[Differentiation of Salmonella gallinarum rough and smooth strains using gas chromatography analysis of their cell-bound fatty acids]

Abstract

The whole cell fatty acids of 7 field isolates of smooth (S)-type S. Gallinarum strains and 3 isolates of rough (R)-type S. Gallinarum strain 9R were determined by the liquid-gas-chromatography using the Microbial Identification System (MIS, Microbial ID, Inc. [MIDI, Newark, Delaware USA]). The profiles of the bacterial cellular fatty acids of the S- and R-type isolates differ in the number as well as in the quantity of the fatty acids. On the basis of these differences the S-type isolates could be distinguished from the R-type cultures.
