Complete Genome Sequence of the Avian Pathogenic Escherichia coli Strain APEC O18

Colibacillosis, caused by avian pathogenic Escherichia coli (APEC), is one of the most significant infectious diseases affecting turkeys, layers, and broilers. Here we describe the sequence of first APEC O18 serotype fully complete and closed. This O18 strain was isolated from the pericardium/lung of a chicken. Functional analysis of the genome will enhance the community’s knowledge of the pathogenesis of avian pathogenic E. coli.
