Abstract
AbstractSymbiotic bacteria can alter host biology by providing protection from natural enemies, or alter reproduction or vectoral competence. Symbiont‐linked control of vector‐borne disease in Anopheles has been hampered by a lack of symbioses that can establish stable vertical transmission in the host. Previous screening found the symbiont ‘Candidatus Tisiphia’ in Anopheles plumbeus, an aggressive biter and potential secondary vector of malaria parasites and West Nile virus. We screened samples

'Candidatus Megaira' are diverse symbionts of algae and ciliates with the potential for defensive symbiosis

Abstract
Symbiotic microbes from the genus 'Candidatus Megaira' ( Rickettsiales ) are known to be common associates of algae and ciliates. However, genomic resources for these bacteria are scarce, limiting our understanding of their diversity and biology. We therefore utilize Sequence Read Archive and metagenomic assemblies to explore the diversity of this genus. We successfully extract four draft 'Ca. Megaira' genomes

Abstract
AbstractSymbiotic microbes from the genus ‘Candidatus Megaira’ (Rickettsiales) are known to be common associates of algae and ciliates. However genomic resources for these bacteria are scarce, limiting our understanding of their diversity and biology. We therefore utilized SRA and metagenomic assemblies to explore the diversity of this genus. We successfully extracted four draft ‘Ca. Megaira’ genomes including one complete scaffold for a ‘Ca. Megaira’ and identified an additional 14 draft genome

Abstract
AbstractMembers of the bacterial genusRickettsiawere originally identified as causative agents of vector-borne diseases in mammals. However, manyRickettsiaspecies are arthropod symbionts and close relatives of ‘CandidatusMegaira’, which are symbiotic associates of microeukaryotes. Here, we clarify the evolutionary relationships between these organisms by assembling 26 genomes ofRickettsiaspecies from understudied groups, including the Torix group, and two genomes of ‘Ca. Megaira’ from various in

Identifying candidate Culicoides spp. (Diptera: Ceratopogonidae) for the study of interactions with Candidatus Cardinium hertigii (Bacteroidetes)

Ca. Cardinium hertigii
Abstract
AbstractCulicoides biting midges (Diptera: Ceratopogonidae) are disease vectors responsible for the transmission of several viruses of economic and animal health importance. The recent deployment of Wolbachia with pathogen-blocking capacity to control viral disease transmission by mosquitoes has led to a focus on the potential use of endosymbionts to control arboviruses transmitted by other vector species. Previous screens of Culicoides have described the presence of Candidatus Cardinium hertigi
