Rickettsial pathogens drive microbiota assembly in Hyalomma marginatum and Rhipicephalus bursa ticks

Molecular Ecology, Volume 32, Issue 16, Page 4660-4676, August 2023., 2023
Abstract Most tick‐borne pathogens (TBPs) are secondarily acquired by ticks during feeding on infected hosts, which imposes ‘priority effect’ constraints, as arrival order influences the establishment of new species in a microbial community. Here we tested whether once acquired, TBPs contribute to bacterial microbiota functioning by increasing ...

Identification of two leafminer parasitoids (Hymenoptera: Eulophidae), Neochrysocharis formosa and Proacrias sp. from Australia, with both showing thelytoky and infection by Rickettsia

Austral Entomology, Volume 61, Issue 3, Page 358-369, August 2022., 2022
Abstract Liriomyza huidobrensis, L. sativae and L. trifolii are polyphagous agromyzid leafminers that have recently arrived in Australia, posing a threat to Australian vegetable and ornamental crops. Adventive and endemic hymenopteran parasitoids of agromyzid leafminers already present in Australia should assist in the management of these invasive ...

Molecular identification of zoonotic Rickettsia species in Ixodidae parasitizing wild lagomorphs from Mediterranean ecosystems

Transboundary and Emerging Diseases, Volume 69, Issue 4, Page e992-e1004, July 2022., 2022
Abstract A survey study was carried out to identify tick species parasitizing wild lagomorphs in Mediterranean ecosystems in southern Spain and to determine the occurrence of Rickettsia species present in these ticks in this region. A total of 1304 European wild rabbits (Oryctolagus cuniculus) and 58 Iberian hares (Lepus granatensis) were individually ...

Molecular identification of Theileria equi, Babesia caballi, and Rickettsia in adult ticks from North of Xinjiang, China

Veterinary Medicine and Science, Volume 7, Issue 6, Page 2219-2224, November 2021., 2021
One hundred nineteen tick samples obtained from horses in Xinjiang, China, to investigate the situation of pathogens by hard ticks. Theileria equi was detected in 1 tick, Babesia caballi was detected in 18 ticks. Among this, the mixed carriage rate of Theileria equi and Rickettsia was 0.8% (1/119), the mixed carriage rate of Babesia caballi and ...

Rickettsiae in red fox (Vulpes vulpes), marbled polecat (Vormela peregusna) and their ticks in northwestern China

Parasites & Vectors, 2021
Background Previously, twelve Rickettsia species were identified in ticks, fleas, sheep keds (Melophagus ovinus), bats (Pipistrellus pipistrellus) and a tick-bitten patient in the Xinjiang Uygur Autonomous Region (XUAR) in northwestern China.

Cutaneous immunoprofiles of three spotted fever group Rickettsia cases [PDF]

, 2020
Spotted fever group rickettsia (SFGR) can cause mild to fatal illness. The early interaction between the host and rickettsia in skin is largely unknown, and the pathogenesis of severe rickettsiosis remains an important topic.

Tick-Borne Rickettsioses in the Iberian Peninsula

Pathogens, 2022
Tick-borne rickettsioses (TBR) are caused by obligate, intracellular bacteria of the spotted-fever group (SFG) of the genus Rickettsia (Order Rickettsiales), transmitted by hard ticks.

Coinfection with "Rickettsia sibirica subsp. mongolotimonae" and Rickettsia conorii in a Human Patient: a Challenge for Molecular Diagnosis Tools. [PDF]

J Clin Microbiol, 2015
ABSTRACT Rickettsioses are zoonoses transmitted by vectors. More than one agent can coexist in vectors. Although vectors may transmit more than one microorganism to humans, information on dual infections is scarce.
