Improved Detection and Sequencing of Rickettsia spp. DNA in South African Wildlife. [PDF]

Vet Med Sci
Nested gltA PCR detected Rickettsia spp. DNA in 44% of South African wildlife samples previously negative by RLB, revealing spotted fever, typhus and transitional group lineages, novel host records, co‐infection and multi‐organ dissemination in impala, highlighting complex wildlife involvement and zoonotic risk within a One Health framework.

Diversity, Host Attachment Preferences and Role of Tick Rhipicephalus microplus in the Transmission of Bartonella spp. and Rickettsia spp. in Cattle From Southern Benin. [PDF]

Vet Med Sci
Ticks infesting cattle in Southern Benin were investigated for diversity, attachment preferences and zoonotic bacteria. Among 2210 ticks collected from 540 cattle, Rhipicephalus microplus predominated (79.6%). Ticks mainly attached to ears, axillae and trunk. PCR detection revealed Bartonella spp. and Rickettsia spp., highlighting veterinary and public

Human Spotted Fever Group Rickettsia Infecting Yaks (Bos grunniens) in the Qinghai-Tibetan Plateau Area

Pathogens, 2020
The Qinghai-Tibetan Plateau Area (QTPA) is a plateau with the highest average altitude, located in Northwestern China. There is a risk for interspecies disease transmission, such as spotted fever rickettsioses.

Molecular detection of pathogens in ticks and fleas collected from companion dogs and cats in East and Southeast Asia

Parasites & Vectors, 2020
Background Ticks and fleas are considered amongst the most important arthropod vectors of medical and veterinary concern due to their ability to transmit pathogens to a range of animal species including dogs, cats and humans.

Dissemination of spotted fever rickettsia agents in Europe by migrating birds. [PDF]

PLoS ONE, 2010
Migratory birds are known to play a role as long-distance vectors for many microorganisms. To investigate whether this is true of rickettsial agents as well, we characterized tick infestation and gathered ticks from 13,260 migratory passerine birds in ...

Association of SFG Rickettsia massiliae and Candidatus Rickettsia shennongii with Different Hard Ticks Infesting Livestock Hosts

Pathogens, 2023
Ixodid ticks are responsible for the transmission of various intracellular bacteria, such as the Rickettsia species. Little Information is available about the genetic characterization and epidemiology of Rickettsia spp.

Molecular detection of Rickettsia in fleas from micromammals in Chile

Parasites & Vectors, 2020
Background Rickettsial diseases are considered important in public health due to their dispersal capacity determined by the particular characteristics of their reservoirs and/or vectors.

Transovarial transmission of Borrelia spp., Rickettsia spp. and Anaplasma phagocytophilum in Ixodes ricinus under field conditions extrapolated from DNA detection in questing larvae

Parasites & Vectors, 2020
Background Ixodes ricinus constitutes the main European vector tick for the Lyme borreliosis pathogen Borrelia burgdorferi (sensu lato), the relapsing fever borrelia Borrelia miyamotoi, as well as Anaplasma phagocytophilum and several Rickettsia species.

Prevalence and diversity of Rickettsia species in ectoparasites collected from small rodents in Lithuania

Parasites & Vectors, 2018
Background Rickettsiae are emerging pathogens causing public health problems in many countries around the world. Rickettsia spp. are found in association with a wide range of arthropods which feed on different species of animals.

Evidence for transovarial transmission of tick-borne rickettsiae circulating in Northern Mongolia.

PLoS Neglected Tropical Diseases, 2018
Transstadial transmission of tick-borne rickettsiae has been well documented. Few studies, however, have evaluated the role of transovarial transmission of tick-borne rickettsiae, particularly in nature within the host-vector ecosystem.
