Congenital rubella syndrome (CRS) can occur in children whose mothers contract the rubella virus, sometimes called German measles, during pregnancy [2]. Depending on the gestational period when the mother contracts rubella, an infant born with CRS may be unaffected by the virus or it may have severe developmental defects. The most severe effects of the virus on fetal development occur when the ...

Rubella is a viral disease with minor morbidity and few complication unless it is contracted by a pregnant woman. Rubella infection during the first trimester of pregnancy often leads to fetal death or severe congenital defects (congenital rubella syndrome, CRS). Rubella remains endemic in many countries of Latin America and the Caribbean. It has been estimated that 20,000 or more infants are p...
Using a highly sensitive and specific chemiluminescence (CL) method, we detected the release of superoxide anion (O2-.) from human polymorphonuclear leukocytes (PMNLs) stimulated by rubella viral antigen-antibody complex (VAAC) adsorbed on latex particles. The amount of superoxide anion produced by PMNLs was proportional to the amount of VAAC. Neither rubella virus alone nor antibody alone, ads...
A collection of synovial fibroblasts from 19 patients with rheumatoid arthritis (RA) and 12 patients with osteoarthrosis or other non-RA disease has been examined for rubella virus antigens by immunofluorescence and radioimmunoassay with negative results. Eluates of synovial membrane prepared under conditions likely to dissociate antigen-antibody complexes have shown no rubella antibody. A sero...
DNA and RNA were extracted from synovial membranes, synovial fibroblast cells, peripheral blood lymphocytes, and synovial fibroblast cells strains derived from patients with rheumatoid arthritis and other joint conditions. They were hybridised after immobilisation on nitrocellulose filters with iodinated viral nucleic acids extracted from measles, rubella virus, SV--40, and a retrovirus, RD--11...
A disseminated relapsing neurological disorder presented simultaneously in two sisters. Encephalitic features were present in one case. The illness was associated with a significant increase in rubella specific IgM in both sisters. Despite the absence of a rubella rash, this increase would be compatible with a recent infection by the rubella virus as a basis for the illness, and the persistent ...
In China, rubella vaccination was introduced into the national immunization program in 2008, and a rubella epidemic occurred in the same year. In order to know whether changes in the genotypic distribution of rubella viruses have occurred in the postvaccination era, we investigate in detail the epidemiological profile of rubella in China and estimate the evolutionary rate, molecular clock phylo...
background and aims: vaccine is available, but fetal infection with rubella virus is still a main cause of congenital birth defects and mental retardation in many countries. mass vaccination campaigns and expanded program of immunization (epi) have increased vaccine coverage in the world with a substantial impact on the reduction of rubella infections, such as congenital rubella syndrome (crs)....
Background and Aims: Rubella is a contagious viral disease mostly with mild clinical symptoms and often remains undiagnosed. Rubella infection may adversely affect pregnancy, especially in the first trimester and this mother to child transmission can cause congenital rubella and may be lead to permanent disability and mortality in children. Effective rubella vaccine should be prepared using sui...
