AI Article Synopsis

  • Koi carp can develop neoplasia, including seminomas, which are tumors of the testes, despite being uncommon.
  • A case study involved a koi carp with coelomic swelling, leading to surgical intervention that revealed enlarged testes.
  • The seminoma diagnosis was based on cellular examination, indicating that cytology could be a valuable, cost-effective tool for early diagnosis of such tumors in veterinary clinics.

Article Abstract

Koi(Cyprinus carpio) is an ornamental variety of common carp frequently kept as pets. Given their long lifespan, neoplasia, albeit uncommon, may occur in these animals, and only a few studies have faced their cytological diagnosis. In the present case, a koi carp was referred to the clinicians due to coelomic swelling. The carp underwent surgery, which revealed an enlargement of both testes. Testicular samples were cytologically and histologically examined. The lesion was diagnosed as a seminoma since it was composed of round, large, atypical, and often multinucleated cells with round central nuclei and moderate cytoplasm. These tumors had the same appearance as seminomas in mammals and should be considered among differential diagnoses when coelomic swelling occurs in koi carp. Seminomas in koi carp are diagnosed histologically, but cytology, a rapid and cheap exam executable in all veterinary clinical facilities, could be a relevant preliminary diagnostic tool that may influence the entire diagnostic process.

Development of Sensitive R6G/AuNCs Ratiometric Fluorescent Probes for the Detection of Biogenic Amines in Fish Products.

Int J Mol Sci

Biogenic amines (BAs), produced in fish and seafood due to microbial contamination, pose significant health risks. This study introduces a novel ratiometric fluorescent probe, synthesized by integrating rhodamine 6G(R6G) and gold nanoparticles (AuNCs), for the sensitive and specific detection of BAs. The probe operates on the principle of BAs hydrolysis, catalyzed by diamine oxidase, to produce hydrogen peroxide (HO), which selectively quenches the fluorescence of AuNCs at 620 nm, while the fluorescence of R6Gat 533 nm remains unaffected.

A 60-day feeding trial was conducted to evaluate the combined effect of dietary soy phytoestrogens, specifically genistein and daidzein, on the gonadal recrudescence and maturation of male Cyprinus carpio (Linnaeus, 1758). Adult male C. carpio (60 ± 10 g) were fed with a diet with no added genistein or daidzein (C), 110 mg/100 mg genistein (GL), 210 mg/100 g genistein (GH), 4 mg/100 g daidzein (DL), 8 mg/100 g daidzein (DH), combination of 110 mg/100 mg genistein and 4 mg/100 g daidzein (DGL, equivalent to 17.

Cyvirus cyprinidallo 2 (CyHV-2) is the pathogen of herpesviral hematopoietic necrosis (HVHN) that mainly infects goldfish Carassius auratus and crucian carp C. carassius and is characterized by high infectivity and pathogenicity. The availability of rapid and convenient detection methods is essential for early detection of CyHV-2.

Immunological memory in a teleost fish: common carp IgM B cells differentiate into memory and plasma cells.

Article Synopsis
  • All vertebrates, from ancient fishes to mammals, possess adaptive immunity and immunological memory, although the specific responding cells in fish have not been clearly defined.
  • Researchers infected common carp with a cnidarian parasite and observed that B cells proliferated and showed signs of differentiation, indicating they can form memory cells.
  • The study revealed that these memory B cells can persist for at least six months, alongside identifying a distinct population of plasma cells, suggesting that teleost fish possess the necessary immune components for effective long-term disease protection akin to other vertebrates.

The prevalence of heatwave and hypoxia events and their devastating impacts on aquatic ecosystems and fishery resources reinforces the priority of research to address the resilience and adaption mechanisms to these two stressors in important fish species. However, our understanding of the development of cross-tolerance of these two stressors in fish still limited. Here, we investigated the impacts of prior heatwave exposure on hypoxia tolerance and the underlying mechanisms in silver carp (Hypophthalmichthys molitrix), a species of considerable ecological and commercial importance.
