RETRACTION
Volume 43, no. 8, p. 4002–4009, 2005, https://doi.org/10.1128/JCM.43.8.4002-4009.2005. The authors hereby retract this article. The authors have been alerted that Fig. 1B, 2A, 2B, and 4A do not reflect accurate data. Specifically, in Fig. 1A, 2A, and 2B, there are rectangular lines surrounding the bands, indicative of potential splicing; and in Fig. 4A, unexpected similarities are shared between two pairs of lanes (lanes 2 and 3 versus lanes 4 and 5), suggesting potential duplication. Since the original blots are no longer available, it is not possible to submit corrected figures.
The authors sincerely regret this problem necessitating retraction of this article.
