<p>The invention concerns retroviral strains of the group HIV-1, non-M non-O, particularly a strain called YBF30, its fragments and its applications as diagnosis reagent and as immunogenic agent. The HIV-2 different both from the group M and from the group O have the following characteristics: little or no serological response with respect to proteins of groups M and O and strong serological response with respect to proteins derived from the YBF30 strain or the SIV CPZGAB strain; absence of genomic amplification by the primers of regions env and gag of the HIV-1-1 of groups M and O; genomic amplification in the presence of the primers derived from the YBF30 strain; and homology of the envelope gene products higher than 70 % with respect to the YBF30 strain.</p> |
