We read the article of Hayakawa et al with great interest. The report describes the growing prevalence of vancomycin-resistant Enterococcus faecalis in Michigan, a state that also has the most reports of vancomycin-resistant Staphylococcus aureus. Similar findings were reported in the tigecycline evaluation and surveillance trial (TEST). During the 2004–2009 period, 4.6% of 3,753 E. faecalis isolates were vancomycin resistant, with the highest rates of 7.6% in the East North Central region of United States. Here we report rates and trends of vancomycin-resistant E. faecalis in the East North Central region compared with national rates from 1999 to 2010.
