Colliniidae is a family of ciliates of the order Apostomatida.
Krill(Euphausiids), are small and exclusively marine crustaceans of the order Euphausiacea, found in all the world's oceans. The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", which is also often attributed to species of fish.
The oligotrichs are a group of ciliates, included among the spirotrichs. They have prominent oral cilia, which are arranged as a collar and lapel, in contrast to the choreotrichs where they form a complete circle. The body cilia are reduced to a girdle and ventral cilia. In Halteria and its relatives, they form bristles or cirri; however these forms may be closer relatives of the stichotrichs than of other oligotrichs. These organisms are very common in plankton communities, especially in marine systems. Usually found in concentrations of about 1 per ml, they are the most important herbivores in the sea, the first link in the food chain.
Hematodinium perezi is a pathogenic dinoflagellate parasite that infects crustaceans, including the Blue Crab and Norway Lobster and has been observed to have a significant impact on crustacean fisheries. Infected crustaceans frequently show signs of weakness and lethargy, and often die due to stress-related handling from fishing as well as metabolic exhaustion due to reduced feeding. This parasite is known to be quite transmissible between various crustacean hosts.
Hematodinium is a genus of dinoflagellates. Species in this genus, such as Hematodinium perezi, the type species, are internal parasites of the hemolymph of crustaceans such as the Atlantic blue crab and Norway lobster. Species in the genus are economically damaging to commercial crab fisheries, including causing bitter crab disease in the large Tanner or snow crab fisheries of the Bering Sea.
Vibrio tapetis is a Gram-negative, rod-shaped bacterium, the causative agent of the brown ring disease that affects cultured clams. B1090 is the type strain.
Hyalophysa chattoni is an apostome ciliate of the order Apostomatida. The polymorphic symbiont is carried as an encysted phoront on the exoskeleton of few arthropods belonging to the subphylum Crustacea and undergoes metamorphosis during the host's premolt followed by various other life-cycle stages.
Pseudocollinia is a genus of parasitoid ciliate of the Colliniidae family.
Pseudocollinia brintoni is a species of parasitoid ciliates of the Colliniidae family. P. brintoni infects a species of krill, Nyctiphanes simplex.
Collinia is a genus of parasitoid ciliates of the Colliniidae family.
Collinia beringensis is a species of parasitoid ciliates of the Colliniidae family. It is an endoparasite of Thysanoessa inermis, a species of krill.
Collinia oregonensis is a species of parasitoid ciliates of the Colliniidae family. It is known to infect the krill Euphausia pacifica, Thysanoessa spinifera, and Thysanoessa gregaria off the coast of Oregon and Washington. It caused a mass mortality of E. pacifica in June 2001 at the base of Astoria Canyon.
Miamiensis avidus is a species of unicellular marine eukaryote that is a parasite of many different types of fish. It is one of several organisms known to cause the fish disease scuticociliatosis and is considered an economically significant pathogen of farmed fish. M. avidus is believed to be the cause of a 2017 die-off of fish and sharks in the San Francisco Bay.
Philasterides dicentrarchi is a marine protozoan ciliate that was first identified in 1995 after being isolated from infected European sea bass reared in France. The species was also identified as the causative agent of outbreaks of scuticociliatosis that occurred between summer 1999 and spring 2000 in turbot cultivated in the Atlantic Ocean. Infections caused by P. dicentrarchi have since been observed in turbot reared in both open flow and recirculating production systems. In addition, the ciliate has also been reported to cause infections in other flatfishes, such as the olive flounder in Korea and the fine flounder in Peru, as well as in seadragons, seahorses, and several species of sharks in other parts of the world.
Scuticociliatosis is a severe and often fatal parasitic infection of several groups of marine organisms. Species known to be susceptible include a broad range of teleosts, seahorses, sharks, and some crustaceans. The disease can be caused by any one of about 20 distinct species of unicellular eukaryotes known as scuticociliates, which are free-living marine microorganisms that are opportunistic or facultative parasites. Scuticociliatosis has been described in the wild, in captive animals in aquariums, and in aquaculture. It is best studied in fish species that are commonly farmed, in which typical effects of infection include skin ulceration, hemorrhage, and necrosis, with post-mortem examination identifying ciliates in the skin, gills, blood, and internal organs including the brain.
Viral gametocytic hypertrophy is a pathological condition observed in the Pacific oyster.
Endozoicomonas elysicola is a Gram-negative, rod-shaped and strictly aerobic bacterium from the genus of Endozoicomonas which has been isolated from the gastrointestinal tract of the sea slug Elysia ornata from the coast of Izu-Miyake Island in Japan.
Acipenserid herpesvirus 2 (AciHV-2) is a virus in the genus Ictalurivirus, family Alloherpesviridae, and order Herpesvirales. It infects sturgeon of the family Acipenseridae.
Salmonid herpesvirus 3 (SalHV-3) is a species of virus in the genus Salmonivirus, family Alloherpesviridae, and order Herpesvirales.
Philasterides is a genus of ciliates in the order Philasteridae.
Hennegoides is a genus of cnidarian that is part of the family Myxobolidae.
