Figure 4

Antigenicity plot of T. denticola strains ATCC 35405 (frame A), ATCC 33520 (frame B), and 2 representative specimens (B66, frame C; B23, frame D). In each frame, the area of the plot that is surrounded by a continuous line represents the central region of MSP. The internal smaller area, surrounded by the dotted line, represents the portion that has the greatest difference in predicted antigenicity between specimens B66 and B23 and ATCC35405.
