar os genomas de linhagens APEC…
