The Spread of Pyrethroid Resistance in Brown Dog Ticks: A Growing Concern for Veterinarians
The brown dog tick, Rhipicephalus sanguineus sensu lato (s.l.), poses a significant threat as a vector for Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever. Recent research has identified a mutation associated with resistance to synthetic pyrethroids (SPs), highlighting an emerging challenge in tick management.
