“…The Antarctic specimens of P. mutabilis (in vivo 32-50/im long) correspond rather well to those from more temperate regions (Foissner 1981;Song and Wilbert 1989;Blatterer and Foissner 1992). However, they have slightly fewer oral basket rods (about 12-14 vs about 15) and a more regular dorsal hump (vs irregularly folded).…”

The morphology of seven soil ciliate species from continental Antarctica was investigated using live observation and protargol impregnation. Observations on two populations of Protospathidium serpens corroborate the view that this species usually has a single, more-or-less nodular, macronucleus distinguishing it from P. muscicola, which possesses 10-30 nodules. The Antarctic specimens of Protospathidium terricola differ inconspicuously from the type population in that they are slightly larger, have fewer ciliary rows (17 vs 21), and the fragments of the circumoral kinety are less distinctly separated from each other. Spathidium seppelti nov. spec, resembles 5. bavariense, but has 100-200 macronuclear nodules and a conical depression in the dorsal third of the oral bulge. Odontochlamys wisconsinensis nov. comb, (basionym: Chilodonella wisconsinensis Kahl, 1931) has four right field kineties and an oral basket consisting of 14 rods; the dorsal brush is near the anterior margin and usually consists of four cilia. The Antarctic population of Pseudochilodonopsis mutabilis possesses a regular dorsal hump and only 12-14 (about 15 in Austrian type population) phary ngeal rods. Oxytricha opisthomuscorum has six dorsal kineties with long cilia and a buccal cirrus near the anterior end of the paroral membrane. The Antarctic specimens of Sterkiella histriomuscorum have five transverse cirri. Their morphogenesis differs slightly from that of a population having four transverse cirri in that the daughter's anlagen are more distinctly separated and some temporal sequences are different.

“…have a voracious appetite for living cells. A specialized mouth organ, the cytostome, is used to graze on bacteria, diatoms, filamentous green algae and cyanobacteria present on biofilm substrates of fish gills and skin (Foissner 1988;Blatterer & Foissner 1992;Dopheide et al 2011). The cytostome directly penetrates fish epithelial cells, allowing uptake of the contents (Paperna & Van As 1983;Wiles, Cone & Odense 1985;Noga 2010).…”

Current status of parasitic ciliates Chilodonella spp. (Phyllopharyngea: Chilodonellidae) in freshwater fish aquaculture

Freshwater fish farming contributes to more than two-thirds of global aquaculture production. Parasitic ciliates are one of the largest causes of production loss in freshwater farmed fishes, with species from the genus Chilodonella being particularly problematic. While Chilodonella spp. include 'free-living' fauna, some species are involved in mortality events of fish, particularly in high-density aquaculture. Indeed, chilodonellosis causes major productivity losses in over 16 species of farmed freshwater fishes in more than 14 countries. Traditionally, Chilodonella species are identified based on morphological features; however, the genus comprises yet uncharacterized cryptic species, which indicates the necessity for molecular diagnostic methods. This review synthesizes current knowledge on the biology, ecology and geographic distribution of harmful Chilodonella spp. and examines pathological signs, diagnostic methods and treatments. Recent advances in molecular diagnostics and the ability to culture Chilodonella spp. in vitro will enable the development of preventative management practices and sustained freshwater fish aquaculture production.
