Minimal Duration of Tick Attachment Sufficient for Transmission of Infectious Rickettsia rickettsii (Rickettsiales: Rickettsiaceae) by Its Primary Vector Dermacentor variabilis (Acari: Ixodidae): Duration of Rickettsial Reactivation in the Vector Revisited. [PDF]
J Med Entomol, 2020 It has been reported that starving ticks do not transmit spotted fever group Rickettsia immediately upon attachment because pathogenic bacteria exist in a dormant, uninfectious state and require time for ‘reactivation’ before transmission to a ...

Efficacy of afoxolaner against Dermacentor variabilis ticks in dogs
Veterinary Parasitology, 2014 Efficacy of afoxolaner, a novel isoxazoline insecticide/acaricide, against Dermacentor variabilis ticks was confirmed in two laboratory studies. Each study utilized a controlled, randomized block design. One day prior to treatment, beagle dogs were infested with 50 unfed adult ticks. Repeat infestations were performed weekly for four weeks.
