Characterization of Haemophilus paragallinarum by analysis of whole cell carbohydrates, fatty acids and phospholipids

Summary The whole cell carbohydrate composition of 20 strains of Haemophilus paragallinarum including strains representing all established serotypes and two NAD‐independent strains, was determined by capillary gas‐liquid chromatography. Selected strains of H. paragallinarum were analysed for their cellular fatty acids and phospholipids compositions. The gas chromatographic analysis in combination with the mass spectrometric identification of the carbohydrate derivatives revealed similar patterns with all strains investigated.
