Figure 4From: The central region of the msp gene of Treponema denticola has sequence heterogeneity among clinical samples, obtained from patients with periodontitis 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.Back to article page
