FIG. 1.
Alignment of the nucleotide sequences of the three Tcr genes examined in this study, tet(W) (GenBank accession no. AJ222769), tet(O) (GenBank accession no. M18896), and tet(Q) (GenBank accession no. X58717). ClustalW was used for the alignment, and nucleotides conserved relative to those of tet(W) are indicated by hyphens while gaps in the alignment are indicated by dots. Primers and TaqMan probes designed for real-time PCR assays are indicated, with the primers singly underlined and the probes doubly underlined. The nucleotide alignment is abbreviated at nucleotide 1140.
