Table 2 Prevalence of aggR, stx1 and stx2 genes in sweep samples and prevalence of aggR, stx1, stx2, wzx O104 and fliC H4 genes in E. coli isolated from chicken faecal samples and human rectal swabs

From: Colonization of Enteroaggregative Escherichia coli and Shiga toxin-producing Escherichia coli in chickens and humans in southern Vietnam
