Molecular identification, genotyping of virulence-associated genes, and pathogenicity of cellulitis-derived Escherichia coli.

ABSTRACT:

Background and aim

Avian colibacillosis, which is caused by avian pathogenic Escherichia coli (APEC), is a major bacterial disease that affects birds of all ages worldwide, causing significant economic losses. APEC manifests in several clinical forms, including cellulitis, and its high pathogenicity is attributed to harboring numerous virulence-associated genes (VGs). This study evaluated the pathogenicity of the cellulitis-derived E. coli (O78) strain through molecular identification of genes coding for seven virulence factors and by conducting an in vivo assessment of capability for cellulitis induction in broiler chickens.

Materials and methods

This study was performed using a previously isolated and identified cellulitis-derived E. coli (O78),
