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

This paper identifies and characterizes new genomes of Candidatus Megaira, revealing their hyperdiversity and potential for defensive symbiosis with algae and ciliates.

Isolation, culture and characterization of Arsenophonus symbionts from two insect species reveal loss of infectious transmission and extended host range in the apicola-nasoniae group.

Culture and genomic analysis of Arsenophonus apicola sp. nov. isolated from the honeybee Apis mellifera

The paper isolates and characterizes a new Arsenophonus species from honeybees, describes its genome, and proposes a new species name.

Culture and genomic analysis of Symbiopectobacterium purcellii, gen.nov. sp. nov., isolated from the leafhopper Empoasca decipiens

This paper describes the isolation and genomic analysis of a new bacterial symbiont, Symbiopectobacterium purcellii, from the leafhopper Empoasca decipiens, highlighting its unique genomic features and metabolic capabilities.

Large-scale comparative genomics unravels great genomic diversity across the Rickettsia and Ca. Megaira genera and identifies Torix group as an evolutionarily distinct clade.

This paper presents new genomes of Rickettsia and Ca. Megaira, identifies Torix as a distinct clade, and proposes a new genus name for it.

Structure of an ant-myrmecophile-microbe community

The paper characterizes the microbiota of ant-myrmecophile systems, finding that microbial communities reflect behavioral interactions and evolve independently of deep evolutionary history.

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

The paper screens 337 Culicoides individuals for Cardinium infection and identifies candidate species for studying symbiont interactions.

Cardinium symbiosis as a potential confounder of mtDNA based phylogeographic inference in Culicoides imicola (Diptera: Ceratopogonidae), a vector of veterinary viruses

This study shows that Cardinium symbiosis can affect mtDNA-based phylogeographic analysis in Culicoides imicola, suggesting the need for additional markers to accurately infer population movement.

Transitions in symbiosis: evidence for environmental acquisition and social transmission within a clade of heritable symbionts

This study shows that Arsenophonus symbionts in honey bees are acquired through environmental exposure and social transmission, not just vertical inheritance.

The Paracaedibacter-like endosymbiont of Bodo saltans (Kinetoplastida) uses multiple putative toxin-antitoxin systems to maintain its host association

This study identifies a Paracaedibacter-like endosymbiont in Bodo saltans that uses toxin-antitoxin systems to maintain host association, leading to cell death when the endosymbiont is removed.

The Tissue Tropisms and Transstadial Transmission of a Rickettsia Endosymbiont in the Highland Midge, Culicoides impunctatus (Diptera: Ceratopogonidae)

This study identifies tissue tropisms and transstadial transmission of Torix Rickettsia in Culicoides impunctatus, suggesting novel germline targeting and potential impacts on vector capacity.

Rapid molecular evolution of Spiroplasma symbionts of Drosophila

This study examines the rapid molecular evolution of Spiroplasma poulsonii, showing high substitution rates and structural genomic differences between strains.
