Risk Factors for Fecal Colonization With Multiple Distinct Strains of Escherichia coli Among Long-Term Care Facility Residents

  • Ebbing Lautenbach (a1) (a2) (a3) (a4), Pam Tolomeo (a3), Nicole Black (a3) and Joel N. Maslow (a1) (a4) (a5)


Of 49 long-term care facility residents, 21 (43%) were colonized with 2 or more distinct strains of Escherichia coli. There were no significant risk factors for colonization with multiple strains of E. coli. These results suggest that future efforts to efficiently identify the diversity of colonizing strains will be challenging.
