Abstract :
Sea cucumber skin ulceration syndrome (SUS) is associated with a diverse range of bacterial and parasitic pathogens. Nonetheless, research efforts aimed at identifying novel pathogens and developing effective prevention and control strategies remain limited. In this study, we identified a strain of Photobacterium damselae and designated it as P. damselae sea cucumber xiapu (P. damselae SCXP), recognizing it as a new pathogenic bacterium associated with SUS in Apostichopus japonicus. We developed a detection method using a TaqMan probebased qPCR assay specific to P. damselae SCXP, which supports the rapid diagnosis of this pathogen. Additionally, artificial infection experiments confirmed that P. damselae SCXP facilitates the progression of SUS in Apostichopus japonicus. Drug sensitivity analysis revealed that the strain was highly sensitive to 16 antibiotics (e. g., novobiocin, ceftazidime, ceftriaxone) with inhibition zone diameters >= 20 mm, providing a reference for aquatic drug use. Furthermore, transcriptomic analyses were conducted on the coelomocytes of Apostichopus japonicus infected with P. damselae SCXP. The KEGG enrichment analysis identified distinct signaling pathways that were differentially expressed in the P. damselae SCXP-infected groups at 6, 12, and 24 h post-infection. At the 6-h mark, the focal adhesion pathway exhibited the highest number of differentially expressed genes (DEGs), followed by the PI3K-Akt, mTOR, and MAPK signaling pathways. At 12 h post-infection, the complement and coagulation cascades showed the highest number of DEGs, followed by phagosome-related pathways. By 24 h, the proteasome and lysosome pathways demonstrated an increased number of DEGs. Venn diagram analysis revealed that P. damselae SCXP infection suppressed the expression of several genes, including deoxyribonuclease-1 (DNase I) and acid-sensing ion channel 1-like protein (ASIC1), as validated by qRT-PCR. This study constitutes the first comprehensive investigation into the transcriptomic profile of Apostichopus japonicus coelomocytes in response to P. damselae SCXP infection. Future research endeavors should concentrate on elucidating the roles of DNase I and ASIC1 protein, as these elements may have significant implications for the development of targeted prevention and control strategies. Our study offers a theoretical foundation for the prevention and management of P. damselae-induced SUS in sea cucumbers.

Abstract :
【背景】大黄鱼(Larimichthys crocea)作为中国特色海水养殖鱼种,具有重要经济价值和产业地位,已成为中国海水养殖产量较高的鱼类之一。然而,随着集约化养殖的快速发展,多种因素导致养殖环境恶化,造成病害频发,对大黄鱼养殖业造成重大经济损失。其中,以盾纤毛虫病为代表的寄生虫病近年来日益严重。【目的】本研究旨在分离并鉴定感染大黄鱼的盾纤毛虫种类,研究其病原学特征,以期为盾纤毛虫病防控提供理论基础。【方法】本研究从宁德海区某大黄鱼养殖渔排采集锥体虫与盾纤毛虫共感染的鱼体样品,成功分离、培养并鉴定盾纤毛虫种类,建立稳定的体外培养体系。利用体外培养体系,评估盾纤毛虫在不同温度(0、10、20、25、26、28、30℃)、pH(5.5、6.5、7.4、8.5、9.0)及盐度(0、5、10、20、30)等培养条件下的增殖特性。同时,开展体外药物敏感性实验,评估常用水产抗虫药物的杀虫效果。【结果】形态学观察结合cox1和18S rRNA基因系统发育分析表明,本研究分离的盾纤毛虫为贪食迈阿密虫(Miamiensis avidus)。环境耐受性实验结果显示,虫体在温度为0℃条件下12 h内全部死亡,在温度为30℃条件下种群密度逐渐下降;温度为10℃时仍可增殖但显著低于对照组(20℃),而在温度为25℃时与对照组差异不显著,提示该虫对高温(> 25℃)较为敏感。盐度实验表明,虫体在淡水中无法存活,在盐度10条件下可增殖但密度显著低于对照组(盐度30),而盐度20条件下与对照组无显著差异,表明其具备较广的盐度耐受性。pH实验结果表明,虫体在pH 5.5和pH 9.0下仍能增殖,但密度显著低于对照组(pH 7.4);在pH 6.5和pH 8.5下与对照组差异不显著,提示其具有较强的pH适应性。体外药物敏感性实验显示,香芹酚在低剂量(100 mg/kg)即可显著杀灭贪食迈阿密虫。【结论】本研究首次从中鱼阶段的大黄鱼中分离出盾纤毛虫,并鉴定其为贪食迈阿密虫,系统阐明了环境因子对其增殖的影响,并在常用水产药物中筛选出高效抗虫药物香芹酚。这些研究结果不仅有助于理解大黄鱼源贪食迈阿密虫的生物学特性,也为盾纤毛虫病的科学防控提供了理论基础。

Abstract :
Large yellow croaker (Larimichthys crocea) farming dominates the marine aquaculture industry in China. However, the epidemic outbreaks of visceral white nodules disease (VWND), caused by bacterial pathogen Pseudomonas plecoglossicida, have emerged as a significant concern within the large yellow croaker industry. Although vaccination is considered to be an effective method for preventing and controlling P. plecoglossicida infection, there is currently no commercially available vaccine targeting this bacterium. In the present study, the outer membrane porin F (OprF) of P. plecoglossicida was characterized and revealed a high sequence similarity with that of other Pseudomonas species. The recombinant OprF protein (rOprF) produced in Escherichia coli was then evaluated for its immunogenicity and protective role against P. plecoglossicida in large yellow croaker. The rOprF was identified to have immunogenicity by Western blot using large yellow croaker anti-P. plecoglossicida sera. Additionally, the indirect immunofluorescence assay (IIFA) provided evidence indicating the surface exposure of OprF in P. plecoglossicida. Fish vaccinated twice via intraperitoneal (IP) injection with the purified rOprF combined with commercial adjuvant ISA 763A VG exhibited a relative percent survival (RPS) of 70.60% after challenge with virulent P. plecoglossicida strain through immersion. The administration of rOprF resulted in a notable increase in specific serum antibody levels and serum lysozyme activity compared to the control groups. The immune-related genes in the spleen and head kidney of rOprF-vaccinated fish were remarkably upregulated compared with the PBS-vaccinated sham group after the P. plecoglossicida challenge. In summary, the findings of this study suggest that rOprF exhibits considerable potential in inducing a robust immune response, making it a viable candidate for vaccination against P. plecoglossicida infection in large yellow croaker.
