Plaque reduction neutralization test (PRNT) using live Ebola virus Zaire (EBOV). Using a PRNT assay with live EBOV, neutralization capacity was assessed in survivors from the 1976 Yambuku, Democratic Republic of the Congo Ebola outbreak. As highlighted, 4/14 of the Ebola survivors (ES) were able to neutralize at least 50% of live virus and 1 of the 4 neutralizing survivors had a strong enough response to neutralize 80% of virus on the PRNT. Bars represent the standard deviation obtained from the data between multiple tests conducted using serum from each ES. Abbreviation: VLP, virus-like particle.
