摘要：

Two recent 18S ribosomal RNA-based surveys of protist diversity near hydrothermal vents in the Pacific and Atlantic oceans allowed the identification of a variety of sequences related to several parasitic protist lineages. These include the Apicomplexa, Perkinsozoa, Syndiniales and Kinetoplastida. This diversity of parasitic protists could be hosted by the dense animal populations that thrive around these hydrothermal vents which contrasts with the scarcely populated cold deep-sea waters. These protist parasites might explain some of the mysterious sudden mortality episodes affecting the hydrothermal vent fauna.
