Bacteria can change its lifestyle during inhabiting in host niches where they survive and replicate by rapidly altering gene expression pattern to accommodate the new environment. In this study, two novel regulators in avian pathogenic Escherichia coli (APEC) were identified and designated as AutA and AutR. RT-PCR and β-galactosidase assay results showed that AutA and AutR co-regulated the expr...

The measurement of impediments to trade in services within the APEC region is addressed in this paper. This work builds upon major methodological and practical issues encountered in measuring such impediments in the 1995 PECC Survey of Impediments to Trade and Investment in the APEC Region. Conceptual and measurement issues in deriving partial equilibrium estimates of the effects of service tra...

Infections caused by avian pathogenic Escherichia coli (APEC) cause important economic losses to poultry industry. The studies presented herein, aimed at investigating the in vivo performance of a cocktail of three phages in treating severe respiratory E. coli infections in experimentally contaminated birds and naturally infected flocks. Three lytic coliphages, phi F78E (Myoviridae), phi F258E ...

Avian pathogenic Escherichia coli (APEC) leads to economic losses in poultry production and is also a threat to human health. The goal of this study was to characterize the chicken spleen transcriptome and to identify candidate genes for response and resistance to APEC infection using Solexa sequencing. We obtained 14422935, 14104324, and 14954692 Solexa read pairs for non-challenged (NC), chal...

Fingerprints-based methods have been prevailing in indoor positioning systems, whereas they have certain drawbacks that fingerprints collection in the offline phase requires considerable manpower and time. Auto Planner for Efficient Configuration (APEC) systematically exploits router setups and fingerprints allocations over space by taking into account user preferences and budget constraints. T...

Avian pathogenic Escherichia coli (APEC) is an important respiratory pathogen of poultry. Various virulence factors are responsible for determining the pathogenicity of these strains, and it is commonly believed they are encoded on large plasmids the strains carry. This study examined a series of strains, the pathogenicity of which had previously been determined by aerosol exposure, for possess...

چکیده فارسی کلی باسیلوز پرندگان توسط اشریشیاکلی بیماریزای پرندگان (apec) ایجاد می گردد. علی رغم اینکه بیش از یک قرن است که apec شناخته شده است، کلی باسیلوز پرندگان به عنوان یک بیماری مهم آندمیک که صنعت طیور دنیا را با مشکل مواجه کرده مطرح است. اشریشیا کلی بیماریزای پرندگان موجب التهاب کیسه های هوایی، سپتی سمی و عموماً دیگر بیماری های خارج روده ای در ماکیان، بوقلمون و دیگر گونه های پرندگان می ش...

Background: Avian pathogenic Escherichia coli (APEC), which is the causative agent of colibacillosis, harbors several putative virulence genes. An important trait of APEC for both poultry and public health is antibiotic resistance. Objectives: In the present study, some potential virulence genes of APECs isolated from Northeast of Iran and their resistance to the quinolones antibiotics were stu...

Background: Avian pathogenic Escherichia coli (APEC) strains have been associated with various disease conditions in avian species due to virulence attributes associated with the organism. Aims: This study was carried out to determine the in vitro pathogenic characteristics and virulence encoding genes found in E. coli strains associated with colibacillosis in chickens. Methods: Fifty-two stock...
