Abstract
Parvovirus (PV) is a widespread infection, despite the fact that this pathogen was discovered only recently. The therapeutic effect of PV, in particular its oncolytic activity, is being actively studied now. Notably, PVs causing infections in animals, such as rat PV H-1, caninae PV, and rodent protoparvovirus (minute virus of mice) suppress oncogenesis in these animals. There is an ex vivo evidence of rat glioblastoma and gliosarcoma sensitivity to PV. The affinity of PV B19 to P-antigen located primarily on the membranes of erythroid cells is crucial for the disease pathogenesis. The teratogenic effect of PV B19 is associated with its ability to infect placental cells (P-antigen is present on the cells of chorionic villi and surface of the trophoblast). PV infection can be acquired or congenital, typical or atypical. The outcome of intrauterine infection with PV B19 largely depends on the gestation age when the infection occurred. Women infected during the second trimester are at higher risk of vertical transmission and severe intrauterine pathology with a poor outcome than those infected during the third trimester. Constant contact with young children significantly increases the risk of PV B19 infection among pregnant women with no immunity to this virus. Serum is the most convenient biomaterial for detecting both PV DNA and virus-specific antibodies. One test for anti-PV IgG using enzyme-linked immunosorbent assay is sufficient to determine the immune status of a patient. Polymerase chain reaction with amniotic fluid is used to diagnose intrauterine infection with PV B19. Blood components and products should be checked for PV B19. High frequency of PV B19 detection in the blood of donors necessitates the development of special measures aimed at prevention of virus transmission. Key words: pregnant women, children, parvovirus B19, parvovirus infection
