Identification of differentially abundant proteins by two-dimensional electrophoresis (2-DE). A Bacterial proteins from M. hyopneumoniae strain 168 cultured in KM2 medium. B Bacterial proteins from M. hyopneumoniae strain 168L cultured in KM2 medium. Yellow arrows on gel images indicate the seven protein spots listed in Table 1 increased in abundance by ≥ 1.5-fold in M. hyopneumoniae strain 168.
