Accelerated Transmission of Lyme Disease Spirochetes by Partially Fed Vector Ticks

Harvard School of Public Health (1993). This experiment demonstrates that partially-fed ticks will feed again, and that the Lyme bacteria inside them, having already migrated to the mouth parts of the tick, can transmit Lyme disease more rapidly during the second feeding. Includes tables.
