Enzyme immunoassay (EIA) systems for measles virus and rubella virus were studied from the standpoints of requirements for suitable viral antigens and control antigens, and the sensitivity and specificity of the tests for detecting antibody elicited by past infection (determination of immunity status), and for serodiagnosis of currenet infections. Crude or semipurified measles virus antigens we...

Background and Aims: Primary infections of rubella and human cytomegalovirus (HCMV) can lead to severe complications in pregnancy. The screening of Rubella and HCMV in pregnant women is not routinely carried out in Iran. This cross sectional study aimed to investigate the seroprevalence of HCMV and rubella infections in neonates with and without congenital defects. Materials and Methods: This s...

Rubella remains a social and economic burden due to the high incidence of congenital rubella syndrome (CRS) in some countries. For this reason, an accurate and efficient high-throughput measure of antibody response to vaccination is an important tool. In order to measure rubella-specific neutralizing antibodies in a large cohort of vaccinated individuals, a high-throughput immunocolorimetric sy...

introduction: measles is a severe contagious disease preventable by vaccination. besides the prevalence of measles in iran, ministry of health conducted a nation-wide vaccination against measles for all the 5-25 years old population in 2003. this study was done to evaluate the anti measles igg antibody among the medical students from baqiyatallah university of medical science. materials & metho...

We examined correlations between serum antibody levels to determine whether individuals with low levels of antibody to one component of the measles, mumps, and rubella (MMR) vaccine were also likely to have low antibody levels to the other MMR vaccine components. Our results indicate that children who had a low antibody level to one component of the MMR vaccine had a modest probability of havin...

background: erythropoietin (epo) was first known as a factor for red blood cell proliferation and differentiation. new studies show the effects of epo on immune system. objective: in this study, the effects of pretreatment with recombinant human erythropoietin (rhuepo) on the anti-human leukocyte antibody (anti-hla) titer were determined. methods: three groups of rats were sensitized with human...

A Vero cell line with a long-term rubella virus persistent infection was maintained for 45 weeks in the presence of anti-rubella virus antibody of sufficient titer to completely neutralize the virus in the culture fluid to determine the effect of the presence of antibody on the maintenance of the persistent infection. Prior to antibody treatment, virus was continuously detected as plaque-formin...

BACKGROUND Potency test for control of rubella vaccine is a significant factor to qualify production line and vaccination program. For this reason, WHO recommends to use the microtitration method by both vaccine companies and control laboratories. Then the study was done to improve this test. METHODS Three rubella virus samples, including an in-house standard, a lot of vaccine and an in-proce...

objective: rubella is a viral disease with minor morbidity, unless it is contracted by a pregnant woman in early pregnancy that leads to congenitalrubella syndromes. rubella occurrence during the first trimester leads to fetal death or severe congenital defects.present study was conducted to survey the protection level against rubella in the pregnant women of gilan in iran,to be used for the va...
