title: Isoprenoid quinone composition of representatives of the genus Campylobacter.
abstract: The isoprenoid quinone composition of 17 strains representing nine species or sub-species of the genus Campylobacter was investigated. All strains produced similar respiratory quinone patterns consisting of unsaturated menaquinones with six isoprene units and a novel unidentified quinone. Mass spectral analysis indicate the unknown compound has six isoprene units and a formula C42H58O2. The present study indicates respiratory quinones may be useful generic markers for Campylobacter.
