The Epstein-Barr virus is one of the most common and persistent human viruses in the world, according to the CDC.

Scientists at UMC Utrecht have developed a new technology to efficiently isolate a specific subset of gut bacteria from fecal samples that are recognized by IgA antibodies. These "IgA-coated" bacteria ...

A new study of more than 150 COVID-19 patients shows that IgA antibodies dominate the early response to the SARS-CoV-2 virus, coming on more quickly and strongly than IgG and IgM antibodies.

IgA antibodies are the second-most common antibody family and form a core component of responses in the adaptive immune system, the portion of the immune response dominated by B cells and T cells.

Antibodies to erythrocytes or leukocytes could not be found, but a precipitating antibody reactive with IgA in donor and normal human serum was discovered in the patient's serum.

One group, who had IgA antibodies only, never succumbed to COVID-19. Participants in the other group had both IgG antibodies and T cells, and contracted the disease.
