The standard deviations were less than 9% for all samples. The percentage of expression for each lipoprotein was determined from three independent experiments.
The total percentage of DMC-cultivated spirochetes expressing the lipoprotein was significantly different from the percentage of temperature-shifted organisms expressing the lipoprotein (P ≤0.05).
The percentage of the population with surface-exposed lipoprotein was significantly less than the total percentage of organisms expressing the lipoprotein (P ≤0.05).
There was a significant difference in the percentages of DMC-cultivated and temperature-shifted organisms expressing the lipoprotein on the surface.
