Interpretive Summary: Members of the genus Arcobacter have been isolated from a wide range of hosts and environments. Arcobacter species are a common contaminant of food and food animals. However, arcobacters also inhabit freshwater and seawater environments and can infest shellfish, such as mussels, clams, oysters and abalone, through filter feeding. Thus, although the pathogenicity and toxicity of several Arcobacter species is currently undetermined, humans could be potentially exposed to Arcobacter through consumption of infested shellfish. Arcobacter molluscorum was isolated originally from mussels collected in the Ebro Delta in Catalonia, Spain. This study reports the first closed chromosomal sequence for the type strain of the species. Consistent with its growth in marine environments, A. molluscorum contains genes that confer tolerance to higher salt levels, as might be necessary for growth in seawater and shellfish. Additionally, this strain can synthesize vitamin B12 and possesses a number of signal transduction pathways that allow the organism to sense and respond to various metabolites and environmental conditions. A. molluscorum can also ‘fix’ nitrogen, that is, convert atmospheric nitrogen to ammonia, which can then be used by the organism.

Technical Abstract: As components of freshwater and marine microflora, Arcobacter spp. are often recovered from shellfish, such as mussels, clams and oysters. Arcobacter molluscorum was isolated from mussels of the Ebro Delta in Catalonia, Spain. This study describes the whole-genome sequence of the A. molluscorum strain LMG 25693T (=F98-3T =CECT 7696T).
