Table 1 Indirect ELISA to compare reactivity of recombinant GP proteins from EBOV, SUDV, RESTV, BDBV, TAFV, BOMV and MARV with polyclonal antibodies against all seven viruses (++++ = O.D. > 4.0, +++ = O.D. 3.0–4.0, ++ = O.D. 2.0–3.0, + = O.D. > 0.5–2.0). - = non-reactive. As expected, some cross-reactivity does occur but differential detection of antibodies against a specific virus is possible
