title: [Immunogenic and protective characteristics of recombinant Lassa virus NP protein].
abstract: Recombinant fragment of Lassa virus (strain Josiah) nucleocapsid protein (corresponding to amino acid residues 141 + 569) constructed by Dr. Jan ter Meulen (Tropenmedizine, Hamburg) was used for immunizing CBA/calac mice. The preparation was injected intraperitoneally twice with 2-week interval in a dose of 10 micrograms. The parameters of the resultant specific humoral and cell-mediated immunity were comparable to those in reference animals immunized with inactivated Lassa virus. Challenge with Lassa virus (10,000 PFU) resulted in 100% death of the reference animals, while of 15 animals immunized with the recombinant NP protein 8 survived.
