[The express mode of identification of agents of bacteriemias using the technique of gas chromatography-mass spectrometry].

The comparative evaluation was carried out concerning the effectiveness of generic identification of hemocultures using the technique of gas chromatography-mass spectrometry by comparison with data of common cultural method. The content of vials with positive hemoculture was analyzed using both the common microbiologic methods and the technique of gas chromatography-mass spectrometry with detection of markers of the most widespread agents of nosocomial bacteriemias: microorganisms of genus Staphylococcus, Enterococcus, Klebsiella, Escherichia, Serratia, Pseudomonas, Acinetobacter, Stenotrophomonas, Candida. The possibility of applying the technique of gas chromatography-mass spectrometry for generic express-identification of agents of bacteriemias was established. The full concurrence of results obtained by gas chromatography-mass spectrometry with the results of common bacteriologic method was revealed. The time saving of analysis during generic identification of hemocultures using gas chromatography-mass spectrometry up to three and less hours against 1.5-2 days in case of common approach. The established information can input into earlier start of etiotropic therapy under severe infections.
