The Distinct Transcriptional Response of the Midgut of Amblyomma sculptum and Amblyomma aureolatum Ticks to Rickettsia rickettsii Correlates to Their Differences in Susceptibility to Infection

Frontiers in Cellular and Infection Microbiology, 2017
Rickettsia rickettsii is a tick-borne obligate intracellular bacterium that causes Rocky Mountain Spotted Fever (RMSF). In Brazil, two species of ticks in the genus Amblyomma, A. sculptum and A.

RICKETTSIAE (AS ORGANISMS)

Annual Review of Microbiology, 1969
Although most pathogenic rickettsiae are obligate intracellular parasites, it is clear that they are bacteria. As such, form and function in rickettsiae are closely similar to form and function found in their free-living counterparts. This review of rickettsiae as bacteria portrays the broad similarities of rickettsiae and free-living bacteria, as well
