Evaluation of MSP96, MBT Biotarget™ 96 and AnchorChip™ 600/96 MALDI-TOF MS target plates for direct identification of positive blood cultures

The objective of the study was to compare the diagnostic performances of three Bruker MALDI-TOF MS target plates. A combination of two or three targets results in an increase of the identification percentage, especially in problem isolates as gram-positive cocci and yeast. •Bruker MALDI-TOF target p...

Zusammenfassung:	The objective of the study was to compare the diagnostic performances of three Bruker MALDI-TOF MS target plates. A combination of two or three targets results in an increase of the identification percentage, especially in problem isolates as gram-positive cocci and yeast. •Bruker MALDI-TOF target plates performance comparison.•Evaluation of identification scores for different Bruker MALDI-TOF target plates.•Provide an alternative MALDI-TOF target plate when no accurate identification is obtained.
