Dispersal of the Lyme disease spirochete Borrelia burgdorferi to salivary glands of feeding nymphal Ixodes scapularis (Acari: Ixodidae)
J Piesman. J Med Entomol. 1995 Jul.
Abstract
Salivary gland explant cultures from 3/16 (19%) of unfed nymphal Ixodes scapularis Say contained Lyme disease spirochetes, increasing to a maximum of 14/16 (88%) at 72 h of tick feeding. Homogenates of tick salivary glands did not produce infection in laboratory white mice unless harvested from ticks attached for > or = 60 h. Dispersal of spirochetes to the salivary glands appears to occur during the act of tick feeding, thus affecting the ability of ticks to transmit Borrelia burgdorferi.
