Avian pathogenic
APEC strains were isolated and characterised by PCR for O serogroups, virulence factor genes, antibiotic resistance, and phylogenetic groups.
O78 was the most prevalent serogroup and type A was the most frequent phylogenetic group. The
This study provided important data on the presence of virulence genes and antibiotic resistance profiles of APEC from poultry farms in eastern China.
