Experimental infection of horses with Rickettsia rickettsii [PDF]
Parasites & Vectors, 2016 Rickettsia rickettsii is vectored by ticks, and some vertebrate hosts can be sources of infection to ticks during bacteremic periods. In Brazil, the main vector for R. rickettsii is the tick Amblyomma sculptum, a member of the A. cajennense complex. Horses, in turn, are one of the major hosts for A. sculptum.

STUDIES ON RESISTANCE TO BACTERIAL INFECTIONS IN ANIMALS INFECTED WITH RICKETTSIAE [PDF]
The Journal of Experimental Medicine, 1956 Data are presented, demonstrating that infection with Rickettsia typhi brings about a reduction of the death rates and a prolongation of the time of survival in animals subsequently challenged with Pasteurella pestis or Pasteurella tularensis. This interference with bacterial infection by previous rickettsial infection does not appear ...
