Antimicrobial susceptibilities of avian Escherichia coli isolates in Tabriz, Iran

A Zakeri, P Kashefi


Colibacillosis is a poultry disease of economic importance in Iran and all around the world. The aim of this study is to test the antibiotic sensitivity of Escherichia coli strains which were isolated in Tabriz. A total of 100 E. coli strains isolated from avian colibacillosis of 50 farms from 2008 to 2009 in Tabriz, were investigated for antimicrobial susceptibility. Antimicrobial resistance of isolates was found for enrofloxacin (23%) and cefalexin (26%) as less resistant antibiotics and erythromycin (100%) and tetracycline (99%) as more resistant antibiotics.

Key words: Colibacillosis, Escherichia coli, Tabriz, antimicrobial susceptibility.
