Isolation, characterization, and genotyping of Ornithobacterium rhinotracheale isolated from broiler and broiler breeder flocks in Mazandaran province, Northern Iran.

ABSTRACT:

Background

Ornithobacterium rhinotracheale (ORT) is one of the most important pathogenic bacteria which cause significant economic losses in poultry breeder countries every year. Aims: The present study was conducted to isolate and investigate the ORT isolates' biochemical, antibiotic resistance, and genotypic characteristics of in industrial poultry flocks with respiratory signs in northern Iran.

Methods

After sampling from 60 different flocks and cultivation of the samples on a selective medium, suspected colonies were subjected to biochemical and molecular identification of ORT. Then, confirmed isolates were aimed to antibiotic resistance assay, hemagglutination test, detection of pOR1 plasmid, and DNA fingerprinting to survey the variability of the i
