Pasteurella haemolytica complex of Pasteurella sensu stricto as new genus Mannheimia: changes in taxonomy

Abstract

The benefit and usefulness of the new results described by Angen et al. (1999) rest upon the necessity for revising the previous taxonomy of Pasteurellaceae by grouping microorganisms based on their phylogenetic relationships combined with phenotypic characters and the usefulness of molecular biological methods in determining the taxonomic structure based on genomic evidence with supplementary phenotypic data. According to authors cited the phenotypic character of each serotype, species and even genus was well defined by their morphology, growth requirements and metabolic activities. The genomic relationships of serotypes, species and genera were detected by different molecular biological techniques.
