Congenital hearing loss is a sensory impairment affecting the speech and language development of a child. There are various causes leading to the congenital loss of hearing. One of the most common causes is the infection due to Rubella virus [1]. Rubella (German measles) is contagious viral infection caused by Rubella virus (RuV) to the fetus during pregnancy [2] WHO (World health organisation)...

In congenital rubella an acid-labile alpha-interferon was present in sera collected from fetuses between weeks 21 and 29 of gestation and from children with active congenital rubella. This interferon was different from the interferon detected in normal amniotic fluid and was not found in sera from uninfected fetuses or from children with postnatally acquired rubella. The fetal interferon is of ...

OBJECTIVE To evaluate the performance of a newly developed point-of-care test (POCT) for the detection of measles-specific IgM antibodies in serum and oral fluid specimens and to assess if measles virus nucleic acid could be recovered from used POCT strips. METHODS The POCT was used to test 170 serum specimens collected through measles surveillance or vaccination programmes in Ethiopia, Malay...

We have developed and tested a method for printing protein microarrays on glass slides and using these microarrays in a comparative fluorescence assay to detect TORCH infections. We generated protein microarrays by printing antibodies to simultaneously determine infections of TORCH (toxoplasmosis-rubella-cytomegalovirus-herpes) by detecting antibodies against Toxoplasma gondii, rubella virus, c...

In vitro rubella virus infections of lymphocytes from normal adult humans impaired their responsiveness to phytohemagglutinin (PHA) stimulations; a situation which seemed analogous to the PHA unresponsiveness of peripheral lymphocytes from babies with the congenital rubella syndrome. Such in vitro viral infection of normal cells also decreased the synthesis of normal nucleic acids and structura...

Viral infections during pregnancy are a significant cause of infant morbidity and mortality. Of these, rubella virus infection is a well-substantiated example that leads to miscarriages or severe fetal defects. However, structural information about the rubella virus has been lacking due to the pleomorphic nature of the virions. Here we report a helical structure of rubella virions using cryo-el...

BACKGROUND Infection of mothers with Rubella virus during pregnancy can be serious; if the mother is infected within the first 20 weeks of pregnancy she is likely to have miscarriage, stillbirth, or baby with congenital rubella syndrome. This study was carried out to define Rubella virus seroprevalence in pregnancy in Osogbo, Nigeria. METHODS This study is a cross-sectional sero-survey of rub...

Rubella is an acute, contagious viral infection caused by a teratogenic enveloped single-stranded RNA virus, rubella virus, a member of the togaviridae family. Though causing generally mild infections in children and adults, it is a disease of public health importance in pregnant women causing major problems including abortions, miscarriages, and congenital rubella syndrome in more than 20% of ...

Cerebrospinal fluid (CSF) and serum of 17 patients with HAM/TSP (HTLV-I associated myelopathy/tropical spastic paraparesis), six with multiple sclerosis and six with idiopathic epilepsy (non inflammatory control) from Brazil were analysed for the presence of intrathecal synthesis of virus-specific antibodies against measles, rubella, varicella zoster virus and herpes simplex virus by enzyme-lin...

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...
