Objective:
To investigate human cytomegalovirus (HCMV) glycoprotein B (gB) genotypes and clinical features in neonates with congenital infections.
Methods:
Urine samples were obtained from 67 neonates with HCMV infection confirmed by polymerase chain reaction (PCR). The gB gene fragment was amplified by nested PCR. HCMV gB genotyping was detected by restriction fragment length polymorphism.
Results:
In all these cases, the most prevalent genotype was gBl (50.7%), followed by gB3 (23.9%), gB2 (17.9%), and gBl/gB3 coinfection (7.5%); gB4 was not found. Moreover, gB1 was more prevalent in infants with liver damage (27/37, 73.0%) than in other symptomatic infants without liver damage (13/30, 43.3%; P < 0.05).
Conclusion:
The gBI genotype is the most prevalent in infants with congenital symptomatic HCMV disease, especially in those with liver damage, followed by genotypes gB3, gB2, and gB4.
