There was an error in the title and nomenclature of a paper published in the July 2007 issue of the journal (Zheng H, Murai Y, Hong M, et al. Jamestown Canyon virus detection in human tissue specimens. J Clin Pathol 2007;60:787–93.) The correct title should be as follows: JC virus detection in human tissue specimens. The journal thanks Dr James J Clayton for pointing out the error. A corrected PDF is available at http://jcp.bmj.com/supplemental
