Rickettsia amblyommatis in Ticks: A Review of Distribution, Pathogenicity, and Diversity
Microorganisms, 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
Scientific 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
Infection 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).

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

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