[Elaboration of chemotaxonomical detection method of presence Legionella pneumophila cultures in water samples by GC-MS technique].

The aim of this study was elaboration of chemotaxonomical detection method of presence Legionella pneumophila cultures in water samples. In research, the profile of ester-linked fatty acids were specified, which are situated in the cell wall of the model bacteria cultures Legionella pneumophila 33152, which originate from ATCC collection Philadelphia 1 type. The profile were applied as a standard to detection L. pneumophila presence in water supply network. During the research, water samples were esterified and extracted and then specific taxonomic markers of this bacteria were indicated by gas chromatography coupled with mass spectrometry technique (GC-MS). The limit of detection were determined to 100 jtk/100 ml water. Innovative chemotaxonomic method may be used in preliminary selection of water samples in routine analyses. Its application cuts down on time of analysis, by limitation on number of samples being diagnosed by classical microbiological methods.
