Spread of the individuals immunized with Mycobacterium butyricum (Group B) according to the principal component analysis (PCA). Spread of the individuals from the four lines immunized with Mycobacterium butyricum (Group B) according to the axes 1 and 2 of the principal component analysis (PCA): blue circle = line ND3-L, red = PHA-L, green = CC-L and turquoise = Control. The size of the individual circles increases with their mean contribution to the 2 axes. Trt_Init = Natural antibody titer (Nabs) to M.B. (Group B), Trt_Final = Antibody (Ab) titer after immunization with M.B., LPS-Init = Natural antibody titer (Nabs) to LPS at day 0, LPS_Final = Ab to LPS 11 days post immunization, LTA_Init = Nabs to LTA at day 0, LTA_Final = Ab to LTA 11 days post immunization, Gal*2_Init = Ab to anti-Gal epitope at day 0, Gal*2_Final = Ab to anti-Gal epitope 11 days post immunization, D_Trt = responsiveness of Ab response to M.B, D_LPS = responsiveness of Ab response to LPS, D_LTA = responsiveness of Ab response to LTA, D_GAL = responsiveness of Ab response to anti-Gal. PC1 = explains 25.44% of the variance. PC2 = explains 19.44% of the variance.
