[Immunization of ewes against experimental Brucella melitensis infection: comparison of eleven vaccines].
A comparative study of 11 antibrucellic vaccines has been carried out in the Limousin region of 360 ewe-lambs divided into groups of 30, a 12th group serving as control. After being vaccinated at 8 months, the ewe-lambs were covered between 9 1/2 and 10 1/2 months, then infected at 11 months with Br. melitensis strain 53 H 38 by instillation of 4 x 10(6) germs on the conjonctiva. Six of these vaccines reduced the number of abortions and the excretion of brucella at parturition: three consisted of an inactivated suspension of a virulent S strain of Br. melitensis in oily adjuvant, another consisted of an inactivated suspension of a modified non-agglutinogenic strain of Br. melitensis also in oily adjuvant, the fifth was prepared from Br. melitensis H 105 and Br. abortus B 112 with saponin and the sixth from a strain of Br. melitensis modified with aluminium hydroxide as adjuvant.
