  • identification of urinary tract pathogens after 3 hours urine culture by maldi tof mass spectrometry
    Journal of Microbiological Methods, 2016
    Co-Authors: Johanna Haiko, Risto Hilla, Laura E Savolainen, Anu Patarisampo
    Abstract:

    Abstract Complicated urinary tract infections, such as pyelonephritis, may lead to sepsis. Rapid diagnosis is needed to identify the causative urinary pathogen and to verify the appropriate empirical antimicrobial therapy. We describe here a rapid identification method for urinary pathogens: urine is incubated on Chocolate Agar for 3 h at 35 °C with 5% CO 2 and subjected to MALDI-TOF MS analysis by VITEK MS. Overall 207 screened clinical urine samples were tested in parallel with conventional urine culture. The method, called U-si-MALDI-TOF ( u rine s hort i ncubation MALDI-TOF), showed correct identification for 86% of Gram-negative urinary tract pathogens ( Escherichia coli , Klebsiella pneumoniae , and other Enterobacteriaceae), when present at > 10 5  cfu/ml in culture ( n  = 107), compared with conventional culture method. However, Gram-positive bacteria ( n  = 28) were not successfully identified by U-si-MALDI-TOF. This method is especially suitable for rapid identification of E. coli , the most common cause of urinary tract infections and urosepsis. Turnaround time for identification using U-si-MALDI-TOF compared with conventional urine culture was improved from 24 h to 4–6 h.

  • in vitro susceptibility of bartonella species to 17 antimicrobial compounds comparison of etest and Agar dilution
    Journal of Antimicrobial Chemotherapy, 2006
    Co-Authors: Christina Dorbecker, Anna Sander, Karin Oberle, Tanja Schulincasonato
    Abstract:

    OBJECTIVES: In vitro susceptibility testing of 31 Bartonella spp. strains including 21 Bartonella henselae isolates was performed for 17 antimicrobial agents (telithromycin, four macrolides, five fluoroquinolones, five aminoglycosides, doxycycline and rifampicin). METHODS: MICs were determined by Agar dilution and Etest using Chocolate Agar containing 5% defibrinated sheep blood as assay medium. Longer incubation periods of 3-5 days in a humid atmosphere with 5% CO(2) were required until bacterial growth became visible and MICs could be read. RESULTS: The ketolide telithromycin was the most active agent exhibiting the lowest MICs. The Bartonella spp. were also highly susceptible to macrolides, particularly clarithromycin, and to doxycycline and rifampicin, with MICs of Agar dilution. CONCLUSIONS: Telithromycin, macrolides, doxycycline and rifampicin were the most effective agents against Bartonella spp. Our data confirm that Etest may be a reliable method for determining susceptibility of Bartonella spp.
