    Abstract

    Eight atypical Mannheimia isolates were isolated from lesions in roe deer (Capreolus capreolus). Traditional classification based on morphologic and physiologic traits showed that they belong to a distinct biogroup (taxon) within genus Mannheimia. Extensive phenotypic characterization suggested that the isolates should be classified as M. granulomatis, although the presence of distinct traits justified their classification into a separate biogroup within this species. Phylogenetic analyses based on 16S rRNA sequences from two roe deer isolates and 41 other Mannheimia strains supported that the roe deer isolates form a monophyletic group within M. granulomatis. The lktA genotype was present in all roe deer isolates based on Southern blot analysis, whereas the corresponding beta-hemolytic phenotype was absent in one of these isolates.
