Nitric Oxide Inhibition of Rickettsia rickettsii [PDF]
Infection and Immunity, 2021 Rickettsia rickettsii , the causative agent of Rocky Mountain spotted fever, is an enzootic, obligate, intracellular bacterial pathogen. Nitric oxide (NO) synthesized by the inducible NO synthase (iNOS) is a potent antimicrobial component of innate immunity and has been implicated in the control of virulent ...

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.

Hosts mobility and spatial spread of Rickettsia rickettsii [PDF]
PLOS Computational Biology, 2018 There are a huge number of pathogens with multi-component transmission cycles, involving amplifier hosts, vectors or complex pathogen life cycles. These complex systems present challenges in terms of modeling and policy development. A lethal tick-borne infectious disease, the Brazilian Spotted Fever (BSF), is a relevant example of that.

Rickettsia rickettsiiCo-feeding Transmission amongAmblyomma aureolatumTicks [PDF]
Emerging Infectious Diseases, 2018 Amblyomma aureolatum ticks are vectors of Rickettsia rickettsii, the etiologic agent of Rocky Mountain spotted fever in Brazil. Maintenance of R. rickettsii in nature depends on horizontal transmission along tick generations. Although such transmission is known to occur when uninfected and infected ticks feed simultaneously on susceptible animals (co ...
