Coolia monotis and Ostreopsis ovata are armoured, marine, benthic dinoflagellate
species. In tropical and subtropical seas, these dinoflagellates were among the
genera found in ciguatera affected areas. Generally, ciguatera fish poisoning is
associated with tropical reef fish, especially demersal herbivorous and
carnivorous fish of coral reefs and pelagic carnivores, such as mackerels and
barracudas. When organisms are rapidly exposed to high
concentrations of these toxic blooms, shellfish-poisoning events, significant
public health problems, and mass mortalities of aquatic organisms can result.
This marine algal
toxicity is very much related to the associated bacterial assemblages.
These samples were directly extracted from the clonal culture of these
dinoflagellates. With the long-term aim of understanding the role
of bacterial flora has in bloom development and toxicity of these benthic
dinoflagellates, we access the phylogenetic diversity of associated bacterial
assemblages using genomic-based approach.
In addition, a fosmid library of the same environmental samples had been
constructed to explore the distribution and diversity of metabolic pathways in
these communities.
