GALACTOSIDASE ACTION ON HUMAN BLOOD GROUP B ACTIVE ESCHERICHIA COLI AND ON RED CELL SUBSTANCES

Science
G F SPRINGERH J CALLAHAN

Abstract

The blood group B specificity of Escherichia coli O(86) antigen, a B specific oligosaccharide fraction from it, and the B activity of a preparation of an "infectious mononucleosis receptor" from cattle erythrocytes are destroyed by alpha-galactosidase from the coffee bean, as demonstrated for the E. coli antigen by three methods. Blood group H(O) activity appears simultaneously. Galactose is the only hexose released from all three substances.

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.
