AB  - Priapulus caudatus (phylum Priapulida) is a benthic marine predatory worm with a 
      cosmopolitan distribution. In its digestive tract we detected symbiotic bacteria 
      that were consistently present in specimens collected over 8 years from three 
      sites at the Swedish west coast. Based on their 16S rRNA gene sequence, these 
      symbionts comprise a novel genus of the order Rickettsiales 
      (Alphaproteobacteria). Electron microscopy and fluorescence in situ hybridization 
      (FISH) identified them as extracellular, elongate bacteria closely associated 
      with the microvilli, for which we propose the name "Candidatus Tenuibacter 
      priapulorum". Within Rickettsiales, they form a phylogenetically well-defined, 
      family-level clade with uncultured symbionts of marine, terrestrial, and 
      freshwater arthropods. Cand. Tenuibacter priapulorum expands the host range of 
      this candidate family from Arthropoda to the entire Ecdysozoa, which may indicate 
      an evolutionary adaptation of this bacterial group to the microvilli-lined guts 
      of the Ecdysozoa.
