Scuticociliates are dangerous parasitic pathogens causing systemic tissue destruction and high mortality in marine fish worldwide. In this study, the first identification of (Ciliophora, Scuticociliatida) from cultured turbot () larvae using mitochondrial cytochrome c oxidase 1 (1) gene sequence as well as species-specific primers was reported. The mean prevalence values of infected fish were calculated, and partial sequencing obtained from the mitochondrial 1 gene region was also compared with isolates registered in the Genbank database. The sequence comparison showed 93.00% identity to , and the parasite has also been deposited in the GenBank database. This study is the first case of infection in Turkish marine aquaculture, contributing to the systematics and molecular epidemiology of scuticociliate in Turkey.

Article Synopsis
  • The opportunistic fish pathogen Vibrio scophthalmi significantly harms olive flounder and turbot, leading to major economic losses in seafood production in Far East Asia.
  • This study focuses on the role of LuxR, a quorum sensing master regulator, revealing that it enhances poly-hydroxyalkanoate (PHA) biosynthesis while inhibiting biofilm formation in V. scophthalmi.
  • The research suggests that targeting LuxR could be an effective strategy to mitigate the pathogen's harmful effects, thus improving seafood production by interfering with its various physiological functions.

Fish skin, the mucosal site most exposed to external antigens, requires protection by an efficient local mucosal immune system. The mucosal reserve of IgM is recognized as an immune strategy that blocks pathogen invasion to maintain homeostasis, whereas the mechanism of skin-associated local IgM production induced by mucosal antigens is not well know. In this study, we found that the skin of flounder (Paralichthys olivaceus) was equipped with the immune cellular and molecular basis for processing mucosal antigens and triggering local specific responses, i.

Developing superior cancer cell recognition probes is crucial for the development of tumor therapy and cancer early screening materials. In this study, we first achieved effective recognition of MCF-7 breast cancer cells using natural collagen probes. Through cell adhesion, cancer cell selective capture, and flow cytometry techniques, the binding efficiency of mammalian-derived collagens (bovine Achilles tendon collagen, porcine skin collagen) and fish-derived collagens (turbot skin collagen, grass carp skin collagen, mandarin fish skin collagen) to cancer cells (MCF-7 breast cancer cells) and normal cells (human umbilical vein endothelial cells, HUVECs) was analyzed and compared.

Ras-related associated with diabetes (RRAD) is a member of the Ras GTPase superfamily that plays a role in several cellular functions, such as cell proliferation and differentiation. In particular, the superfamily acts as an NF-κB signaling pathway inhibitor and calcium regulator to participate in the immune response pathway. A recent transcriptome study revealed that was expressed in the spleen of disease-resistant Japanese flounder () individuals compared with disease-susceptible individuals, and the results were also verified by qPCR.
