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.

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.

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

Findings reveal the importance of geographic, ecological, and phylogenetic proximity in shaping the replacement pattern in which new nutritional symbioses are initiated in tick communities driven by horizontal transfers.

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.

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.

Anti-tick microbiota vaccines: how can this actually work?

It is hypothesized that immune targeting of key members of the bacterial community of the tick microbiome by host antibodies could cause microbial dysbiosis with consequences for tick physiology and vector competence and the possibilities of this methodology for the control of ticks and tick-borne diseases are explored.

The Symbiotic Continuum Within Ticks: Opportunities for Disease Control

The widespread occurrence of endosymbionts across the tick phylogeny and evidence of their functional roles in ticks and interference with tick-borne pathogens suggests a significant contribution to tick evolution and/or vector competence.

What do we know about the microbiome of I. ricinus?

It is shown that endosymbionts including Coxiella-like spp.

Update on the intricate tango between tick microbiomes and tick‐borne pathogens

Ticks represent a compelling yet challenging system in which to investigate the composition and both the functional and ecological implications of tick bacterial communities, and thus merits greater attention, and how ticks and tick‐borne diseases might potentially be controlled through tick microbiome manipulation in the future is discussed.

Genome sequence of the endocellular obligate symbiont of tsetse flies, Wigglesworthia glossinidia

The complete annotated genome of Wigglesworthia glossinidia brevipalpis is presented, and surprisingly, this obligate's genome bears hallmarks of both parasitic and free-living microbes, and the gene encoding the important regulatory protein DnaA is absent.

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.

A Novel Human-Infection-Derived Bacterium Provides Insights into the Evolutionary Origins of Mutualistic Insect–Bacterial Symbioses

This study characterized a novel opportunistic human pathogen, designated “strain HS,” and found that it is a close relative of the insect endosymbiont Sodalis glossinidius, providing compelling support for the notion that mutualists evolve from pathogenic progenitors.

Insect life history and the evolution of bacterial mutualism.

It is found that aphid species that have mutualistic associations with ants that protect them from natural enemies are less likely to carry symbionts that provide similar benefits, and one symbiont species occurs more frequently in unrelated aphids that specialise on certain plant genera.

A Coxiella-Like Endosymbiont Is a Potential Vitamin Source for the Lone Star Tick

The CLEAA genome was sequenced and it was revealed that CLEAA is a close relative of C. burnetii, but was not derived from it, indicating that it is an essential endosymbiont of A. americanum.

Wolbachia as a bacteriocyte-associated nutritional mutualist

Results indicate that bacteriocyte-associated nutritional mutualism can evolve from facultative and prevalent microbial associates like Wolbachia, highlighting a previously unknown aspect of the parasitism-mutualism evolutionary continuum.

The Recent Evolution of a Maternally-Inherited Endosymbiont of Ticks Led to the Emergence of the Q Fever Pathogen, Coxiella burnetii

This corpus of data demonstrates that C. burnetii recently evolved from an inherited symbiont of ticks which succeeded in infecting vertebrate cells, likely by the acquisition of novel virulence factors.

Multiple Acquisitions of Pathogen-Derived Francisella Endosymbionts in Soft Ticks

It is shown that FLEs encode intact pathways for the production of several B vitamins and cofactors, denoting that they could function as nutrient-provisioning endosymbionts in ticks.

Evolutionary changes in symbiont community structure in ticks

Examination of 81 tick species shows that some Coxiella‐LE symbioses are evolutionarily stable with an ancient acquisition followed by codiversification as observed in ticks belonging to the Rhipicephalus genus, however, many other Coxiellas-LE symbionts are characterized by low evolutionary stability with frequent host shifts and extinction events.

A Francisella-like endosymbiont in the Gulf Coast tick evolved from a mammalian pathogen

The genome of an FLE, termed FLE-Am, present in the Gulf Coast tick, is sequenced and shown to have likely evolved from a pathogenic strain of Francisella, indicating that tick endosymbionts can evolve from mammalian pathogens.
