Matrix-assisted laser desorption ionization time-of-flight mass spectrometry as a new possibility for rapid identification of bacteria and fungi revolutionized the clinical microbiological diagnostics. It has an extreme importance in the routine microbiological laboratories, as identification of the pathogenic species rapidly will influence antibiotic(More)
Sample preparation was optimized for MALDI-TOF MS directly from the selective enrichment broth to detect Staphylococcus aureus. A combination of MALDI-TOF MS and the PBP2' latex agglutination assay was applied for MRSA screening and evaluated on 255 clinical samples. MRSA colonisation can be reported already 18-24h after sample collection.
Little is known of the frequency of norovirus infections in sporadic gastroenteritis cases. In a 4-y study, we examined 1152 rota-, adeno- and astrovirus negative stool samples for human noroviruses; 187 (16.2%) proved to be positive. Stool samples were from paediatric patients with acute gastroenteritis. All isolates were verified as sporadic cases: there(More)
Scedosporium apiospermum is an emerging opportunistic filamentous fungus, which is notorious for its high levels of antifungal-resistance. It is able to cause localized cutaneous or subcutaneous infections in both immunocompromised and immunocompetent persons, pulmonary infections in patients with predisposing pulmonary diseases and invasive mycoses in(More)
Sample preparation was optimized for MALDI-TOF MS directly from selective enrichment broth to detect Streptococcus agalactiae. The method was tested on 100 vaginal samples of pregnant women; positive and negative predictive values were 100 and 91%, respectively. If it indicates positivity, colonisation can be reported 18-24h after sample collection.
