Partial matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) mass spectra of lipids from M. ulcerans and M. marinum. These spectra show the presence of diesters of phthiocerol and phthiodiolone, and of phenolic glycolipids in M. marinum, whereas only diesters of phthiodiolone and phenolphthiodiolone occur in M. ulcerans.
