In addition somatic antigenic components, not detectable in the parent strains, accompanied by altered morphological and biochemical characteristics as well as virulence were demonstrated. (2) Strains of Salmonella dublin showed a change of 0- and H-antigens and acid and gas production in inositol. It has not yet been established whether the new serotypes observed represent transitional variants of adaptive or mutant nature.en©1939 ARC-Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). ©2016 University of Pretoria.
