Taxonomic re-assignment of Cryptocaryon irritans, a marine fish parasite
European Journal of Protistology, 2002Cryptocaryon irritans, a ciliated protozoan, is one of the most devastating parasites of marine fish cultured in temperate and tropical seas. Based on the remarkable affinities with its “freshwater counterpart” Ichthyophthirius multifiliis, C. irritans has traditionally been included in the Ichthyophthiriidae, although cytological studies failed to ...

Influence of Temperature and Host Species on the Development of Cryptocaryon irritans
The Journal of Parasitology, 1996The course of infection of the parasitic ciliate Cryptocaryon irritans was followed on Lates calcarifer and Macquaria novemaculeata at 20 and 25 C. The parasite was originally isolated from locally caught Acanthopagrus australis. At 20 C trophonts stayed on the fish longer, tomonts took longer to excyst, and the resulting theronts were larger than at ...

Food intake, survival, and immunity of Nibea albiflora to Cryptocaryon irritans infection
Parasitology Research, 2018Cultured Nibea albiflora rarely die from cryptocaryoniasis. To explore the resistance of N. albiflora against the invasion of Cryptocaryon irritans, in this study, 40 g N. albiflora was artificially infected with C. irritans at a median lethal concentration (2050 theronts/g fish).

In vitro and in vivo efficacies of ionophores against Cryptocaryon irritans
Aquaculture, 2011Abstract We assayed the effects of a variety of antiprotozoal compounds against trophonts of Cryptocaryon irritans , the causative agent of ‘white spot disease of marine fish’ in vitro using the double layered media that we developed previously for the culture of the parasite.

Transcriptomic analysis of Nibea albiflora skin in response to infection by Cryptocaryon irritans
Fish & Shellfish Immunology, 2020Massive infection caused by Cryptocaryon irritans is detrimental to the development of marine aquaculture. Recently, our lab found that Nibea albiflora has low sensitivity and low mortality to C. irritans infection. The present study was designed to investigate the mechanisms of the N. albiflora response to C.

A technique for the preservation of Cryptocaryon irritans at low temperatures
Aquaculture, 2009Abstract Applied and basic research to evaluate the ciliate Cryptocaryon irritans requires serial passage in fish hosts to maintain the laboratory stock. However, continual repeated passage is labour-intensive and time-consuming and results in the senescence of parasite clones over time.

Antiparasitic efficacy of honokiol against Cryptocaryon irritans in pompano, Trachinotus ovatus
Aquaculture, 2019Abstract Cryptocaryon irritans, a marine fish ectoparasite, causes mass economic loss in the mariculture and ornamental fish industries. It is important to find effective alternatives that may be both affordable and environmentally acceptable to control the damage of C. irritans.

AbstractCryptocaryonosis is a major problem for mariculture, and the absence of suitable sero‐surveillance tools for the detection of cryptocaryonosis makes it difficult to screen Cryptocaryon irritans‐infected fish, particularly asymptomatic fish. In this study, we proposed a serum‐based assay using selected C. irritans proteins to screen infected and

Functional role of TrIL-1β in Takifugu rubripes defense against Cryptocaryon irritans infection
International Journal of Biological MacromoleculesThe Japanese puffer, Takifugu rubripes, is a commercially important fish species in China that is under serious threat from white spot disease (cyptocaryoniasis), which leads to heavy economic losses. We previously found that interleukin-1β (IL-1β), an important cytokine with a potential role in resistance against pathogens, was one of the most ...
