| Our knowledge of the viral diversity associated to microorganisms inhabiting the deep-sea hydrothermal vents is still limited. Only a few studies have focused on viral abundance and impact on microbial mortality within these ecosystems. A limited number of viruses (6 bacterioviruses and 2 archaeoviruses) were isolated from these environments and characterized. Two viruses associated to hyperthermophilic anaerobic Archaea, from the Thermococcales order, have been described in our laboratory. In order to deepen our knowledge on the viral diversity of these extreme environments, we have extended our investigation to the bacterial order of Thermotogales. This order is composed of anaerobic chemoorganotrophic bacteria that are, for the most part,... |
