First description of giant Archaea (Thaumarchaeota) associated with putative bacterial ectosymbionts in a sulfidic marine habitat.
Archaea may be involved in global energy cycles, and are known for their ability to interact with eukaryotic species (sponges, corals and ascidians) or as archaeal-bacterial consortia. The recentlyExpand

Characterization of the Population of the Sulfur-Oxidizing Symbiont of Codakia orbicularis (Bivalvia, Lucinidae) by Single-Cell Analyses
ABSTRACT We investigated the characteristics of the sulfur-oxidizing symbiont hosted in the gills of Codakia orbicularis, a bivalve living in shallow marine tropical environments. Special attentionExpand

Detection of the Free-Living Forms of Sulfide-Oxidizing Gill Endosymbionts in the Lucinid Habitat (Thalassia testudinum Environment)
ABSTRACT Target DNA from the uncultivable Codakia orbicularis endosymbiont was PCR amplified from sea-grass sediment. To confirm that such amplifications originated from intact bacterial cells ratherExpand

Sulphur-oxidizing extracellular bacteria in the gills of Mytilidae associated with wood falls.
Six morphotypes of small mussels (Bivalvia: Mytilidae) were found attached to naturally sunken wood collected in the Bohol Sea (Philippines). These specimens are related to the large BathymodiolusExpand

Embryonic development and shell differentiation in Chione cancellata (Bivalvia, Veneridae): an ultrastructural analysis
. The embryonic development in Chione cancellata, from fertilization to straight-hinge D-stage veliger larva, occurs in 24 h at 25°C. Transmission (TEM) and scanning (SEM) electron microscopy showExpand

Interspecific infection of aposymbiotic juveniles of Codakiaorbicularis by various tropical lucinid gill-endosymbionts
Abstract. Previous molecular phylogenetic analyses have shown that five tropical lucinid species living in or near Thalassiatestudinum seagrass beds are colonized by the same bacterial symbiontExpand

Effects of Long-Term Starvation on a Host Bivalve (Codakia orbicularis, Lucinidae) and Its Symbiont Population
ABSTRACT The bivalve Codakia orbicularis, hosting sulfur-oxidizing gill endosymbionts, was starved (in artificial seawater filtered through a 0.22-μm-pore-size membrane) for a long-term experiment (4Expand

Environmental transmission of a sulfur-oxidizing bacterial gill endosymbiont in the tropical lucinid bivalve Codakia orbicularis.
Codakia orbicularis is a large tropical member of the bivalve mollusk family Lucinidae which inhabits shallow-water sea-grass beds (Thalassia testudinum environment) and harbors sulfur-oxidixingExpand
