Identification of Acinetobacter Species Using MicrobialTrack and Benchtop MALDI-TOF MS

User Benefits

- Acinetobacter species, previously difficult to distinguish, can now be identified with high accuracy. - The MALDI-8030 benchtop MALDI-TOF MS system enables rapid and simple acquisition of MALDI mass spectra from microorganisms. - Detected proteins are analyzed using theoretical masses predicted from their amino acid sequences.

Introduction

Acinetobacter species are Gram-negative bacteria widely distributed in natural environments, including soil and river water. While some strains perform industrially useful functions, such as degrading environmental pollutants and crude oil, others, such as A. baumannii and A. haemolyticus, are pathogenic and multidrug-resistant. In addition, some of these species are difficult to identify using the MALDI-TOF MS systems currently used for microbial testing. This application news describes the identification of Acinetobacter species using MALDI-TOF MS with the MicrobialTrack software, focusing on type strains such as A. baumannii, A. haemolyticus, andA. lwoffii, which are typically challenging to identify.
