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… 

Microbial community structure reveals instability of nutritional symbiosis during the evolutionary radiation of Amblyomma ticks

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.

Ecological Contacts and Host Specificity Promote Replacement of Nutritional Endosymbionts in Ticks

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.

A dual endosymbiosis drives nutritional adaptation to hematophagy in the invasive tick Hyalomma marginatum

It is shown that the invasive tick Hyalomma marginatum harbors a unique dual-partner nutritional system between an ancestral symbiont, Francisella, and a more recently acquired symbionts, Midichloria, which is a key mechanism for advanced adaptation of arthropods to specialized diets.

A dual endosymbiosis supports nutritional adaptation to hematophagy in the invasive tick Hyalomma marginatum

It is evidence here that the invasive tick Hyalomma marginatum harbors a unique dual-partner nutritional system between an ancestral symbiont, Francisella, and a more recently acquired symbionts, Midichloria.

Sequence of a Coxiella Endosymbiont of the Tick Amblyomma nuttalli Suggests a Pattern of Convergent Genome Reduction in the Coxiella Genus

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.

Maternally inherited symbiotic bacteria in ticks: incidence and biological importance

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.

Genomic Changes During the Evolution of the Coxiella Genus Along the Parasitism-Mutualism Continuum

The Coxiellaceae family is composed of five genera showing lifestyles ranging from free-living to symbiosis. Among them, Coxiella burnetii is a well-known pathogen causing Q fever in humans. This

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 genus



Evolutionary origin of insect–Wolbachia nutritional mutualism

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

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

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.

Facultative symbionts in aphids and the horizontal transfer of ecologically important traits.

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.

Evolution and diversity of Rickettsia bacteria

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.

Evolution and diversity of Arsenophonus endosymbionts in aphids

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.

Microbial communities and interactions in the lone star tick, Amblyomma americanum

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

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.

Interspecific transmission of a male-killing bacterium on an ecological timescale.

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.

Diversification of endosymbiosis: replacements, co-speciation and promiscuity of bacteriocyte symbionts in weevils

The results suggest that the Sodalis-allied symbiont was certainly acquired by an ancestor of the Sitophilus weevils and replaced the original Nardonella symbionts, but the symbiotic association must have experienced occasional re-associations such as new acquisitions, horizontal transfers, replacements and/or losses.
