Ten sexually immature rams were experimentally infected with Brucella ovis,
to verify the antibody kinetics and its localization in urinary and genita
l tracts. All animals became positive to the complement fixation test from
the 2(nd) post infection (p.i.) week and reached the maximum titre (1:256)
on the 4(th) p.i. week. Bacteriemia was demonstrated on 3(rd), 4(th) and 5(
th) p.i. weeks. Two animals, respectively slaughtered 11 and 13 weeks after
the infection, showed macroscopic and microscopic genital lesions and the
etiologic agent was cultured from their urine and genital organs.
