Before the introduction of measles, mumps, and rubella vaccine a survey was carried out to measure antibody prevalence to the three viruses by age. A total of 8716 samples of serum collected by five public health laboratories in different parts of England during 1986-7 were tested. Despite the current measles vaccination programme 60% of children aged 1-2 years did not have measles antibody and...
The elution pattern of serum proteins and the distribution of rubella HAI activity in 95 sera from 65 cases were determined after gel filtration with (a) Sephadex G-200 and (b) Bio-Gel A-5M. Rubella HAI antibody in peak 1 after Sephadex G-200 fractionation of early convalescent sera consists of both IgM and high molecular weight IgA. However, these two classes of antibody can be distinguished b...
OBJECTIVE The policy of administering the second dose of measles-mumps-rubella (MMR) vaccine (MMR(2)) has recently changed in Iran, at age 1.5 years instead of 4-6 years previously. The effects of such a change on the immune status of the individual are evaluated in this study. METHODS Totally 249 and 228 children aged 18 months and 4- to 6-year-olds, respectively, with a documented receipt o...
A technique is described for determination of rubella hemagglutination-inhibiting antibody in only 50 to 100 muliters of whole blood.
Gumpel, S. M. (1972). Archives of Disease in Childhood, 47, 330. Clinical and social status of patients with congenital rubella. Eighty-five older patients with congenital rubella attending The Hospital for Sick Children were reassessed, paying special attention to their development and adaptation to their handicaps. They were a very handicapped group of children, nearly all were deaf, over two...
Methods We did a phase 4, randomised, non-inferiority trial at three periurban government clinics in west Gambia. Infants aged 9–10 months who had already received oral poliovirus vaccine were randomly assigned to receive the IPV, measles–rubella, and yellow fever vaccines, singularly or in combination. Separately, IPV was given as a full intramuscular or fractional intradermal dose by needle a...
A method using phospholipase C (PL-C) for removing nonspecific inhibitors (NSI) of rubella virus hemagglutinin is described. PL-C was found to hydrolyze NSI without altering the hemagglutination inhibition (HI) activity of the specific antibody and could be used to remove NSI in the rubella HI test by using formalinized erythrocytes, which resisted the enzymatic action; fresh erythrocytes were ...
Developments in the United Kingdom national external quality assessment scheme for virology are described. There are about 198 participants (170 in the UK) who are enrolled for examination of any or all of five categories of specimen (distribution types). These are detection of rubella antibody (128 UK participants), detection of hepatitis B surface antigen (130 UK participants), general virus ...
Introduction:TORCH infections causing via Toxoplasma gondii, other microorganisms (e.g., Treponema pallidum), Rubella virus, Cytomegalovirus (CMV) and the Herpes Simplex Virus (HSV) types 1 and 2 during the first trimester of pregnancy can lead to severe fetal anomalies or even fetal loss. The current study determined the serological data of TORCH infections in women who were in their first tri...
Rubella hemagglutination inhibition: removal of nonspecific agglutination due to manganous chloride.
Nonspecific inhibitors of rubella hemagglutination can be removed by treatment of sera with heparin-manganous chloride for use in the hemagglutination-inhibition test. After removal of nonspecific inhibitors by this procedure, an excess of manganous chloride may remain. This may cause the cells to agglutinate, thus obscuring the reading at low serum dilutions. This disadvantage can be overcome ...
