  • Title: Fatty acid profiles in the family Leptospiraceae.
    Author: Cacciapuoti B, Ciceroni L, Barbini DA.
    Journal: Zentralbl Bakteriol; 1990 Oct; 274(1):16-27. PubMed ID: 2261064.
    Abstract:
    Fatty acid profiles of six leptospira strains representative of genera, species, and serogroups within the family Leptospiraceae were determined by gas liquid chromatography (GLC) of fatty acid methyl ester (FAME) derivatives. The influence of methodological and biological variables on FAME profiles of the same strain was tested. FAME profiles were sharply affected by the fatty acid composition of the culture medium but not by the growth phase. Twenty-four FAME peaks were selected on the basis of their presence in repeated gas chromatographic runs of single strains. Inter-strain divergences of FAME profiles were quantified by linear regression analysis (LR). Step-wise divergences in FAME profiles were observed between strains at serogroup, species, and genus levels.
