Evasion of autophagy mediated by Rickettsia surface protein OmpB is critical for virulence. [PDF]
Nature Microbiology, 2019 Rickettsia are obligate intracellular bacteria that evade antimicrobial autophagy in the host cell cytosol by unknown mechanisms. Other cytosolic pathogens block different steps of autophagy targeting, including the initial step of polyubiquitin-coat ...

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.

Vector Borne and Zoonotic Diseases, 2021 Members of the genus Rickettsia range from nonpathogenic endosymbionts to virulent pathogens such as Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever. Many rickettsiae are considered nonpathogenic because they have been isolated

‘Rickettsia hulinii’ belongs to the Rickettsia heilongjiangensis species [PDF]
Clinical Microbiology and Infection, 2009 A Rickettsia species has long been defined as a distinct serotype using mouse serotyping. However, owing to a lack of reproducibility and interlaboratory comparability of this method, new taxonomic guidelines, based on multigene amplification and sequencing, have been developed and validated by an international panel of rickettsiology experts [1]. This
