The HCMV glycoprotein-B N-terminus (gBn, 54 \u2212 485 NT), gB endoprotease cleavage site (gBclv, 1284 \u2212 1600 NT) and glycoprotein-H (gH, \u221258 \u2212 213 NT) gene fragments were amplified by nested polymerase chain reaction and sequenced to identify gB and gH genotypes. Of 16 gBn-positive samples, four were gBn1, one was gBn2 and 11 were the gBn3 genotype. Of 13 positive gBclv samples, seven were gBclv1, two were gBclv2 and four were the gBclv3 genotype. Of 20 positive gH samples, 10 were gH1, six were gH2 and four were a combined gH1\/gH2 genotype. In 10 of the samples that were positive for the gBn and gBclv genotypes, the gBn and gBclv genotypes were not consistent (four were gBclv1-gBn3). This study showed that: (i) HCMV infection with the gB1\u2013gB3 glycoprotein genotypes is present in tubal pregnancy; (ii) the gBclv and gBn genotypes are not strictly consistent; and (iii) intragenetic variability within the gB gene due to homologous recombination occurs frequently.<\/jats:p>","DOI":"10.1177\/147323000903700213","type":"journal-article","created":{"date-parts":[[2013,2,27]],"date-time":"2013-02-27T14:22:43Z","timestamp":1361974963000},"page":"385-391","source":"Crossref","is-referenced-by-count":5,"title":["Human
