In the present study, we observed that M. avidus not only escaped from the agglutinated mass but also conducted division(s) before shedding its old covering. Furthermore, ciliates that survived the antibody-dependent complement killing (ADCK) assay were not killed even when re-exposed to a freshly prepared ADCK assay. This result suggests that the liberated ciliates from the ADCK assay might change not only their i-antigen types but also the epitopes of major surface antigens, which debilitate antibody-mediated complement killing ability.

Gublin 1National Institute of Water and Atmospheric Research (NIWA), Private Bag 14901, Wellington, New Zealand 2NIWA, Station Road, Ruakaka, Northland 0166, New Zealand ABSTRACT: Ciliates associated with fish mortalities in a New Zealand hatchery were identified by DNA sequencing of the small subunit ribosomal RNA gene (SSU rRNA). Tissue samples were taken from lesions and gill tissues on freshly dead juvenile groper, brain tissue from adult kingfish, and from ciliate cultures and rotifers derived from fish mortality events between January 2007 and March 2009. Different mortality events were characterized by either of 2 ciliate species, Uronema marinum and Miamiensis avidus. A third ciliate, Mesanophrys carcini, was identified in rotifers used as food for fish larvae. Sequencing part of the SSU rRNA provided a rapid tool for the identification and mon- itoring of scuticociliates in the hatchery and allowed the first identification of these species in farmed fish in New Zealand.

Miamiensis Avidus
Parasitology Research https://doi.org/10.1007/s00436-018-6010-8 ORIGINAL PAPER Development of a safe antiparasitic against scuticociliates (Miamiensis avidus) in olive flounders: new approach to reduce the toxicity of mebendazole by material remediation technology using full-overlapped gravitational field energy Jung-Soo Seo1 & Na-Young Kim2 & Eun-Ji Jeon2 & Nam-Sil Lee2 & En-Hye Lee3 & Myoung-Sug Kim2 & Hak-Je Kim4 & Sung-Hee Jung2 Received: 5 March 2018 /Accepted: 6 July 2018 # The Author(s) 2018 Abstract The olive flounder (Paralychthys olivaceus) is a representative farmed fish species in South Korea, which is cultured in land-based tanks and accounts for approximately 50% of total fish farming production. However, farmed olive flounder are susceptible to infection with parasitic scuticociliates, which cause scuticociliatosis, a disease resulting in severe economic losses. Thus, there has been a longstanding imperative to develop a highly stable and effective antiparasitic drug that can be rapidly administered, both orally and by bath, upon infection with scuticociliates. Although the efficacy of commercially available mebendazole (MBZ) has previously been established, this compound cannot be used for olive flounder due to hematological, biochemical, and histopathological side effects. Thus, we produced material remediated mebendazole (MR MBZ), in which elements comprising the molecule wereARTICLE remediated by using full-overlapped grav- itational field energy, thereby reducing the toxicity of the parent material. The antiparasitic effect of MR MBZ against scuticociliates in olive flounder was either similar to or higher than that of MBZ under the same conditions. Oral (100 and500mg/kgB.W.)andbath(100and500mg/L) administrations of MBZ significantly (p < 0.05) increased the values of hematological and biochemical parameters, whereas these values showed no increase in the MR MBZ administration group. -

Extracellular Proteinases of Miamiensis Avidus Causing Scuticociliatosis Are Potential Virulence Factors

The virulence factors of the parasite have not been identified, so far. In this study, we examined M. avidus extracellular proteinases (ECPs) as potential virulence factors, using culture supernatants as an ECPs source. We investigated the substrate specificity of ECPs using artificial peptides, and the cytotoxicity of the ECPs was examined using CHSE-214 cells. To elucidate the role of ECPs in ciliate growth, M. avidus was cultured on CHSE-214 cells in the presence of proteinase inhibitors. We detected proteinase activities from the supernatant of M. avidus. Viable CHSE-214 cells decreased significantly in number, when incubated in a medium supplemented with the culture supernatant of M. avidus. The growth of ciliates on CHSE-214 cells was delayed in the presence of PMSF (serine pro- teinase inhibitor) and E-64 (cysteine proteinase inhibitor). These results suggested that the culture supernatant contained ECPs showing cytotoxicity, and the proteinases facilitated nutrient uptake by the ciliates. -
Miamiensis Avidus (Ciliophora: Scuticociliatida) Causes Systemic
DISEASES OF AQUATIC ORGANISMS Vol. 73: 227–234, 2007 Published January 18 Dis Aquat Org Miamiensis avidus (Ciliophora: Scuticociliatida) causes systemic infection of olive flounder Paralichthys olivaceus and is a senior synonym of Philasterides dicentrarchi Sung-Ju Jung*, Shin-Ichi Kitamura, Jun-Young Song, Myung-Joo Oh Department of Aqualife Medicine, Chonnam National University, Chonnam 550-749, Korea ABSTRACT: The scuticociliate Miamiensis avidus was isolated from olive flounder Paralichthys oli- vaceus showing typical symptoms of ulceration and hemorrhages in skeletal muscle and fins. In an infection experiment, olive flounder (mean length: 14.9 cm; mean weight: 26.8 g) were immersion challenged with 2.0 × 103, 2.0 × 104 and 2.0 × 105 ciliates ml–1 of the cloned YS1 strain of M. avidus. Cumulative mortalities were 85% in the 2.0 × 103 cells ml–1 treatment group and 100% in the other 2 infection groups. Many ciliates, containing red blood cells in the cytoplasm, were observed in the gills, skeletal muscle, skin, fins and brains of infected fish, which showed accompanying hemorrhagic and necrotic lesions. Ciliates were also observed in the lamina propria of the digestive tract, pharynx and cornea. The fixed ciliates were 31.5 ± 3.87 µm in length and 18.5 ± 3.04 µm in width, and were ovoid and slightly elongated in shape, with a pointed anterior and a rounded posterior, presenting a caudal cilium. Other morphological characteristics were as follows: 13 to 14 somatic kineties, oral cil- iature comprising membranelles M1, M2, M3, and paroral membranes PM1 and PM2, contractile vacuole at the posterior end of kinety 2, shortened last somatic kinety and a buccal field to body length ratio of 0.47 ± 0.03. -

Effect of Hyposalinity on the Infection and Pathogenicity of Miamiensis Avidus Causing Scutic- Ociliatosis in Olive Flounder Paralichthys Olivaceus

This suggests that hyposaline conditions can promote the development of the dis- ease. In the present study, olive flounder constantly showed high mortalities when they were exper- imentally challenged with the parasite by immersion and subsequently reared in hyposaline condi- tions. Furthermore, affected flounder produced by the challenge showed symptoms identical to those in naturally infected flounder. It was experimentally demonstrated that hyposaline conditions can be a key factor for the development and outbreak of scuticociliatosis in olive flounder.

In order to avoid the limitations of single gene/genome trees and to add more data to systematic COI analyses, information from mitochondrial DNA sequence has been increasingly used in different lineages of mtSSU-rDNA ciliates. The systematic relationships in the subclass Scuticociliatia are extremely confused and largely un- nSSU-rDNA resolved based on nuclear genes. In the present study, we have characterized 72 new sequences, including 40 Phylogeny mitochondrial cytochrome oxidase c subunit I (COI) sequences, 29 mitochondrial small subunit ribosomal DNA Secondary structure (mtSSU-rDNA) sequences and three nuclear small subunit ribosomal DNA (nSSU-rDNA) sequences from 47 isolates of 44 morphospecies.
