Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in pigs, referred to as colibacillosis. The aim of this study was to optimize multiplex polymerase chain reaction (PCR) and immunohistochemistry (IHC) analyses of paraffin-embedded material to detect pathogenic E. coli strains causing colibacillosis in pigs. Multiplex PCR was optimized for fimbriae (F18, F4, F6, F5, and F41) and toxins (ty...

Avian pathogenic Escherichia coli (APEC) strains cause severe respiratory and systemic diseases, threatening food security and avian welfare worldwide. Intensification of poultry production and the quick expansion of free-range production systems will increase the incidence of colibacillosis through greater exposure of birds to pathogens and stress. Therapy is mainly based on antibiotherapy and...

Postweaning diarrhea or colibacillosis is a costly disease causing substantial mortality, as well as growth retardation, in swine production.1-3 Colibacillosis is typically associated with avid intestinal adhesion and fecal shedding of enterotoxigenic Escherichia coli (ETEC). The ETEC causing diarrhea in postweaning pigs carries the F4 (K88) or F18 fimbrial antigen in most cases.4-6 The F5 (K99...

colibacillosis is of the most common infectious bacterial diseases of poultry.a total of 170 escherichia coli isolates obtained from broiler and layer flocks implicated with colibacillosis between 2011 and 2014 were subjected to phylogenetic analysis. among 150 e. coli isolates from typical lesions of local and systemic colibacillosis, 54 (31.8%), 37 (21.7%), 36 (21.2%) and 43 (25.3%) isolates ...

Escherichia coli (E.coli) is a common bacterium that can be naturally found in the intestinal tract of birds and as result their environment. However, it cause clinical disease called colibacillosis which regarded one most important diseases poultry. Strains E.coli have ability to are described Avian Pathogenic Coli (APEC). Colibacillosis affect all ages different types poultry production inclu...

Avian pathogenic Escherichia coli (APEC) are responsible for wide ranges of extra-intestinal diseases in poultry including colibacillosis, cellulitis, coligranuloma and yolk sac infection. Numbers of virulence are considered important in the pathogenicity of these diseases. The aims of the present study were phylogenetic typing and virulence genes detection in Escherichia coli </em...

Colibacillosis caused by Escherichia coli infections account for significant morbidity and mortality in the poultry industry. Yet, despite the importance of colibacillosis, much about the virulence mechanisms employed by avian E. coli remains unknown. In recent years several genes have been linked to avian E. coli virulence, many of which reside on a large transmissible plasmid. In the present ...

Colibacillosis results from infection with avian pathogenic Escherichia coli bacteria. Healthy broilers are resistant to inhaled E. coli, but previous infection with vaccine or virulent strains of Infectious Bronchitis Virus (IBV) predisposes birds for severe colibacillosis. We investigated whether IBV affects recruitment and function of phagocytic cells and examined NO production, phagocytic a...

The study was undertaken with a view to compare clinical and laboratory diagnoses of various bacterial diseases of poultry during the period from March 2009 to February 2010 in the laboratory of the Dept. of Microbiology and Hygiene, Bangladesh Agricultural University (BAU), Mymensingh. A total of 135 sick and dead chickens (47 broilers and 88 layers) were collected from 12 different poultry fa...
