Abstract: | Female cuttlefish harbour a dense bacterial community in their accessory nidamental glands (ANG), as is also the case for
the myopsid squids. Molecular approaches have been applied to explore this symbiotic association in the sepiid species Sepia officinalis. In situ localisation by Bacteria-specific probes in tissue sections of the ANG revealed the presence of a dense bacterial population in the lumina of the
organ tubules. The phylogenetic identification of bacterial strains was realised by 16S rRNA gene sequencing analysis. None
of the sequences obtained matched perfectly with known sequences in the database. However their similarity percentages allowed
us to relate them to various bacterial groups including the taxa Agrobacterium, Roseobacter, Sporichthya, Rhodobium–Xanthobacter and Clostridium. Some bacterial species are common to both sepioids and myopsid teuthoids, others are different.
