FIG. 1.

Sequence comparison of the CMV gB gene in the target region for the probes in the Q-PCR assay described by Schaade et al. (14). The reference sequence in the first line is the AD169 strain, accession number X04606, 443 to 493 bp from the translational start codon. The probe sequences from Schaade et al. (14) are shown on the second line, followed by the C630T variant from Schaade et al. (15) on the third line. The last two lines of sequence are from the two isolates that were not detected by the gB Q-PCR assay (I-35 and I-60). —, sequence identity with the AD169 strain.
