Abstract

Antibody prevalence to B19 virus in Japan was previously reported with 1973 and 1984 serum collections. Since then we have had two big epidemics of erythema infectiosum in Japan: 1986-87 and 1991-92. In an attempt to estimate how much those epidemics have affected seroprevalence to B19 virus infection, we studied seroepidemiology in three separate areas using a newly developed ELISA system consisting of recombinant VP1 + VP2 particle antigen. Total of 900 sera obtained in 1993 from healthy individuals living in northern, central and southwest parts of Japan were assayed for the presence of anti B19 IgG antibody. In the first, the new assay system was compared with our conventional assay system in which native B19 virus particles were used as antigen. Of 220 serum samples tested, 212 (96.4%) gave same results in both assays. Remaining 8 samples which gave variable results were those of near cut off values. We concluded that this new ELISA system can be recommended for seroepidemiological use. Antibody prevalence rates were 10% (0-4 y), 54% (5-9 y), 59% (10-14 y), 46% (15-19 Y), 38% (20-29 y), 48% (30-39 y), 64% (40-49y) and 76% (50 y-). No gender difference was observed. Comparison of antibody prevalences in 1973, 1984 and 1993 ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
