Sequence variation within three important cytomegalovirus gene regions in isolates from four different patient populations.

ABSTRACT: We determined the nucleotide (nt) and amino acid (aa) heterogeneities of three distinct regions of the human cytomegalovirus (CMV) genome for 46 low-passage CMV isolates from four different patient populations (congenitally infected infants, children attending day-care centers, renal transplant recipients, and human immunodeficiency virus-infected individuals) and for two laboratory strains (CMV Ad169 and Towne). The gene regions for the major immediate-early (MIE) exon 4 gene (nt positions 1702 to 1982, aa positions 152 to 244), the DNA polymerase gene (nt positions 2797 to 3046, aa positions 713 to 795), and the glycoprotein B (gB) gene (nt positions 1698 to 1884, aa positions 567 to 628) were sequenced. The sequence information was used to design sets of nested PCR primers directed agai
