Classes 1 and 2 integrons in faecal Escherichia coli strains isolated from mother-child pairs in Nigeria.

Integrons are important determinants of resistance in faecal E. coli. Plasmids in integron-containing strains may contribute to dispersing resistance genes. There is a need for improved surveillance for resistance and its mechanisms of dissemination and persistence and mobility of resistance genes in the community and clinical settings.
