At the threshold of symbiosis: the genome of obligately endosymbiotic ‘Candidatus Nebulobacter yamunensis’ is almost indistinguishable from that of a cultivable strain

Abstract
Comparing obligate endosymbionts with their free-living relatives is a powerful approach to investigate the evolution of symbioses, and it has led to the identification of several genomic traits consistently associated with the establishment of symbiosis. ‘Candidatus Nebulobacter yamunensis’ is an obligate bacterial endosymbiont of the ciliate Euplotes that seemingly depends on its host for survival. A subsequently characterized bacterial strain with an identical 16S rRNA gene sequence, named

Abstract
Among endosymbiotic bacterial lineages, few are as intensely studied as Rickettsiales , which include the causative agents of spotted fever, typhus, and anaplasmosis. However, an important subgroup called “ Candidatus Midichloriaceae” receives little attention despite accounting for a third of the diversity of Rickettsiales and harboring a wide range of bacteria with unique features, like the ability to infect m

Abstract
Endosymbioses between bacteria and eukaryotes are enormously important in ecology and evolution, and as such are intensely studied. Despite this, the range of investigated hosts is narrow in the context of the whole eukaryotic tree of life: most of the information pertains to animal hosts, while most of the diversity is found in unicellular protists. A prominent case study is the ciliate Euplotes , which has repeatedly taken up the bacterium Polyn

Abstract
ABSTRACT “ Candidatus Midichloria mitochondrii” is an intramitochondrial bacterium of the order Rickettsiales associated with the sheep tick Ixodes ricinus . Bacteria phylogenetically related to “ Ca . Midichloria mitochondrii” (midichloria and like organisms [MALOs]) have been shown to be associated with a wide range of hosts, from amoebae to a variety of animals, including hum

Abstract
ABSTRACTThe orderRickettsiales(Alphaproteobacteria) is a well-known group containing obligate endocellular prokaryotes. The order encompasses three families (Rickettsiaceae,Anaplasmataceae, andHolosporaceae) and a fourth, family-level cluster, which includes only one candidate species, “CandidatusMidichloria mitochondrii,” as well as several unnamed bacterial symbionts. The broad host range exhibited by the members of the “CandidatusMidichloria” clade suggests their eventual relevance for a bett
