Invasive orchitophryid ciliate infections in juvenile Pacific and Kumomoto oysters, Crassostrea gigas and Crassostrea sikamea

Recruitment of the Pacific oyster Crassostrea gigas in a shellfish-exploited Mediterranean lagoon: discovery, driving factors and a favorable environmental window

“…Picoplankton also support grazing by ciliate and flagellate protists (Lam-Hoai et al 1997, Bec et al (Plunket & Hidu 1978, Elston et al 1999, Shimeta et al 2012. Our results support this hypothesis since a negative correlation was observed between the abundance of ciliates and the metamorphosis success of C. gigas.…”

Philasterides dicentrarchi (Ciliophora, Scuticociliatida) as the causative agent of scuticociliatosis in farmed turbot Scophthalmus maximus in Galicia (NW Spain)

“…However, most histophagous ciliates are free-living, and are typically scavengers that feed on suspended particulate matter (bacteria, microalgae, protozoa, etc.). Under certain circumstances, these ciliates may behave as facultative parasites, actively feeding on cells and tissue residues of certain molluscs (Elston et al 1999), crustaceans and fishes, and living and reproducing within the host tissues. As regards crustaceans, the scuticociliates Anophryoides haemophila and Mesanophrys spp.…”

Scuticociliatosis and its recent prophylactic measures in aquaculture with special reference to South Korea

“…Under certain circumstances, these ciliates may behave as facultative parasites, actively feeding on cells and tissues of certain other aquatic animals, such as crustaceans and molluscs [27,28] living and reproducing within the host tissues. As regards other species, scuticociliates like A. haemophila and Mesanophrys spp.…”
