Abstract
Trypsinized human group O erythrocytes were found to be a suitable alternative to gander cells in hemagglutination (HA) and hemagglutination inhibition (HAI) tests for Japanese encephalitis (JE) virus. In the HAI test, no cross-reactions against JE virus were observed with immune sera containing antibody to taxonomically related or unrelated viruses, with mouse brain antigen, or with nonantibody serum inhibitors; specific antibody rise could be detected in an immunized rabbit. Gander and trypsinized human group O cells gave comparable titers in the HAI test, but the latter were preferable since (i) they required less challenging HA antigen, being more sensitive to agglutination by JE virus, and (ii) all human and some animal sera investigated were devoid of natural agglutinins for these cells, thereby eliminating or reducing the need for prior adsorption with packed cells.
