BACKGROUND Rubella primary infection during early stages of pregnancy is associated with high risk of congenital Rubella syndrome (CRS). Prevention of CRS in the resource-limited countries requires multiple strategies. Here, we document the data on the magnitude of Rubella natural immunity among adolescent girls which is a crucial group in devising effective control strategies to prevent CRS. ...

background: improving the performance of hiv diagnosis assays is one of the most important ways to reduce hiv transmission. because of the high mutation rate of hiv, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. because integrase is one of the most conserved proteins of hiv, it may be a good target for this purpose. in this paper cloning, purification a...

Relevance. To achieve the goals of measles and rubella elimination poliomyelitis eradication programs, immunization coverage at least 95% target population is required. Objective data on state specific herd immunity are provided only by results serosurveys. In Republic Tajikistan, such monitoring not carried out regularly. Therefore, purpose study was to assess actual measles, rubella, viruses....

A reverse transcription nested PCR (RT-PCR) assay for the detection of rubella virus RNA using primers from the E1 open reading frame was established. This assay was found to be sensitive (detecting approximately two synthetic RNA copies and RNA extracted from 0.1 50% tissue culture infective dose of rubella virus) and specific; five wild-type rubella strains and four vaccine strains were detec...

Vero cells, a line of African green monkey kidney cells, failed to produce interferon when infected with Newcastle disease, Sendai, Sindbis, and rubella viruses, although the cells were sensitive to interferon. Further, infection of Vero cells with rubella virus did not result in interference with the replication of echovirus 11, Newcastle disease virus, or vesicular stomatitis virus, even in c...

Specific cell-mediated immunity (CMI) responses to rubella virus were studied in 12 children with documented congenital rubella syndrome employing a (51)Cr lymphocytotoxicity microassay. Hemagglutination inhibition antibody was detected in 11 of the 12 children, with titers ranging from 1:4 to 1:128. CMI to rubella virus was demonstrated in only 3 of the 11 antibody-positive children. The 12th ...

Rubella virus is the only member of the Rubivirus genus within the Togaviridae family and is the causative agent of the childhood disease known as rubella or German measles. Here, we report the use of cryo-electron tomography to examine the three-dimensional structure of rubella virions and compare their structure to that of Ross River virus, a togavirus belonging the genus Alphavirus. The ecto...

Background . Pseudotuberculosis remains a serious healthcare problem, which determines the expediency of developing express methods for its early diagnosis. To detect pathogen, we designed test system dot-immunoassay (DIA) based on antibodies labeled with silver nanoparticles (SNPs) isolated from hyperimmune rabbit serum obtained against killed cells Yersinia pseudotuberculosis O:1b serovariant...

OBJECTIVES Immune recognition of the major structural proteins of rubella virus by peripheral blood mononuclear cells and synovial inflammatory infiltrates of a patient with documented chronic rubella associated arthritis was compared with responses of normal healthy rubella virus immunoreactive subjects to establish if there were unusual response patterns associated with rubella associated art...
