Differentiation of Bordetella avium and related species by cellular fatty acid analysis

Abstract

The fatty acids of 18 strains of Bordetella avium, 3 strains of Alcaligenes faecalis, 5 strains of Bordetella bronchiseptica, and 12 strains of a B. avium-like organism were examined by gas chromatography-mass spectrometry. The presence of a significant amount of the acid 2-OH C(14:0) characterized B. avium and the B. avium-like organism. B. avium and the B. avium-like organism differed in their relative concentrations of C(16:1) and 3-OH C(14:0) acids. B. bronchiseptica and A. faecalis were distinguishable by comparison of the relative concentrations of C(18:0) and C(18:1) acids.
