title: [Reaction of anti-I auto-antibodies with erythrocytes from the pig and monkey].
abstract: Starting from 5 human sera containing anti-I cold autoagglutinins, it was possible, using adsorption/elution trials with pig's and rhesus monkey's RBC, to separate 8 anti-I antibodies because 3 of the initial sera were heterogeneous. Each of them had 2 anti-I different as regards the reactivity with the animal RBC and the anti-ID or the anti-IF reactivity. On the whole, among 8 separated fractions 1 reacted only on pig's RBC and had the characteristics of an anti-ID; 3 reacted only on rhesus monkey's RBC and were anti-IF; 4 had a cross-reactivity with pig's and monkey's RBC: 2 of them were anti-IF and 2 anti-ID. Anti-ID fixed preferably on pig's RBC and anti-IF on rhesus monkey's RBC but monkey's RBC are not entirely lacking in ID determinants and pig's RBC in IF determinants.
