Antimicrobial agents are used extremely in order to reducing the enormous losses caused by Escherichia coli infections (colibacillosis) in Iran poultry industry. In this investigation fifty avian pathogenic Escherichia coli (APEC) strains isolated from broiler chickens with colisepticemia and examined for susceptibility to antimicrobials of veterinary and human significance. In vitro antibiotic...

Background and Aim: With the development of industrial maintenance technology, a group pathogens called avian pathogenic Escherichia coli (APEC) became very common. The initiation, development, outcome infectious process mediated by virulent APEC strains occur through decrease in colonization resistance intestine, an immunobiological marker homeostasis stability susceptible species. This study ...

A BSTR ACT. Colibacillosis is an important disease affecting the poultry industry in many countries, caused by the Avian Pathogenic E. coli (APEC): it manifests as various clinical signs. It contributes significantly to economic loss for poultry farmers as a result of high mortality and morbidity in poultry. To overcome this, antibiotics have been widely used to eliminate E. coli infection in p...

BACKGROUND Locomotor disorders and infections by Escherichia coli represent major concerns to the poultry industry worldwide. Avian pathogenic E. coli (APEC) is associated with extraintestinal infections leading to respiratory or systemic disease known as colibacillosis. The most common lesions seen in cases of colibacillosis are perihepatitis, airsacculitis, pericarditis, peritonitis/salpingit...

Seventy poultry farms’ drinking water was tested for Escherichia coli contamination in Qom province inIran. The cases of colibacillosis from positive farms were also collected and tested. The isolates wereexamined for serotype, detection of virulence genes by multiplex PCR and antibiotic resistance. Thirtypoultry farm water samples were E. coli positive (18.57%), although 13 E. coli isolates we...
