RickA Expression Is Not Sufficient to Promote Actin-Based Motility of Rickettsia raoultii [PDF]
BACKGROUND: Rickettsia raoultii is a novel Rickettsia species recently isolated from Dermacentor ticks and classified within the spotted fever group (SFG). The inability of R. raoultii to spread within L929 cells suggests that this bacterium is unable to

Molecular evidence of Rickettsia raoultii, “Candidatus Rickettsia barbariae” and a novel Babesia genotype in marbled polecats (Vormela peregusna) at the China-Kazakhstan border [PDF]
In this study, two road-killed marbled polecats (Vormela peregusna) were molecularly analysed for tick-borne pathogens. Rickettsia raoultii, “Candidatus Rickettsia barbariae” and a novel Babesia genotype have been identified, for the first time in ...

Visual closed dumbbell-mediated isothermal amplification (CDA) for on-site detection of Rickettsia raoultii [PDF]
Spotted fever group (SFG) rickettsioses are important zoonoses, threatening human health seriously and gradually attracting more attention in the world. SFG rickettsiae are classified as neglected pathogens. If these pathogens are detected at all, they are usually recognized very late in the infection through indirect detection of specific antibodies ...

Genome Sequence of the Tick-Borne Pathogen Rickettsia raoultii [PDF]
ABSTRACT Rickettsia raoultii is a tick-associated spotted fever group (SFG) organism, causing scalp eschar and neck lymphadenopathy after tick bite (SENLAT) in humans. We report here the genome sequence of R. raoultii strain Khabarovsk T (CSUR R3 T
