Spotted Fever Group Rickettsiae in Ticks, Germany

Emerging Infectious Diseases, 2011
To explore increased risk for human Rickettsia spp. infection in Germany, we investigated recreational areas and renatured brown coal surface-mining sites (also used for recreation) for the presence of spotted fever group rickettsiae in ticks.

Exploring the Coinfection and Genetic Diversity of Multiple Tick‐Borne Pathogens in Livestock Population of Punjab, Pakistan

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Tick‐borne diseases affecting domestic animals and humans have increased globally in recent years. Pakistan, in particular, faces a significant economic threat from ticks, where two specific species, Rhipicephalus microplus and Hyalomma anatolicum, act as vectors for various pathogens such as piroplasma, Anaplasma, Ehrlichia, and Rickettsia that pose a

Serological Screening of Rickettsia conorii and Rickettsia slovaca Infection in Wild Rodents from Castilla-La Mancha, Spain

Zoonoses
This work was aimed at increasing epidemiological knowledge of Rickettsia conorii and Rickettsia slovaca in a geographical area in Castilla-La Mancha (Spain) lacking prior data, through a seroprevalence study in potential wild rodent reservoirs.

Ectoparasites of hedgehogs: From flea mite phoresy to their role as vectors of pathogens

International Journal for Parasitology: Parasites and Wildlife, 2021
Hedgehogs are synanthropic mammals, reservoirs of several vector-borne pathogens and hosts of ectoparasites. Arthropod-borne pathogens (i.e., Rickettsia spp., Borrelia spp., and Anaplasmataceae) were molecularly investigated in ectoparasites collected on

Spotless Rickettsiosis Caused byRickettsia slovacaand Associated withDermacentorTicks [PDF]

Clinical Infectious Diseases, 2002
The pathogenic role of Rickettsia slovaca was first demonstrated in 1997 in a patient who presented with a single inoculation lesion of the scalp and enlarged cervical lymph nodes after receiving a bite from a Dermacentor tick. Subsequently, we evaluated the occurrence of R.

Carbon nanodots as photosensitizer in photodynamic inactivation of Rickettsia slovaca

Photodiagnosis and Photodynamic Therapy
Carbon quantum dots (CQDs) are promising therapeutic agent due to their pro-oxidant, antioxidant, antiviral, antibacterial, and anticancer properties when exposed to visible light irradiation. Oxidative stress in bacteria is the main reason for bacteria death after exposure to blue light photoexcited quantum dots.

Spotted Fever Group Rickettsia spp. Diversity in Ticks and the First Report of Rickettsia hoogstraalii in Romania

Veterinary Sciences, 2022
Tickborne bacterial pathogens have been described worldwide as risk factors for both animal and human health. Spotted fevers caused by Rickettsiae may cause non-specific symptoms, which make clinical diagnosis difficult.

Multi-omics Analysis Sheds Light on the Evolution and the Intracellular Lifestyle Strategies of Spotted Fever Group Rickettsia spp.

Frontiers in Microbiology, 2017
Arthropod-borne Rickettsia species are obligate intracellular bacteria which are pathogenic for humans. Within this genus, Rickettsia slovaca and Rickettsia conorii cause frequent and potentially severe infections, whereas Rickettsia raoultii and ...

Identification and Characterization of “Candidatus Rickettsia Thierseensis”, a Novel Spotted Fever Group Rickettsia Species Detected in Austria

Microorganisms, 2020
Rickettsia spp. are the second most common pathogens detected in Ixodes ricinus ticks in Austria after Borrelia burgdorferi sensu lato. Species belonging to the spotted fever group (SFG) are the causative agents for tick-borne rickettsiosis across the ...

Comparison of real-time quantitative PCR and culture for the diagnosis of emerging Rickettsioses. [PDF]

PLoS Neglected Tropical Diseases, 2012
BACKGROUND: Isolation of Rickettsia species from skin biopsies may be replaced by PCR. We evaluated culture sensitivity compared to PCR based on sampling delay and previous antibiotic treatment.
