Volume 71, no. 6, p. 4761–4770: When the epidemiological data for this investigation were collected, the study subjects were assigned codes to protect their identities. Unfortunately, one individual was not assigned the correct code; thus, p11 should be p10, and Fig. 1 should appear as shown below.
The GenBank sequence files (U68496 through U68521) have also been updated with the corrected labels and the correct topology. Furthermore, all results presented in the paper have been reevaluated and were found to be virtually identical to the published results. Thus, the published findings and conclusions remain unchanged. A detailed account of the reanalyses can be obtained from the authors.
