We investigated the prevalence of resistance in commensal Escherichia coli in preschool children in rural Vietnam, and factors associated with carriage of resistant bacteria. Methods We tested isolates of E. coli from faecal samples of 818 children aged 6-60 months living in FilaBavi, a demographic surveillance site near Hanoi.

Escherichia coli, a major part of the commensal flora of the gut, has the potential to cause a variety of infections. Commensal E. coli can act as reservoirs of resistance genes that easily transfer to other commensal E. coli, as well as other potential pathogenic bacteria ( Leverstein-van Hall et al. 2002; Livermore 2003 ).
