Abstract

The use of mass spectral ionization methods to study lipid membrane profiles for the detection of Listeria sp. was discussed. The lipid membrane profiles of various Listeria sp. were acquired using different mass spectrometry techniques in order to differentiate the pathogen, Listeria monocytogenes, from related non-pathogenic strains which included L. grayi, L. inanovii, L. seeligeri and L. welshimeri. It was observed that the patterns of unsaturation in the fatty acids chains were evident and species specific. The taxanomical differences were observed in the positive mode of ionization, while structural data was observed from positive mode of ionization.
