Various writers (Burnet, 1928; Burnet and Conseil, 1929; Vercellara, 1929; Huddleson and Hallman, 1929; Meyer and Eddie, 1929,1930; and Weigmann, 1931) using strains of Brucella abortus, have shown that this species is very slightly pathogenic for certain species of monkeys, while Br. melitensis possesses a high degree of virulence for the same animal. I have conducted a few experiments with a view to confirming these results, using a bovine abortus and a human melitensis strain isolated in Tanganyika.
