A Rickettsia Case Caused by Rickettsia conorii

Mikrobiyoloji Bulteni, 2018
Rickettsia species are gram-negative intracellular, small pleomorphic coccobacilli in the Rickettsiaceae family. This genus is serologically and genotypically divided into four groups as spotted fever group, typhus group, Rickettsia belli and Rickettsia canadensis. Rickettsia conorii (R.conorii subsp. conorii) in the spotted fever group was reported to

Coinfection of Two Rickettsia Species in a Single Tick Species Provides New Insight into Rickettsia-Rickettsia and Rickettsia-Vector Interactions

Microbiology Spectrum, 2022
Rickettsiae are obligate intracellular bacteria that can cause life-threatening illnesses. There is an ongoing debate as to whether established infections by one Rickettsia species preclude the maintenance of the second species in ticks.
