RETRACTION
Volume 42, no. 2, p. 665–669, 2004, https://doi.org/10.1128/JCM.42.2.665-669.2004. We were alerted that some negative Western blot strips look similar on retrospective inspection under magnification. Lane 10 in Fig. 1A was likely duplicated in lanes 1, 4, and 8 of Fig. 1B. Lanes 6, 7, and 9 in Fig. 1B are likely duplicates. The lapse of 18 years since publication of this paper rendered an investigation with original research materials impossible. Therefore, we took the step of immediately and proactively contacting the journal and voluntarily took the step of retracting this paper to set the scientific record straight.
