Rickettsia amblyommatis in Ticks: A Review of Distribution, Pathogenicity, and Diversity

open access: yesMicroorganisms, 2023
Rickettsia amblyommatis is a potentially pathogenic species of Rickettsia within the spotted fever group vectored by ticks. While many studies have been published on this species, there is debate over its pathogenicity and the inhibitory role it plays in

Genomic evolution and adaptation of arthropod-associated Rickettsia

open access: yesScientific Reports, 2022
Rickettsia species are endosymbionts hosted by arthropods and are known to cause mild to fatal diseases in humans. Here, we analyse the evolution and diversity of 34 Rickettsia species using a pangenomic meta-analysis (80 genomes/41 plasmids ...

Rickettsia-Host-Tick Interactions: Knowledge Advances and Gaps

open access: yesInfection and Immunity, 2022
Ticks are hematophagous ectoparasites capable of transmitting multiple human pathogens. Environmental changes have supported the expansion of ticks into new geographical areas that have become the epicenters of tick-borne diseases (TBDs).

Bactericidal Activity of Octenidine to Various Genospecies of Borrelia burgdorferi, Sensu Lato Spirochetes in Vitro and in Vivo [PDF]

open access: yesPolish Journal of Microbiology, 2017
The aim of our studies was to invent a reliable method for detection of the bactericidal activity of disinfectants against Borrelia burgdorferi in suspension (in vitro) and in cell line cultures (in vivo). In the suspension method, 0.01% octenidine at 20&

Genomic diversity across the Rickettsia and ‘Candidatus Megaira’ genera and proposal of genus status for the Torix group

open access: yesNature Communications, 2022
The bacterial genus Rickettsia includes vector-borne pathogens and arthropod symbionts that are close relatives of symbionts of microeukaryotes classified under the genus ‘ Candidatus Megaira’. Here, Davison et al.

Rickettsia Infection Benefits Its Whitefly Hosts by Manipulating Their Nutrition and Defense

open access: yesInsects, 2022
Simple Summary Rickettsia is a maternally transmitted endosymbiotic bacterium that infects most insect species. In the current study, we investigated the biological and physiological effects of Rickettsia infection on whitefly, Bemisia tabaci.

Tick-Borne Rickettsioses in the Iberian Peninsula

open access: yesPathogens, 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.

A patatin-like phospholipase mediates Rickettsia parkeri escape from host membranes

open access: yesNature Communications, 2021
Rickettsia species of the spotted fever group are arthropod-borne obligate intracellular bacteria that can cause mild to severe human disease. These bacteria invade host cells, replicate in the cell cytosol, and spread from cell to cell.
