Genetic Diversity of Pasteurella dagmatis as Assessed by Analysis of the 16S rRNA and rpoB Gene Sequences

摘要

A total of 16 Pasteurella dagmatis strains, including 11 feline and 4 canine isolates as well as one strain isolated from a tiger, were analyzed using partial 16S rRNA and rpoB gene sequence comparison. Phylogenetic studies based on both genes revealed that the population of P. dagmatis recovered from cats in Poland differs markedly from canine strains, constituting a well-separated cluster within Pasteurella sensu stricto species group. The isolate from a tiger seems to represent yet another evolutionary lineage within P. dagmatis.
