Detection of Rickettsia raoultii in Dermacentor reticulatus and Haemaphysalis inermis ticks in Slovakia [PDF]

, 2021
Abstract Background: Rickettsial diseases, associated with the spotted fever group (SFG), constitute a growing number of newly identified rickettsia pathogens and their tick vectors, in various parts of the world. At least 15 distinct tick species owing to six genera have shown the presence of Rickettsia raoultii.

Nationwide Survey of Vector-Borne Diseases in Rodents and Mites in Korea: Anaplasma, Ehrlichia, and Rickettsia [PDF]

Animals
Rodents are reservoirs for zoonotic pathogens, making it essential to study both rodents and their ectoparasites. In 2022 and 2023, we investigated the spatial distribution of rodents and their mites across Korea, focusing on three vector-borne diseases (

Molecular Profiling of Ticks and Associated Pathogens: First Report of <i>Rickettsia sibirica</i>, <i>Rickettsia slovaca</i>, and <i>Babesia microti</i> in Ticks From Pakistan. [PDF]

Transbound Emerg Dis
Global distribution of ticks and their associated tick‐borne pathogens (TBPs) presents substantial health concerns for both humans and animals. The present study aimed to investigate the distribution, morpho‐molecular identification, and associated TBPs of diverse tick species collected from Khyber Pakhtunkhwa and Punjab provinces of Pakistan ...

First Molecular Detection of Human Pathogen Rickettsia Raoultii in Ticks from Republic of Korea [PDF]

Biologia, 2020
AbstractTicks are vector arthropods responsible for the transmission of several pathogenic agents that affect both human and animal health worldwide. In this study our objective was to analyse, using molecular tools, the bacterial community of Dermacentor reticulatus and Haemaphysalis inermis ticks collected in south-eastern Slovakia.

Isolation and Identification of Rickettsia raoultii in Human Cases: A Surveillance Study in 3 Medical Centers in China [PDF]

Clinical Infectious Diseases, 2017
Rickettsia raoultii is frequently detected in multiple tick species, whereas human infection remains scarcely studied.A surveillance study was performed at 3 sentinel hospitals in China, to recruit participants with suspected tick exposure. Rickettsia raoultii infection was identified through polymerase chain reaction, followed by sequencing, and ...

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.

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 ...
