Whole cell matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for identification of Leptospira spp. in Thailand and Lao PDR
Fig 5
Principle component analysis (PCA) of protein spectra from spiked leptospires in urine and media.
Each dot displayed a protein spectrum of each sample. Color dot represent L. interrogans (Li), L. borgpetersenii (Lb), L. wolffii (Lw) and L. biflexa (Lx) in media and urine. The clustering of pathogenic, intermediate and non-pathogenic group is demonstrated in dash line.
