Physical dimensions of the chemoreceptor arrays and the flagellar motors in B. burgdorferi

Constructs	Cell no.b	Size (nm)e	Distance (nm)d,e
Chemoreceptors	19 (15)	29.2 ± 1.1 (width)	406 ± 175
		283 ± 91 (length)
Flagellar motorsa	30	13.9 ± 1.8c
1			153 ± 78
3			369 ± 106
5			607 ± 138
7			872 ± 176

^aMotor numbers represent the sequential positions of PF, e.g., 1 is the PF closest to the cell end and 7 is the farthest.

^bTotal number of cells examined (number with chemoreceptor arrays in parentheses).

^cDiameter of the PF.

^dThe distance from the chemoreceptors or flagellar motors to the cell ends.

^eValues are means ± standard deviations.
