“…Examples include Ichthyophthirius multifiliis which is responsible for white spot disease in freshwater fishes (Abdel-Hafez et al, 2014;Forwood et al, 2014;Fu et al, 2014;Hoshino et al, 2014), and various species of scuticociliates that cause a range of diseases (collectively termed 'scuticociliatosis') in economically important host organisms Jin et al, 2010;Zhan et al, 2014).…”

“…Recent research has demonstrated these ciliates are emerging opportunistic pathogens for cultured aquatic animals (Jones, Prosperi‐Porta & LaPatra ; Zhan et al . ). Although morphological techniques are routinely used to identify scuticociliates, this methodology alone may have limitations as many scuticociliates species can exhibit similar morphology.…”

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.

“…Ciliates in the subclass Scuticociliatia, commonly found in ecosystems worldwide, exhibit a great biological diversity and play important roles in marine ecosystems (Thompson & Kaneshiro 1968;Foissner & Wilbert 1981;Cawthorn et al 1996;Lynn & Strüder-Kypke 2005;Fan et al 2011aFan et al , b, 2014Pan et al 2013a, b;Castro et al 2014;Foissner et al 2014;Zhan et al 2014). Many of them are common pathogens of fishes and invertebrates and can cause severe disease or even death in economically important aquaculture animals (Pérez-Uz & Song 1995;Song & Wilbert 2002;Fan et al 2009Mallo et al 2014;Ofelio et al 2014).…”

Generally, “ophrys- related” scuticociliates belong to a specialised group of ciliated protozoa that may act as commensals or pathogens of fishes and crustaceans. In the present study, four “ophrys- taxa” scuticociliates, i.e., Paramesanophrys typica gen. et sp. nov., Mesanophrys carcini (Grolière & Léglise, 1977) Small & Lynn in Aescht, 2001, Metanophrys sinensis Song & Wilbert, 2000, and Metanophrys similis Song et al., 2002, were collected from Chinese coastal waters or mariculture ponds and investigated. Paramesanophrys gen. nov. is assigned to the family Orchitophryidae and differs from its other genera mainly by the position of the paroral membrane relative to membranelle 1–3, i.e., the membrane extends anteriorly to the posterior end of membranelle 3. The type species P. typica gen. et sp. nov., is defined by an elongated body with the posterior end depressed where the caudal cilium is located; 20 or 21 somatic kineties; double-rowed membranelle 1 with eight to ten basal bodies in each kinety; irregularly multi-rowed membranelle 2 and membranelle 3; scutica comprising c. seven or eight kinetosome pairs; a single macronuclear nodule; and marine habitat. The redescription of the three previously known species can be summarized as follows: 1) improved diagnosis is provided for Metanophrys sinensis Song & Wilbert, 2000 based on the original description and the present study; 2) some population-dependent characteristics of our new Mesanophrys carcini isolate are presented; 3) Metanophrys similis, collected from the South China Sea, resembles the original Qingdao population.
