Evaluation of Dermacentor species naturally infected with Rickettsia raoultii [PDF]
Clinical Microbiology and Infection, 2009 In the present study, we investigated the efficiency of transovarial transmission and intensity of multiplication of three R. raoultii genotypes in four naturally-infected Dermacentor species. We used the method of experimental modelling of a natural cycle of the metamorphosis of vectors (MEMNCMv) that allows the study of the role of tick species as ...

Rickettsiae, obligate intracellular Gram-negative bacteria, responsible for mild to severe diseases in humans are associated with arthropod vectors. Dermacentor marginatus and Dermacentor reticulatus are known vectors of Rickettsia slovaca and Rickettsia raoultii distributed across Europe. A total of 794 D. marginatus, D. reticulatus and Ixodes ricinus

We analyzed rickettsial DNA of ticks from tick-borne lymphadenopathy (TIBOLA) patients. Dermacentor marginatus (9/17) and Dermacentor reticulatus (8/17) transmitted rickettsiae to a similar extent. Rickettsia raoultii was detected in more ticks than Rickettsia slovaca.

Since the year 2000, clinical patterns resembling tick-borne rickettsioses have been noticed in China-Russia border areas. Epidemiological data regarding species of the aetiological agent, tick vector prevalence and distribution as well as incidence of human cases in the areas are still sparse to date.

Rickettsia raoultii and Rickettsia sibirica in ticks from the long-tailed ground squirrel near the China–Kazakhstan border [PDF]
Experimental and Applied Acarology, 2019 Spotted fever group (SFG) rickettsiae cause infection in humans, domestic animals and wildlife. To date, no rickettsial agents have been reported in hard ticks from the long-tailed ground squirrel (Spermophilus undulatus). A total of 50 adult ticks and 48 nymphs were collected from S. undulatus in the border region of northwestern China.

Detection of causative agents of tick-borne rickettsioses in Western Siberia, Russia: identification of Rickettsia raoultii and Rickettsia sibirica DNA in clinical samples [PDF]
Clinical Microbiology and Infection, 2018 The main causative agent of tick-borne rickettsioses in Siberia is considered to be Rickettsia sibirica; however, only a few cases have been genetically confirmed. Other pathogenic species of Rickettsia have been detected in ixodid ticks in Western Siberia.
