Replication of measles virus was restricted in human peripheral blood mononuclear cells (PBMC). However, in in vitro-infected, unstimulated cells, active synthesis of viral RNA and proteins occurred, while the release of infectious virus could not be detected. Stimulation with PHA caused a productive infection cycle comparable to the lytic infection. Replication of viral RNA was demonstrated in...

BACKGROUND Measles remains a significant cause of vaccine-preventable mortality in sub-Saharan Africa, yet few studies have investigated risk factors for measles mortality in regions of high human immunodeficiency virus type 1 (HIV-1) prevalence. METHODS Between January 1998 and July 2003, children with clinically diagnosed measles who were hospitalized at the University Teaching Hospital in ...

OBJECTIVE To identify measles virus genotypes in three cases of travelers suspected of measles infection. METHODS Samples (blood and urine) were collected for serology, virus isolation, and genotyping. Sera were analyzed for IgM antibodies against measles virus and rubella virus by enzyme-linked immunosorbent assay (ELISA) (Siemens - Marburg, Germany). Clinical samples (lymphocytes and urine)...

Measles virus infection can result in a variety of immunologic defects. We have begun studies to determine the basis for the lack of immune responsiveness to antigen and mitogen following infection. Here we present data showing that Epstein-Barr virus-transformed B-cell lines infected with measles virus produce a soluble factor that can inhibit antigen-specific T-cell proliferation and inhibit ...

Introduction Rubella virus causes -“German measles,” also known as “three-day measles.” This is usually a milder disease than red measles. Red/Hard measles or just measles is caused by Rubeola virus. The result of acute infection of the virus is a benign systematic rash which is significantly pathogenic to humans. This virus is a, positive-strand RNA virus that replicates in the cytoplasm of th...

Subacute sclerosing panencephalitis (SSPE) is a devastating "slow virus" brain disease resulting from persistent measles virus infection of neurons. The age at presentation is usually 8 to 11 years with onset usually occurring 2-10 years after measles infection. We report a 2-and-half-year-old boy who presented with progressively increasing myoclonic jerks and subtle cognitive decline. He was d...

INTRODUCTION Comprehensive evaluation of measles-specific humoral immunity after vaccination is important for determining new and/or additional correlates of vaccine immunogenicity and efficacy. METHODS We used a novel proteome microarray technology and statistical modeling to identify factors and models associated with measles-specific functional protective immunity in 150 measles vaccine re...

Virus-induced cell fusion has been studied after infection of Vero cells with measles virus. Scanning and transmission electron microscopy were combined with immunoperoxidase labeling of measles antigens to correlate viral production and distribution of virus-induced erythrocyte binding sites with progress of fusion-Release of infectious virus started before syncytia were detected and decreased...

In Mexico, measles occurred in a cyclical endemic-epidemic pattern until the early 1970s. Beginning in 1973, routine vaccination augmented by mass vaccination campaigns led to a decrease in the incidence of measles until the 1989-1990 regional pandemic, when the measles attack rate rose to 80 cases per 100000, resulting in 5899 deaths. Since the pandemic, measles elimination efforts in Mexico h...

In situ hybridization studies have been carried out on brain samples from eight cases of multiple sclerosis (MS) and 56 non-neurological and neurological controls, using single-stranded 35S-labelled RNA probes prepared against genomic RNA sequences of measles virus, canine distemper virus, rubella virus and simian virus 5. Foci of hybridization were found using probes against the measles virus ...
