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

Rickettsia africae and Candidatus Rickettsia barbariae in Ticks in Israel [PDF]
The American Society of Tropical Medicine and Hygiene, 2014 DNA of several spotted fever group rickettsiae was found in ticks in Israel. The findings include evidence for the existence of Rickettsia africae and Candidatus Rickettsia barbariae in ticks in Israel. The DNA of R. africae was detected in a Hyalomma detritum tick from a wild boar and DNA of C.

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

Tropism and Pathogenicity of Rickettsiae [PDF]
Frontiers in Microbiology, 2012 Rickettsiae are obligate intracellular parasitic bacteria that cause febrile exanthematous illnesses such as Rocky Mountain spotted fever, Mediterranean spotted fever, epidemic, and murine typhus, etc. Although the vector ranges of each Rickettsia species are rather restricted; i.e., ticks belonging to Arachnida and lice and fleas belonging to Insecta ...

Thermostable Endotoxin of Rickettsiae [PDF]
Nature, 1946 Kligler and Oleinik1 reported the presence of a labile toxin in yolksac cultures of Rickettsise. The following experiments were designed in order to test whether the toxic effects of Rickettsiae are wholly brought about by this labile toxin, or are due also to the action of a thermostable toxin.

GENOMOSYSTEMATICS OF RICKETTSIAE
Russian Journal of Infection and Immunity, 2018 The definition of the term genome was given by the German botanist G. Winkler almost one hundred years ago in 1920. A genome definition for bacterial (rickettsia) with a single chromosome was recently presented from the perspective of information theory, biology and bioinformatics as the information chain of nucleotides.
