BACKGROUND Ileal lesions of Crohn's disease (CD) patients are abnormally colonized by pathogenic adherent-invasive Escherichia coli (AIEC) able to invade and to replicate within intestinal epithelial cells and macrophages. PRINCIPAL FINDINGS We report here the complete genome sequence of E. coli LF82, the reference strain of adherent-invasive E. coli associated with ileal Crohn's disease. The...
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...
A series of strict emission control measures were implemented in Beijing and surrounding regions to ensure good air quality during the 2014 Asia-Pacific Economic Cooperation (APEC) summit and 2015 Grand Military Parade (Parade), which led to blue sky days during these two events commonly referred to as "APEC Blue" and "Parade Blue". Here we calculated Multi-Axis Differential Optical Absorption ...
Avian pathogenic Escherichia coli (APEC), an extraintestinal pathogenic E. coli causing colibacillosis in birds, is responsible for significant economic losses for the poultry industry. Recently, we reported that the APEC pathotype was characterized by possession of a set of genes contained within a 94-kb cluster linked to a ColV plasmid, pAPEC-O2-ColV. These included sitABCD, genes of the aero...
Extraintestinal pathogenic Escherichia coli (ExPEC) has major negative impacts on human and animal health. Recent research suggests food-borne links between human and animal ExPEC diseases with particular concern for poultry contaminated with avian pathogenic E. coli (APEC), the avian ExPEC. APEC is also a very important animal pathogen, causing colibacillosis, one of the world's most widesprea...
Extra-intestinal pathogenic Escherichia coli (ExPEC) represent an emerging pathogen, with pandemic strains increasingly involved in cases of urinary tract infections (UTIs), bacteremia, and meningitis. In addition to affecting humans, the avian pathotype of ExPEC, avian pathogenic E. coli (APEC), causes severe economic losses to the poultry industry. Several studies have revealed overlapping ch...
Asia Pacific Economic Cooperation (APEC) forum launched a process that could ultimately produce the largest single act of trade liberalization in history. They agreed to " seriously consider " negotiating a Free Trade Area of the Asia Pacific (FTAAP) and instructed their officials to " undertake further studies on ways and means to promote " the initiative so that they could address it at their...
Autotransporters (AT) are widespread in Gram-negative bacteria, and many of them are involved in virulence. An open reading frame (APECO1_O1CoBM96) encoding a novel AT was located in the pathogenicity island of avian pathogenic Escherichia coli (APEC) O1's virulence plasmid, pAPEC-O1-ColBM. This 3.5-kb APEC autotransporter gene (aatA) is predicted to encode a 123.7-kDa protein with a 25-amino-a...
کلی باسیلوز یکی از مهمترین بیماری های باکتریایی است که صنعت طیور در تمام دنیا درگیر آن می باشد و در ایران نیز بسیار شایع است و با ایجاد تلفات، کاهش رشد و کاهش کیفیت گوشت خسارات سنگینی را به صنعت مرغداری و کشور وارد می کند. درمان این بیماری از طریق تجویز آنتی بیوتیک ها صورت می گیرد که علاوه بر تحمیل هزینه های سنگین به تولیدکنندگان باعث افزایش مقاومت میکربی و کاهش بهره برداری از پرورش طیور و کیفی...
Escherichia coli is a diverse bacterial species that comprises commensal nonpathogenic strains such as E. coli K-12 and pathogenic strains that cause a variety of diseases in different host species. Avian pathogenic E. coli strain chi7122 (O78:K80:H9) was used in a chicken infection model to identify bacterial genes that are expressed in infected tissues. By using the cDNA selection method of s...
