Escherichia coli strains causing avian colibacillosis and human neonatal meningitis, urinary tract infections, and septicemia are collectively known as extraintestinal pathogenic E. coli (ExPEC). Characterization of ExPEC strains using various typing techniques has shown that they harbor many similarities, despite their isolation from different host species, leading to the hypothesis that ExPEC...

Avian Pathogenic Escherichia coli (APEC) is the contributing agent behind avian infectious disease colibacillosis, which causes substantial fatalities in poultry industries that has a significant impact on economy and food safety. Several virulence genes have been shown to be concomitant with extraintestinal survival of APEC. This study investigates antibiotic resistance patterns APEC-associate...

Avian colibacillosis is the most common bacterial disease affecting broilers. To better evaluate diversity and origin of causative Escherichia coli strains infecting birds, we conducted a study on 80 broiler flocks. Just before arrival chicks farm, samples were collected in farm environment (walls, feeders, air inlets, etc.) and, upon delivery, day-old (DOCs) transport boxes also sampled. Isola...

This study was carried out to investigate the prevalence and pathological lesions of avian colibacillosis in commercial broiler farms at Dinajpur Sadar Upazila (Sub-district) from July December 2018. A total 8800 birds six were diagnosed with clinical signs, post-mortem histopathological changes. Highest F1 farm (76.2%) lowest F6 (9.2%). mortality (9.1%) (3.3%). Average 39.6% 5.4%. at0-2 weeks ...

We have found an avian pathogenic Escherichia coli (APEC) plasmid, pAPEC-O2-ColV, which contains many of the genes associated with APEC virulence and also shows similarity in content to a plasmid and pathogenicity island of human uropathogenic E. coli (UPEC). To test the possible role of this plasmid in virulence, it was transferred by conjugation along with a large R plasmid, pAPEC-O2-R, into ...

Colibacillosis accounts for annual multimillion dollar losses in the poultry industry, and control of this disease is hampered by limited understanding of the virulence mechanisms used by avian pathogenic Escherichia coli (APEC). Previous work in our laboratory has found that the presence of the increased serum survival gene (iss) is strongly associated with APEC but not commensal E. coli, maki...

Avian pathogenic Escherichia coli (APEC) strains cause systemic and localized infections in poultry, jointly termed colibacillosis. Avian colibacillosis is responsible for significant economic losses to the poultry industry due to disease treatment, decrease in growth rate and egg production, and mortality. APEC are also considered a potential zoonotic risk for humans. Fully elucidating the vir...

Avian colibacillosis, caused by Escherichia coli, is one of the major bacterial diseases in the poultry industry worldwide, and along with salmonellosis, it is the most common avian disease communicable to humans. The organism is a normal inhabitant of the intestinal tract of birds and can survive in a wide range of temperature. Certain strains viz., avian pathogenic E. coli (APEC), however, co...
