A competing interest statement was erroneously omitted for the 2nd and 4th authors, Sreedhar R. Nallapareddy and Barbara E. Murray. The Competing Interests section should read: Drs. Barbara E. Murray and Sreedhar R. Nallapareddy are co-inventors of useful improvements in COLLAGEN-BINDING PROTEINS FROM ENTEROCOCCAL BACTERIA, a patent for which the rights have been assigned to The Texas A&M University System (College Station, TX) and the Board of Regents of the University of Texas System (Austin, TX, USA).
