AIMS To propose a universal workflow of sample preparation method for the identification of highly pathogenic bacteria by MALDI-TOF MS. METHODS AND RESULTS Fifteen bacterial species, including highly virulent Gram-positive (Bacillus anthracis and Clostridium botulinum) and Gram-negative bacteria (Brucella melitensis, Burkholderia mallei, Francisella(More)
Yersinia are Gram-negative, rod-shaped facultative anaerobes, and some of them, Yersinia enterocolitica, Yersinia pseudotuberculosis, and Yersinia pestis, are pathogenic in humans. Rapid and accurate identification of Yersinia strains is essential for appropriate therapeutic management and timely intervention for infection control. In the past decade(More)
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(More)
In the case of a release of highly pathogenic bacteria (HPB), there is an urgent need for rapid, accurate, and reliable diagnostics. MALDI-TOF mass spectrometry is a rapid, accurate, and relatively inexpensive technique that is becoming increasingly important in microbiological diagnostics to complement classical microbiology, PCR, and genotyping of HPB.

Biochemical and serological profiles of isolates of Plesiomonas shigelloides were assayed using standard procedures in isolates from various clinical samples. Seventy-four isolates, including P. shigelloides type strain, were further characterized by MALDI-TOF MS using 3-methoxy-4-hydroxycinnamic acid as matrix. Multiple ions in the 3- to 12-kDa mass range(More)
Strains of genus Citrobacter (152 isolates from 1950 to 1988 deposited in the Czech National Collection of Type Cultures, Prague) were re-classified using biological and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) methods. One-hundred thirty-six strains (ca. 90 %) were identified to the species level using the(More)
