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… 

Symbiosis insights through metagenomic analysis of a microbial consortium.

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.

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.

Marine Chemosynthetic Symbioses

This chapter describes such symbioses, specifically those between marine invertebrate and protist hosts and chemosynthetic bacterial symbionts, which cluster primarily within the Gammaproteobacteria.

Metaproteomics of a gutless marine worm and its symbiotic microbial community reveal unusual pathways for carbon and energy use

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.

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: the

Phylogenetic and functional characterization of symbiotic bacteria in gutless marine worms (Annelida, Oligochaeta)

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.

Coexistence of Bacterial Sulfide Oxidizers, Sulfate Reducers, and Spirochetes in a Gutless Worm (Oligochaeta) from the Peru Margin

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.

Genome Reduction and Microbe-Host Interactions Drive Adaptation of a Sulfur-Oxidizing Bacterium Associated with a Cold Seep Sponge

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.

Chemosynthetic symbiont with a drastically reduced genome serves as primary energy storage in the marine flatworm Paracatenula

Study of a species of Paracatenula from Sant’Andrea, Elba, Italy, using genomics, gene expression, imaging analyses, as well as targeted and untargeted MS, shows that its symbiont, Ca.

Regulation of gutless annelid ecology by endosymbiotic bacteria

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.

Phylogenetic diversity of bacterial endosymbionts in the gutless marine oligochete Olavius loisae (Annelida)

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.

Morphological and Ecophysiological Adaptations of the Marine Oligochaete Tubificoides benedii to Sulfidic Sediments

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.

Phylogeny of Dissimilatory Sulfite Reductases Supports an Early Origin of Sulfate Respiration

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.
