- Abstract
- Luminous bacteria are isolated from both Hydrozoa
and Bryozoa with chitinous structures on their surfaces.
All the specimens of the examined hydroid species
(Aglaophenia kirchenpaueri, Aglaophenia octodonta,
Aglaophenia tubiformis, Halopteris diaphana, Plumularia
setacea, Ventromma halecioides), observed under blue light
excitation, showed a clear fluorescence on the external side
of the perisarc (chitinous exoskeleton) around hydrocladia.
In the bryozoan Myriapora truncata, luminous bacteria are
present on the chitinous opercula. All the isolated luminous
bacteria were identified on the basis of both phenotypic and
genotypic analysis. The isolates from A. tubiformis and H.
diaphana were unambiguously assigned to the species
Vibrio fischeri. In contrast, the isolates from the other
hydroids, phenotypically assigned to the species Vibrio
harveyi, were then split into two distinct species by
phylogenetic analysis of 16S rRNA gene sequences and
DNA-DNA hybridization experiments. Scanning electron
microscopy analysis and results of culture-based and
culture-independent approaches enabled us to establish
that luminous vibrios represent major constituents of the
bacterial community inhabiting the A. octodonta surface
suggesting that the interactions between luminous bacteria
and the examined hydrozoan and bryozoan species are
highly specific. These interactions might have epidemiological
as well as ecological implications because of the
opportunistic pathogenicity of luminous Vibrio species for
marine organisms and the wide-distribution of the hydrozoan
and bryozoan functioning as carriers. (literal)
