摘要：

The Campylobacter species strains (n = 42; isolated from clinical samples and deposited in Czech National Collection of Type Cultures, Prague) originally phenotypically (and biochemically) identified as Campylobacter jejuni were re-classified using molecular biological and mass spectrometric methods. Whole-cell MALDI-TOF MS (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry) separated the isolates into two genetically related strains - C. jejuni (n = 26) and C. coli (n = 16) and, moreover, distinguished the intimate details in the group of tested strains. It also made it possible to create the MALDI-TOF MS dendrogram; similarly, the spectral characteristics were used for the 3D cluster analysis. Polymerase chain reaction (PCR) confirmed the results obtained by mass spectrometry. Both methods (PCR and MALDI-TOF MS) gave the same results which supports their suitability in the rapid and accurate Campylobacter-species determination.
