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

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.

Phylogenomics and analysis of shared genes suggest a single transition to mutualism in Wolbachia of nematodes [PDF]
, 2013 Wolbachia, endosymbiotic bacteria of the order Rickettsiales, are widespread in arthropods but also present in nematodes. In arthropods, A and B supergroup Wolbachia are generally associated with distortion of host reproduction.

The evolutionary origin of host association in the Rickettsiales
Nature Microbiology, 2022 AbstractThe evolution of obligate host-association of bacterial symbionts and pathogens remains poorly understood. The Rickettsiales are an alphaproteobacterial order of obligate endosymbionts and parasites that infect a wide variety of eukaryotic hosts, including humans, livestock, insects and protists.

Comparative Genomics of a Parthenogenesis-Inducing Wolbachia Symbiont. [PDF]
, 2016 Wolbachia is an intracellular symbiont of invertebrates responsible for inducing a wide variety of phenotypes in its host. These host-Wolbachia relationships span the continuum from reproductive parasitism to obligate mutualism, and provide a unique ...
