A Novel Lineage of Endosymbiotic Actinomycetales: Genome Reduction and Acquisition of New Functions in Bifidobacteriaceae Associated With Termite Gut Flagellates

open access: yesEnvironmental Microbiology, Volume 27, Issue 1, January 2025.
We have characterised several novel genera of Bifidobacteriaceae that colonise the cytoplasm of cellulolytic flagellates. Horizontal gene transfer played an important role in their adaptation to the intracellular environment. However, progressive genome erosion led to the loss of biosynthetic capacities that formed the basis of an originally ...

Potential Functions of the Gut Microbiome and Modulation Strategies for Improving Aquatic Animal Growth

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT The increase in the body weight of animals, a pivotal indicator closely tied to production, is important to the aquaculture industry. Despite remarkable variability in gut microbiomes, which are intricately associated with their hosts and affect overall performance, fitness, and physiological outcomes, across individuals and species, the ...

Identification of Spiroplasma insolitum symbionts in Anopheles gambiae [version 1; referees: 2 approved, 1 not approved]

open access: yesWellcome Open Research, 2017
Background: Insect symbionts have the potential to block the transmission of vector-borne diseases by their hosts. The advancement of a symbiont-based transmission blocking strategy for malaria requires the identification and study of Anopheles symbionts.

Transformation of the Drosophila Sex-Manipulative Endosymbiont Spiroplasma poulsonii and Persisting Hurdles for Functional Genetic Studies

open access: yesApplied and Environmental Microbiology, 2020
Dozens of bacterial endosymbiont species have been described and estimated to infect about half of all insect species. However, only a few them are tractable in vitro, which hampers our understanding of the bacterial determinants of the host-symbiont ...

Ticks From Mink and Their Associated Microorganisms in Spain

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Wildlife is an important source of emerging zoonotic agents, including tick‐borne ones. Wild carnivores such as mink are commonly parasitized by ticks, which are vectors and reservoirs of zoonotic diseases. Besides the importance of these arthropods as potential sources of diseases in mink, and the role of these mammals as reservoirs of infectious ...

Phylogenetic origin and sequence features of MreB from the wall-less swimming bacteria Spiroplasma

open access: yesbioRxiv, 2020
Spiroplasma are wall-less bacteria which belong to the phylum Tenericutes that evolved from Firmicutes including Bacillus subtilis. Spiroplasma swim by a mechanism unrelated to widespread bacterial motilities, such as flagellar motility, and caused by ...

Sex‐biased gene content is associated with sex chromosome turnover in Danaini butterflies

open access: yesMolecular Ecology, Volume 33, Issue 24, December 2024.
Abstract Sex chromosomes play an outsized role in adaptation and speciation, and thus deserve particular attention in evolutionary genomics. In particular, fusions between sex chromosomes and autosomes can produce neo‐sex chromosomes, which offer important insights into the evolutionary dynamics of sex chromosomes. Here, we investigate the evolutionary

Disseminated Spiroplasma apis Infection in Patient with Agammaglobulinemia, France

open access: yesEmerging Infectious Diseases, 2018
We report a disseminated infection caused by Spiroplasma apis, a honeybee pathogen, in a patient in France who had X-linked agammaglobulinemia. Identification was challenging because initial bacterial cultures and direct examination by Gram staining were

Evolutionary costs and benefits of infection with diverse strains of Spiroplasma in pea aphids *

open access: yesEvolution; international journal of organic evolution, 2019
The heritable endosymbiont Spiroplasma infects many insects and has repeatedly evolved the ability to protect its hosts against different parasites. Defenses do not come for free to the host, and theory predicts that more costly symbionts need to provide

Generality of toxins in defensive symbiosis: Ribosome-inactivating proteins and defense against parasitic wasps in Drosophila.

open access: yesPLoS Pathogens, 2017
While it has become increasingly clear that multicellular organisms often harbor microbial symbionts that protect their hosts against natural enemies, the mechanistic underpinnings underlying most defensive symbioses are largely unknown.
