Ecological specialization to restricted diet niches is driven by obligate, and often maternally inherited, symbionts in many arthropod lineages. These heritable symbionts typically form evolutionarily stable associations with arthropods that can last for millions of years. Ticks were recently found to harbour such an obligate symbiont, Coxiella‐LE, that synthesizes B vitamins and cofactors not obtained in sufficient quantities from blood diet. In this study, the examination of 81 tick species… Expand
Microbial community structure reveals instability of nutritional symbiosis during the evolutionary radiation of Amblyomma ticks
TLDR
Examination of bacterial diversity in 25 tick species of the genus Amblyomma showed that three intracellular bacteria, Coxiella‐like endosymbionts (LE), Francisella‐LE and Rickettsia, are remarkably common, and found evidence for symbiont replacements during the radiation of AmblyMA, with recent, and probably ongoing, invasions by Francisella-LE and subsequent replacements of ancestral Coxiellas through transient co‐infections. Expand
Ecological Contacts and Host Specificity Promote Replacement of Nutritional Endosymbionts in Ticks.
TLDR
It is demonstrated that Francisella-LE commonly transfer through similar ecological networks and geographic distributions shared among different tick species and, in certain cases, through preferential shuffling across congeneric tick species. Expand
Sequence of a Coxiella endosymbiont of the tick Amblyomma nuttalli suggests a pattern of convergent genome reduction in the Coxiella genus
TLDR
The genome sequence of a novel Coxiella, endosymbiont of the African tick Amblyomma nuttalli is provided and it is inferred that this pathogen could be closer to an ancestral state of the endosYmbionts, rather than being derived from an endos ymbiotic ancestor, as previously hypothesized. Expand
Sequence of a Coxiella Endosymbiont of the Tick Amblyomma nuttalli Suggests a Pattern of Convergent Genome Reduction in the Coxiella Genus
TLDR
The genome sequence of a novel Coxiella, endosymbiont of the African tick Amblyomma nuttalli is reported and Gene content comparison allows to infer that the ancestor could be reminiscent of C. burnetii, which could have been a major driver of such reductive evolution of the genus. Expand
Phylogenetics of the Spiroplasma ixodetis endosymbiont reveals past transfers between ticks and other arthropods.
TLDR
It is identified that ticks harbor a substantial diversity of divergent S. ixodetis strains, which strongly suggests that maternal inheritance and horizontal transfers are key drivers of S. _ixodentis spread, dictating global incidence of infections across tick communities. Expand
Maternally inherited symbiotic bacteria in ticks: incidence and biological importance
TLDR
A comprehensive view of symbionts in ticks is overviewed to help understand tick-symbiont associations, and may help to develop new strategies to control ticks and tick-borne diseases. Expand
Bacterial symbionts in human blood-feeding arthropods: Patterns, general mechanisms and effects of global ecological changes.
TLDR
The main mechanisms underlying bacterium-arthropod symbiosis are discussed, highlighting that even primary symbionts elicit an immune response from the host and the effects climate change, great human migrations, and the increasingly frequent interactions of wild and domestic animal species are analyzed. Expand
A Coxiella mutualist symbiont is essential to the development of Rhipicephalus microplus
The cattle tick Rhipicephalus microplus is a hematophagous ectoparasite that causes important economic losses in livestock. Different species of ticks harbor a symbiont bacterium of the genusExpand
Coxiella burnetii and Related Tick Endosymbionts Evolved from Pathogenic Ancestors
TLDR
Several metabolic pathways, including heme biosynthesis, are identified that are likely critical to the intracellular growth of the human pathogen but not the tick symbiont, and show that the use of heme analog is a promising approach to controlling C. burnetii infections. Expand
Multi-locus phylogenetics of the Midichloria endosymbionts reveals variable specificity of association with ticks
TLDR
Overall, two distinct evolutionary strategies are obvious depending on lineage: two Midichloria lineages are generalists with infections acquired through horizontal transfers between distantly related tick species but one other MidICHloria lineage rather show a high specificity degree to the Ixodes tick genus.

Evolutionary origin of insect–Wolbachia nutritional mutualism
TLDR
It is suggested that acquisition of a single gene cluster consisting of biotin synthesis genes underlies the bedbug–Wolbachia nutritional mutualism, uncovering an evolutionary transition from facultative symbiosis to obligate mutualism facilitated by lateral gene transfer in the endosymbiont lineage.

Arsenophonus, an emerging clade of intracellular symbionts with a broad host distribution
TLDR
The sample of currently available molecular data presents the genus Arsenophonus as one of the richest and most widespread clusters of insect symbiotic bacteria and its phylogenetic lineages indicates a complex evolution and apparent ecological versatility with switches between entirely different life styles.

Symbiosis and Insect Diversification: an Ancient Symbiont of Sap-Feeding Insects from the Bacterial Phylum Bacteroidetes
TLDR
It is shown that the large group of related insects including cicadas, leafhoppers, treehopper, spittlebugs, and planthoppers host a distinct clade of bacterial symbionts, belonging to the phylum Bacteroidetes. Expand
Symbiosis and Insect Diversification : an Ancient Symbiont of Sap-Feeding Insects from the Bacterial Phylum Bacteroidetes
Several insect groups have obligate, vertically transmitted bacterial symbionts that provision hosts with nutrients that are limiting in the diet. Some of these bacteria have been shown to descendExpand
Facultative symbionts in aphids and the horizontal transfer of ecologically important traits.
TLDR
Experiments on pea aphids have demonstrated that facultative symbionts protect against entomopathogenic fungi and parasitoid wasps, ameliorate the detrimental effects of heat, and influence host plant suitability. Expand
Evolution and diversity of Rickettsia bacteria
TLDR
It is shown that Rickettsia are primarily arthropod-associated bacteria, and several novel groups within the genus are identified, and multi-gene analysis indicates that different parts of the genome tend to share the same phylogeny. Expand
Evolution and diversity of Arsenophonus endosymbionts in aphids
TLDR
The diversity pattern of Arseno‐phonus strains in aphid populations from 86 species strongly suggests that ecological interactions, such as plant mediation and parasitism, are major drivers for Arsenophonus dispersal, dictating global incidence across insect communities. Expand
Microbial communities and interactions in the lone star tick, Amblyomma americanum
TLDR
The findings indicate that microbial communities within lone star ticks are diverse, and suggest that direct probing for a wider range of prokaryotes and application of quantitative polymerase chain reaction (PCR) may provide further insights into microbial interactions within disease vectors.

Specialization and Geographic Isolation Among Wolbachia Symbionts from Ants and Lycaenid Butterflies
TLDR
It is concluded that both geographic and phylogenetic barriers have promoted evolutionary divergence among these influential symbionts, providing the broadest and strongest evidence to date for Wolbachia specialization. Expand
Interspecific transmission of a male-killing bacterium on an ecological timescale.
TLDR
It is demonstrated experimentally that horizontal transfer of the son-killer infection of Nasonia wasps occurs readily following multi-parasitism events, and that the single host-single symbiont framework is insufficient for understanding the population and evolutionary dynamics in this system.
