title: [Differentiation between B. pertussis and B. parapertussis according to their fatty acid composition].
abstract: The fatty acid composition of 3 B. pertussis strains and 2 B. parapertussis strains grown on casein-carbon agar (CCA) with 8% of sheep blood added and without blood, as well as B. parapertussis strain grown on beef-extract agar (BEA) has been studied by gas chromatography. The fatty acid profiles characteristic of B. pertussis and B. parapertussis were greatly different, as B. parapertussis has a considerable amount of methylene-hexadenocanoic acid, while containing less hexadecenoic and octadecanoic acids and more tetradecanoic acid. The fatty acid composition of 2- to 5-day Bordetella cultures grown on CCA with and without blood has no essential differences. Differences in the content of various fatty acids in B. parapertussis grown on CCA and BEA had no essential influence on the fatty acid profile. The specificity of the fatty acid composition of B. pertussis and B. parapertussis allows to use this characteristics for their differentiation.
