Detection of Rickettsia hoogstraalii , Rickettsia helvetica , Rickettsia massiliae , Rickettsia slovaca and Rickettsia aeschlimannii in ticks from Sardinia, Italy [PDF]
Ticks and Tick-borne Diseases, 2017 Tick-borne diseases represent a large proportion of infectious diseases that have become a world health concern. The presence of Rickettsia spp. was evaluated by standard PCR and sequencing in 123 ticks collected from several mammals and vegetation in Sardinia, Italy.

, 2010 Rickettsial diseases are often undiagnosed because the treating doctor doesn't consider it as part of the differential diagnosis, especially in Australia. A travel history is often helpful. For example, scrub typhus (Orientia tsutsugamushi) is only present in northern, tropical Australia; returning sick from a southern African game park may be due to ...

‘Rickettsia hulinii’ belongs to the Rickettsia heilongjiangensis species [PDF]
Clinical Microbiology and Infection, 2009 A Rickettsia species has long been defined as a distinct serotype using mouse serotyping. However, owing to a lack of reproducibility and interlaboratory comparability of this method, new taxonomic guidelines, based on multigene amplification and sequencing, have been developed and validated by an international panel of rickettsiology experts [1]. This

Inactivation of rickettsiae [PDF]
European Journal of Microbiology and Immunology, 2013 A reliable and complete inactivation is an indispensable premise for any concentration of rickettsiae or for the development of diagnostic strategies based on their antigens. This study deals with the testing of methods to inactivate rickettsiae. Rickettsia honei was used as a model organism.

THE CYTOLOGY OF RICKETTSIAE [PDF]
Journal of Experimental Medicine, 1949 Internal structures of rickettsiae seen with phase contrast microscopy and in the electron microscope contain desoxyribonucleic acid and are therefore nuclear structures similar to those found in bacteria. They are minute spherical bodies, either single as in spherical rickettsiae or varying in number from 2 to 4 in rod-shaped forms.

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
