BACKGROUND The persistence of antibodies against measles, mumps, and rubella induced by the measles-mumps-rubella (MMR) vaccine and the kinetics of antibody decline after the second MMR vaccine dose were studied in the same cohort for 20 years. METHODS Measles, mumps, and rubella antibodies were measured by enzyme immunoassay in 20-year follow-up serum samples (n= 183) of twice-vaccinated ind...

Rubella virus is a member of family Togaviridae that usually causes a mild, self limiting infection in children and adults. The virus is of high public health significance owing to its ability to cause congenital rubella syndrome (CRS), abortion and still births. The clinical spectrum of CRS includes complete or partial blindness, sensorineural hearing defects, mental retardation, psychomotor d...

An automated microparticle enzyme immunoassay (IMx Rubella IgG Antibody Assay; Abbott Laboratories, North Chicago, Ill.) was compared with a conventional enzyme-linked immunosorbent assay (ELISA) for detection of rubella-specific immunoglobulin G (IgG) in 400 consecutive antenatal patients. There was complete agreement between the two tests in this population, which had a positivity rate of 99%...

This study was conducted to assess immunity (seroprevalence) to rubella among Jordanian women of childbearing age. A multistage cluster sampling was used to recruit 1125 women of childbearing age (15-49 year) from the 12 Governorates of Jordan. Anti-rubella antibody titers were measured using enzyme-linked immunoassays. The overall immunity rate to rubella among women in childbearing age was 90...

The study recorded for the first time in Egypt presence of tomato spotted wilt virus (TSWV) on cucurbits, which was confirmed using several serological tests, like double antibody sandwich ELISA (DAS-ELISA); Dot-blot assay and Immuno capture polymerase chain reaction (IC-PCR).  By Dot blot immunoassay test against TSWV antisera, ability thrips species Thrips tabaci (Lind), palmi (Karny), Frankl...

Ten patients with chronic liver disease, seven healthy seropositive individuals with a remote history of rubella, and three patients with acute rubella were examined for serum levels of IgG subclasses and subclass antibodies against rubella virus structural proteins. One patient with AICAH had no detectable total or rubella specific IgG3 or IgG4. The liver disease patients were hypergammaglobul...

SEVERAL STUDIES ~' ~ have shown that successful rubella vaccination of rubella-susceptible mothers in the immediate postpartum period does not lead to the appearance of detectable levels of rubella H A l antibodies in the children. The absence of antibodies is not related to the type of feeding (breast or formula) and no attempts have been made to detect rubella virus in the mother 's milk. Rec...

Peripheral blood polymorphonuclear leukocytes, mononuclear cells, and plasma and nasopharyngeal specimens were obtained from 6 subjects with persistent symptoms following rubella immunization, 1 subject with persistent symptoms following rubella, 11 children with juvenile rheumatoid arthritis, 17 recently immunized control subjects, and 1 control subject with acute clinical rubella. Rubella vir...

During a period of 7 years (1997-2003) we were received pairs of serum and CSF of 27 suspicious clinically cases from neurology department of several hospitals in Tehran. Among them 7 were serologically positive for progressive rubella panencephalitis (PRPE) and 2 were positive for sub acute sclerosing panencephalitis (SSPE). Rubella virus was isolated from 4 of 7 serologically positive cases o...

We report upon the application of quantum dot barcodes prepared by layer-by-layer biological self-assembly of quantum dot-biotin and quantum dot-streptavidin conjugates on magnetic beads for qualitative multiplexed immunoassay.
