A city-wide cytomegalovirus serosurvey was conducted in Shanghai, China, and associated parameters were calculated by employing the catalytic model. The lowest seroprevalence was 60.37%, found in the >1- to 3-year age group. The value increased rapidly with age until 25 years, when a value of 97.03% was found, caused by the high force of infection (12.69) and by the reproductive rate (8.89).
BACKGROUND Congenital cytomegalovirus infections are a leading cause of neurodevelopmental disorders in human and represent a major health care and socio-economical burden. In contrast with this medical importance, the pathophysiological events remain poorly known. Murine models of brain cytomegalovirus infection, mostly neonatal, have brought recent insights into the possible pathogenesis, wit...
Cytomegalovirus and Chlamydia trachomatis are prevalent sexually transmissible pathogens. They produce persistent infections of the cervix and have been associated with cervical neoplasia. Cytomegalovirus has also been shown to induce transformation of cells in culture. Because of the high prevalence of genital infections with these pathogens and evidence that they may have oncogenic effects on...

Prevalence of antibodies to CMV in the female population of Rawalpindi and Islambad was determined. Twenty six percent children under 2 years of age showed antibodies to CMV increasing to 61% by adolescence. Over 90% of adult and pregnant females were sero positive. Association of development of CMV antibodies to socio-economic conditions and different geographical regions is also discussed. Ne...
A total of 2,718 blood samples were analyzed in five virological laboratories for the presence of cytomegalovirus (CMV) by in-house tests and one standardized plasma PCR assay. Results from in-house tests showed remarkable variability. Detection of CMV pp65 antigen or DNA from cells was more sensitive than that by plasma CMV PCR assay.
Live attenuated strains of human cytomegalovirus are under development as vaccines to prevent birth defects resulting from congenital infections. These strains encode four proteins that inhibit surface expression of MHC class I, presumably to evade cytotoxic T-cell recognition and, perhaps, attenuate induction of immunity. To initiate studies of the role of class I down-regulation on congenital...
We conducted a cross-sectional study of beta-herpesviruses in febrile pediatric oncology patients (n = 30), with a reference group of febrile pediatric solid-organ transplant recipients (n = 9). One (3.3%) of 30 cancer patients and 3 (33%) of 9 organ recipients were PCR positive for cytomegalovirus. Four (13%) of 30 cancer patients and 3 (33%) of 9 transplant recipients had human herpesvirus 6B...
