“…Several organisms have been implicated as the cause of this disease. In Japan, earlier investigators associated the disease (in both goldfish and coloured carp) with infection by an unidentified oomycete, Flexibacter {Chondroeoccus) columnaris or the ciliate Epistylis longicorpa (Miyazaki & Egusa 1973;Sejima, Morioka, Kanai, Hosoya & Suzuki 1973). Although the ulcerative disease is still prevalent in Japan, the oomycete and Epistylis are now rarely detected in cases of the disease (Takahashi, Kawana & Nakamura 1975a).…”

A comparative diagnostic study was conducted on goldfish, Carassius auratus (L.), with a cutaneous ulcerative disease from five locations in the United States and one each in England and Japan. Fish were examined for parasites, viruses and bacteria. Fish from all locations examined were infested by ectoparasites; no single parasite species was common to all locations. No virus-associated cj^opath-ology was observed in fathead minnow (FHM) or adult goldfish (CAR) monolayer cell cultures inoculated with homogenates of cutaneous lesions, kidneys and livers from diseased fish. The only bacterium cultured from fish from all locations was an atypical, often late-pigmenting strain of Aeromonas salmonicida. This organism was isolated from 64 of 83 (77%) of the total lesions cultured and was most prevalent in early lesions. A second commonly isolated organism was Aeromonas hydrophila, which was cultured from fish at four of the seven locations and from 28 (34%) of the total lesions cultured. A. hydrophila was most prevalent in terminal lesions. From these studies it was concluded that A. salmonicida was the probable cause of ulcers noted In the cases examined and that A. hydrophila was a secondary invader.

“…In Japan, studies on Epistylis species have mainly focused on fish pathology (e.g., Miyazaki and Egusa 1973;Sejima et al 1973) and their role as indicators for quantifying various properties of activated sludge in water treatment (e.g., Morishita 1964Morishita , 1968Morishita et al 2006). The diversity of free-living species of Epistylis in activated sludge has been well-documented by Morishita (1964Morishita ( , 1968 and Morishita et al (2006), with 22 species listed.…”

First Japanese Record of Epistylis wuhanensis (Ciliophora: Epistylididae) Attached to Lernaea cyprinacea (Copepoda), with a List of Epistylis Species Attached to Metazoans in Japan

The epistylidid ciliate Epistylis wuhanensis Wang, Zhou, Guo, and Gu, 2017 was found attached to the body surface of Lernaea cyprinacea Linnaeus, 1758 (Copepoda: Lernaeidae) parasitizing Rhinogobius similis Gill, 1859 (Perciformes: Gobiidae) from the Arida River in Wakayama Prefecture, Japan. This epistylidid was described based on live ciliates, stained specimens, and scanning electron microscope observation with molecular information. This is the first record of E. wuhanensis from Japan and the second record of the epistylidid attached to metazoans. A list of records of Epistylis Ehrenberg, 1830 species attached to metazoans in Japan is proposed.
