Genome sequences of human cytomegalovirus strain TB40/E variants propagated in fibroblasts and epithelial cells
Abstract The advent of whole genome sequencing has revealed that common laboratory strains of human cytomegalovirus (HCMV) have major genetic deficiencies resulting from serial passage in fibroblasts.In particular, tropism for epithelial and endothelial cells is lost due to mutations disrupting genes UL128, tzone ball UL130, or UL131A, which encode
