background: decay of vaccine–induced antibody titres without boosting of the wild measles virus has been well documented. revaccination against measles has reduced the prevalence of the disease worldwide. revaccination may cause ige induced anaphylaxis. objective: to study measles igg antibody in revaccinated populations and its relation to ige induced hypersensitivity. methods: blood samples w...

The objective of this study is primarily to compare the performance of the VIDAS(®) Measles immunoglobulin (Ig)G assay to that of two other serological assays using an immunoassay technique, Enzygnost(®) Anti-measles Virus/IgG (Siemens) and Measles IgG CAPTURE EIA(®) (Microimmune). The sensitivity and the agreement of the VIDAS(®) Measles IgG assay compared to the Enzygnost(®) Anti-measles Viru...

INTRODUCTION To review measles IgM-positive cases of febrile rash illnesses in the State of São Paulo, Brazil, over the five-year period following interruption of measles virus transmission. METHODS We reviewed 463 measles IgM-positive cases of febrile rash illness in the State of São Paulo, from 2000 to 2004. Individuals vaccinated against measles < or = 56 days prior to specimen collection ...

The host-directed cleavage of measles virus fusion protein on infected lymphoid cells was studied to understand the mechanism of viral persistence in lymphoid cells in vivo. Several lymphoblastoid cell lines were infected with measles virus, and the viral glycoproteins expressed on the cell's surface were radiolabeled and analyzed for cleavage of fusion (F(0)) to F(1) by sodium dodecyl sulfate-...

Lewis rats immunized with recombinant vaccinia virus expressing the nucleocapsid (N) protein of measles virus were protected from encephalitis when subsequently challenged by intracerebral infection with neurotropic measles virus. Immunized rats revealed polyvalent antibodies to the N protein of measles virus in the absence of any neutralizing antibodies as well as an N protein-specific prolife...

Moura, Roberto A. (Chas. Pfizer and Company, Inc., Terre Haute, Ind.) and Joel Warren. Subclinical infection of dogs by canine-adapted measles virus evidenced by their subsequent immunity to canine distemper virus. J. Bacteriol. 82:702-705. 1961.-Young dogs were inoculated with virulent measles virus which had been adapted to canine kidney or human amnion cell culture. None of the animals showe...

Upon the addition of antibody to measles virus, measles virus antigens expressed on the surface of infected cells can be modulated from the cell's membrane in vitro. Removal of measles virus antigens from the surface of cells occurs relatively rapidly and is accompanied by a parallel reduction in the ability of antibody and complement to lyse these cells. Modulation of surface viral antigens ca...

A large measles virus outbreak occurred across Vietnam in 2014. We identified and obtained complete measles virus genomes in stool samples collected from two diarrheal pediatric patients in Dong Thap Province. These are the first complete genome sequences of circulating measles viruses in Vietnam during the 2014 measles outbreak.

Genotyping is an important component of measles surveillance. In this study, we report the genotypes of 30 measles viruses from cases in Canada; 6 of these were collected between 1979 and 1996 and 24 were collected from 1997 through 2002. Many measles virus genotypes were found (C1, C2, D3, D4, D5, D6, D7, D8, E, and H1). These data indicate that the predominant measles virus genotypes detected...

Immune suppression during measles accounts for most of the morbidity and mortality associated with the virus infection. Experimental study of this phenomenon has been hampered by the lack of a suitable animal model. We have used the cotton rat to demonstrate that mitogen-induced proliferation of spleen cells from measles virus-infected animals is impaired. Proliferation inhibition is seen in al...
