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

Transmission of Rickettsia raoultii and Rickettsia massiliae DNA by Dermacentor reticulatus and Rhipicephalus sanguineus (s.l.) ticks during artificial feeding [PDF]
Background Tick-borne rickettsial pathogens are emerging worldwide and pose an increased health risk to both humans and animals. A plethora of rickettsial species has been identified in ticks recovered from human and animal patients.

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 ...

Rickettsia raoultii–like Bacteria inDermacentorspp. Ticks, Tibet, China [PDF]
To the Editor: Rickettsia raoultii is an obligate intracellular gram-negative bacterium belonging to the spotted fever group (SFG) of the genus Rickettsia. Genotypes RpA4, DnS14, and DnS28, originally isolated from ticks from Russia in 1999 (1), were designated as Rickettsia raoultii sp. nov. on the basis of phylogenetic analysis (2). R.

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

Identification of Dermacentor reticulatus Ticks Carrying Rickettsia raoultii on Migrating Jackal, Denmark [PDF]
From a migrating golden jackal (Canis aureus), we retrieved 21 live male Dermacentor reticulatus ticks, a species not previously reported from wildlife in Denmark. We identified Rickettsia raoultii from 18 (86%) of the ticks. This bacterium is associated

First molecular diagnosis of the human pathogen Rickettsia raoultii and other spotted fever group rickettsiae in Sudanese ixodid ticks from domestic ruminants. [PDF]
In this manuscript, the authors collected ixodid ticks and examined the presence of Rickettsia species by PCR. By performing sequencing and phylogenetic analysis, the authors identified the presence of four different Rickettsia species in three tick species found on three mammalian hosts.
