Abstract
Phylogenetic relationships of Campylobacter hyointestinalis subspecies were examined by means of 16S rRNA gene sequencing. Sequence similarities among C. hyointestinalis subsp. lawsonii strains exceeded 99.0 %, but values among C. hyointestinalis subsp. hyointestinalis strains ranged from 96.4 to 100 %. Sequence similarites between strains representing the two different subspecies ranged from 95.7 to 99.0 %. An intervening sequence was identified in certain of the C. hyointestinalis subsp. lawsonii strains. C. hyointestinalis strains occupied two distinct branches in a phylogenetic analysis of the genus Campylobacter, emphasizing the need for multiple strain analysis when using 16S rRNA gene sequence comparisons for taxonomic investigations.
