Stable associations of more than one species of symbiont within a single host cell or tissue are assumed to be rare in metazoans because competition for space and resources between symbionts can be detrimental to the host. In animals with multiple endosymbionts, such as mussels from deep-sea hydrothermal vents and reef-building corals, the costs of competition between the symbionts are outweighed by the ecological and physiological flexibility gained by the hosts. A further option for the… Expand

Symbiosis insights through metagenomic analysis of a microbial consortium.
TLDR
A metagenomic approach is used to describe four co-occurring symbionts from the marine oligochaete Olavius algarvensis, a worm lacking a mouth, gut and nephridia to propose a model that describes how the versatile metabolism within this symbiotic consortium provides the host with an optimal energy supply as it shuttles between the upper oxic and lower anoxic coastal sediments that it inhabits.

Multiple bacterial symbionts in two species of co-occurring gutless oligochaete worms from Mediterranean sea grass sediments.
TLDR
The phylogenetic and metabolic similarity of the symbiotic communities in these two co-occurring host species that are not closely related to each other indicates that syntrophic sulfur cycling provides a strong selective advantage to these worms in their sulfide-poor environment. Expand
Marine Chemosynthetic Symbioses
Bacteria and marine eukaryotes often coexist in symbioses that significantly influence the ecology, physiology and evolution of both partners. De Bary (1879) defined symbiosis as “the living togetherExpand
Metaproteomics of a gutless marine worm and its symbiotic microbial community reveal unusual pathways for carbon and energy use
TLDR
The high expression of proteins involved in pathways for energy and carbon uptake and conservation in the O. algarvensis symbiosis indicates that the oligotrophic nature of its environment exerted a strong selective pressure in shaping these associations. Expand
Interspecific evolution: microbial symbiosis, endosymbiosis and gene transfer.
Microbial symbioses are interesting in their own right and also serve as exemplary models to help biologists to understand two important symbioses in the evolutionary past of eukaryotic cells: theExpand
Phylogenetic and functional characterization of symbiotic bacteria in gutless marine worms (Annelida, Oligochaeta)
TLDR
The high phylogenetic diversity of bacterial endosymbionts in 2 species of the genus Inanidrilus shows that the stable coexistence of multiple symbionts is a common feature in gutless oligochaetes. Expand
Chemosynthetic endosymbioses: adaptations to oxic-anoxic interfaces.
TLDR
Recent studies of endosymbiont biology are reviewed, with emphasis on a conceptual model of thioautotrophic metabolism and studies linking symbiont physiology with the geochemical environment. Expand
Coexistence of Bacterial Sulfide Oxidizers, Sulfate Reducers, and Spirochetes in a Gutless Worm (Oligochaeta) from the Peru Margin
TLDR
A phylogenetically diverse yet highly specific and stable association in which multiple bacterial phylotypes coexist within a single host has not been described previously for marine invertebrates. Expand
Genome Reduction and Microbe-Host Interactions Drive Adaptation of a Sulfur-Oxidizing Bacterium Associated with a Cold Seep Sponge
TLDR
The results demonstrate that both this sponge symbiont and endosymbionts in deep-sea clams employ similar strategies of genome reduction, and suggest that microbes play different roles in biochemical cycles in the sponge body. Expand

Regulation of gutless annelid ecology by endosymbiotic bacteria
TLDR
It appears that the distributional and nutritional ecology of the gutless annelids is strongly influenced by their symbiosis with sulphur bacteria, coupling the needs of symbiont physiology with host behavioural ecology. Expand

TLDR
Using phylogenetic analysis, in situ hybridization, and denaturing gradient gel electrophoresis based on 16S ribosomal RNA genes, it is shown that in the gutless oligochete Olavius loisae, the 2 bacterial morphotypes correspond to 2 species of diverse phylogenetic origin. Expand

In phylogenetic trees inferred by both distance and parsimony methods, the oligochaete symbiont is peripherally associated with one of two clusters of chemoautotrophic symbionts that belong to the gamma subdivision of the Proteobacteria. Expand

Morphological and Ecophysiological Adaptations of the Marine Oligochaete Tubificoides benedii to Sulfidic Sediments
TLDR
Calculations on the diffusion rate of sulfide into T. benedii show that the deposition of ironsulfides do not play an important role in sulfide detoxification, and metabolic adaptations to hypoxia and sulfide include the maintenance of aerobic pathways despite low oxygen or high sulfide concentrations and the ability to gain energy through anaerobic pathways when oxygen and/or sulfide concentration become limiting.

The diversity of dissimilatory bisulfite reductase genes in the bacterial community on the back of the worm suggests a prominent role for anaerobic sulfate-reducing bacteria in the ecology of A. pompejana. Expand

TLDR
It is concluded that the high similarity of bacterial and archaeal DSRs reflects their common origin from a conserved DSR, which was either present before the split between the domains Bacteria, Archaea, and Eucarya or laterally transferred between Bacteria and Archaea soon after domain divergence.
