What are the Evolutionary Origins of Mitochondria? A Complex Network Approach. [PDF]
PLoS ONE, 2015 Mitochondria originated endosymbiotically from an Alphaproteobacteria-like ancestor. However, it is still uncertain which extant group of Alphaproteobacteria is phylogenetically closer to the mitochondrial ancestor. The proposed groups comprise the order

Phylogenetic affiliation of mitochondria with Alpha-II and Rickettsiales is an artefact [PDF]
Nature Ecology & Evolution, 2022 Fan et al. challenge the finding that mitochondria represent a sister group to Alphaproteobacteria1, arguing that support for thisposition can be explained by unreliable site removal methods andoutgroup attraction. The authors chose to reduce compositionalheterogeneity by replacing AT-rich Rickettsiales and mitochondriawith GC-rich alternatives and ...

Human-pathogenic Anaplasma spp., and Rickettsia spp. in animals in Xi'an, China. [PDF]
PLoS Neglected Tropical Diseases, 2018 In China, thirteen species of tick-borne rickettsiales bacteria pathogenic to human have been reported in ticks and host animals, and human patients caused by them also has been identified. However, investigation for rickettsiales bacteria circulating in

Extensive diversity of Rickettsiales bacteria in two species of ticks from China and the evolution of the Rickettsiales [PDF]
BMC Evolutionary Biology, 2014 Les bactéries de l'ordre des Rickettsiales (Alphaproteobacteria) sont des parasites intracellulaires obligatoires qui infectent les espèces de pratiquement toutes les grandes lignées eucaryotes. Plusieurs genres rickettsiaux abritent des espèces qui sont d'importants agents pathogènes émergents et ré-émergents de l'homme.

Infection of the endothelium by members of the order Rickettsiales [PDF]
Thrombosis and Haemostasis, 2009 SummaryThe vascular endothelium is the main target of a limited number of infectious agents; Rickettsia, Ehrlichia ruminantium, and Orientia tsutsugamushi are among them. These arthropod-transmitted obligately-intracellular bacteria cause serious systemic diseases that are not infrequently lethal.

Flea-Borne Typhus Causing Hemophagocytic Lymphohistiocytosis: An Autopsy Case
Infectious Disease Reports, 2023 Infection with members of the order Rickettsiales (the genera Rickettsia, Anaplasma, Orientia, and Ehrlichia) is known to cause hemophagocytic lymphohistiocytosis (HLH). The literature is scant on flea-borne typhus (FBT) being implicated in this process.

Comparative genomics of emerging human ehrlichiosis agents. [PDF]
PLoS Genetics, 2006 Anaplasma (formerly Ehrlichia) phagocytophilum, Ehrlichia chaffeensis, and Neorickettsia (formerly Ehrlichia) sennetsu are intracellular vector-borne pathogens that cause human ehrlichiosis, an emerging infectious disease.

The SAR11 group of alpha-proteobacteria is not related to the origin of mitochondria.
PLoS ONE, 2012 Although free living, members of the successful SAR11 group of marine alpha-proteobacteria contain a very small and A+T rich genome, two features that are typical of mitochondria and related obligate intracellular parasites such as the Rickettsiales ...

Insight into diversity of bacteria belonging to the order Rickettsiales in 9 arthropods species collected in Serbia. [PDF]
, 2019 Rickettsiales bacteria in arthropods play a significant role in both public health and arthropod ecology. However, the extensive genetic diversity of Rickettsiales endosymbionts of arthropods is still to be discovered.
