OBJECTIVES: To determine human cytomegalovirus (HCMV) cervical reactivation in both pregnant and non-pregnant women and to ascertain whether or not it occurs in conjunction with hematogenic dissemination. METHODS: Clinical specimens were obtained from 40 pregnant and 62 non-pregnant women attended at the Ambulatory of the Gynecology-Obstetrics Unit of the Federal University of Espírito Santo (UFES) in Southeastern Brazil. Specimens under investigation were blood samples submitted to seroprevalence determination, antigenemia assay, HCMV-DNA detection, and vaginal secretion, submitted to HCMV-DNA detection. RESULTS: Viral seroprevalence was found in 98% of the women investigated, two of whom were found to be IgM positive, while no difference could be determined between pregnant and non-pregnant women. Antigenemia assay was negative in all cases. HCMV gB gene amplification was found in 5.1 and 8.5% of WBCs and in 10 and 14.5% of vaginal secretion from pregnant and non-pregnant women, respectively. CONCLUSION: The high seroprevalence observed is in accordance with previous Brazilian surveys. Antigenemia assay was unable to detect the occurrence of active infection in the immunocompetent women studied, most likely because it either occurred in a viral load undetectable by this assay or did not occur at all. Although the highest incidence of positivity was observed by gene amplification both in WBCs and secretion from non-pregnant than in pregnant women, the rate of viral detection was statistically similar for both groups.
