Rickettsia rickettsii Co-feeding Transmission among Amblyomma aureolatum Ticks [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.

Autophagy facilitates intracellular survival of pathogenic rickettsiae in macrophages via evasion of autophagosomal maturation and reduction of microbicidal pro-inflammatory IL-1 cytokine responses

Microbiology Spectrum, 2023
The genus Rickettsia is comprised of obligate intracellular bacterial parasites of a wide range of arthropod and vertebrate hosts. Some Rickettsia species (spp.) are responsible for serious human diseases globally.

Pathogenic rickettsiae encode a secreted lipase that facilitates intracytosolic colonization in host cells. [PDF]

PLoS ONE
Key cellular processes for the rickettsial obligate intracellular lifestyle, including internalization by phagocytosis, regulation of intracellular trafficking, and evasion of lysosomal destruction to establish an intracytosolic replication niche, remain
