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.

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 ...

Gene gain and loss events in
Biology Direct, 2011 Background Genome degradation is an ongoing process in all members of the Rickettsiales order, which makes these bacterial species an excellent model for studying reductive evolution through interspecies variation in genome size and gene content. In this

Acidification increases abundances of Vibrionales and Planctomycetia associated to a seaweed-grazer system: potential consequences for disease and prey digestion efficiency [PDF]
, 2018 Ocean acidification significantly affects marine organisms in several ways, with complex interactions. Seaweeds might benefit from rising CO2 through increased photosynthesis and carbon acquisition, with subsequent higher growth rates.

Microbial acetone oxidation in coastal seawater [PDF]
, 2014 Acetone is an important oxygenated volatile organic compound (OVOC) in the troposphere where it influences the oxidizing capacity of the atmosphere. However, the air-sea flux is not well quantified, in part due to a lack of knowledge regarding which ...

Two intracellular and cell type-specific bacterial symbionts in the placozoan Trichoplax H2
, 2019 Placozoa is an enigmatic phylum of simple, microscopic, marine metazoans(1,2). Although intracellular bacteria have been found in all members of this phylum, almost nothing is known about their identity, location and interactions with their host(3-6). We
