Nitric Oxide Inhibition of Rickettsia rickettsii. [PDF]

open access: yesInfect Immun, 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 ...

Comparative Susceptibility of Different Populations of Amblyomma sculptum to Rickettsia rickettsii. [PDF]

open access: yesFront Physiol, 2019
The bacterium Rickettsia rickettsii is the etiological agent of Brazilian spotted fever (BSF), which is transmitted in Brazil mainly by the tick Amblyomma sculptum. Herein, larvae and nymphs of six populations of A. sculptum were exposed to R. rickettsii

Regulator of Actin-Based Motility (RoaM) Downregulates Actin Tail Formation by Rickettsia rickettsii and Is Negatively Selected in Mammalian Cell Culture. [PDF]

open access: yesmBio, 2022
The mechanism of actin-based motility of spotted fever group Rickettsia has been studied extensively, but here, we provide genetic evidence that motility is a regulated process in R. rickettsii.
