Human cytomegalovirus gB1 genotypes among children who live at the Phayathai Babies' home in Nonthaburi, Thailand.

We conducted a survey of human cytomegalovirus (HCMV) genotypes among 176 children aged 1 month to 5 years living at Phayathai Babies' Home in Nonthaburi Province, Thailand to determine the prevalence of HCMV glycoprotein B (gB) genotype. The study was conducted on urine samples using nested polymerase chain reaction and restriction fragment length polymorphism; the HCMV gB1 genotype was found in 89% of subjects, much higher than previous reports. Our results show a high proportion of HCMV gB1 infected children in this population.
