The UL128-131A genomic region was PCR amplified from the TB40/E 31915, SA, SD2, SE2, CB, CD2 and CE2 stock genomes and the Sanger sequences of the UL128, UL130 and UL131A ORFs were aligned to those found in TB40/E (partial sequence, AY446866), TB40E-Lisa, RV-TB40-BACKL7-SE and two TB40-BAC4 genome sequences (TB40-BAC4 and TB40-E_UNC), and those found in two other CMV strains, UxCA, derived from urine virus and passaged exclusively in ARPE-19 cells [2], and HANRTR6, sequenced directly from the vitreous body fluid of a kidney transplant recipient with retinitis [38]. Here, CD2 is linked to retinitis.
