Coding sequences of the UL131A, UL130, and UL128 genes of human cytomegalovirus (HCMV) were found to be highly conserved among 34 field isolates from pregnant women with primary HCMV infection and their fetuses or newborns, as well as from solid organ transplant recipients and patients with AIDS. No strain clustering was observed. In contrast, sequencing of UL55 (gB coding gene) allowed the 34 isolates to be clustered into 4 genotypes. The conservation of the UL131A-UL128 locus is consistent with the conclusion that the three encoded proteins are all essential for growth of HCMV in endothelial cells and virus transfer to leukocytes.
