Identification of a ciliate (Oligohymenophorea: Scuticociliatia) associated with brown band disease on corals of the great barrier reef

Abstract

A ciliate associated with the coral disease brown band (BrB) was identified as a new species belonging to the class Oligohymenophorea, subclass Scuticociliatia. The ciliates were characterized by the presence of large numbers of intracellular dinoflagellates and displayed an elongated, tube-shaped body structure. They had uniform ciliature, except for three distinct cilia in the caudal region, and were typically 200 to 400 μmm in length and 20 to 50 μm in width.
