F-Wave Latencies Recorded for Motor Nerves (Median, Ulnar, and Tibial) in Rhesus Macaques Inoculated Intrathecally with Live Bb and Left Untreated or Treated with Either Dex or Mel

Rhesus macaques and treatment	F-wave latencies (msec)
GN22 (Bb alone 8 weeks)	Abnormal F waves in all nerves recorded from week 2 PI until end of study Median F waves = 14.8–20.2 (UL 14.7)∗ Ulnar F waves = 15.1–22.5 (UL 14.8)∗ Tibial F waves = 21.2–30.1 (UL 20.7)∗
GB09 (Bb+Dex 8 weeks)	Normal
GP33 (Bb+Mel 8 weeks)	Normal
GN21 (Bb alone 8 weeks)	Normal
IG55 (Bb+Dex)	Normal
HH83 (Bb+Mel 8 weeks)	Normal
IK20 (control 8 weeks)	Normal
GC59 (Bb alone 14 weeks)	Normal
GJ23 (Bb+Dex 14 weeks)	Abnormal F waves in tibial nerve from week 2 PI but returned to normal by 8 weeks PI Tibial F waves = 17.2–25.1 at week 2; 16.5–19.6 at week 8 (UL 20.7)∗
GK54 (Bb+Mel 14 weeks)	Abnormal F waves in ulnar and tibial nerves recorded from week 2 PI until end of study Ulnar F waves = 16.3–24.8 (UL 14.8)∗ Tibial F waves = 22.2–33.3 (UL 20.7)∗
HT72 (Bb alone 14 weeks)	Abnormal F waves in median and ulnar nerves recorded from week 2 PI until end of study Median F waves = 15.6–22.7 (UL 14.7)∗ Ulnar F waves = 16.3–23.7 (UL 14.8)∗
GM23 (Bb+Dex 14 weeks)	Normal
GN49 (Bb+Mel 14 weeks)	Abnormal F waves in ulnar and tibial nerves recorded from week 2 PI until end of study Ulnar F waves = 15.3–19.6 (UL 14.8)∗ Tibial F waves = 23.4–31.6 (UL 20.7)∗
HT73 (control 14 weeks)	Normal

Bb, Borrelia burgdorferi; Dex, dexamethasone; Mel, meloxicam; PI, after inoculation UL, upper limit.

^∗UL of normal in controls was based on means + 2 SD. Unless noted, F-wave latencies were below the UL of normal.
