By comparing the MMI, agglutinin response and immunity of groups and of individual guinea-pigs which had been immunized with either B. melitensis Rev I live vaccine or B. melitensis Rev I inactivated antigen, an association between the MMI and resistance to infection was demonstrated.en©1976 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). ©2016 University of Pretoria.
