JOURNAL OF VIROLOGICAL METHODS 18/10/05 Quantitative detection of a marine fish iridovirus isolated from large yellow croaker, Pseudosciaena crocea, using a molecular beacon. JOURNAL OF VETERINARY MEDICAL SCIENCE - 2018 - Assessment of fish iridoviruses using a novel cell line GS-1, derived from the spleen of orange-spotted grouper Epinephelus coioides (Hamilton) and susceptible to ranavirus and megalocytivirus. Abstract A new cell line (GS-1) was developed from the spleen tissue of the orange-spotted grouper, Epinephelus coioides applied for viral infection studies of fish ranavirus and megalocytivirus.

The cells proficiently multiplied in Leibovitz’s L-15 medium supplemented with 10% fetal bovine serum at temperatures between 20°C and 32°C. Morphologically, the cell line comprised fibroblast-like cells, and this was confirmed by immunostaining with vimentin, fibronectin, and desmin antibodies. The optimal temperature for grouper iridovirus (GIV) and infectious spleen and kidney necrosis virus (ISKNV) proliferation in GS-1 cells was 25°C, and the highest titer of GIV was 108.4 TCID50/ml, and the highest titer of ISKNV was 105.2 TCID50/ml.

Electron micrographs showed that the mean diameter of GIV virions was 180−220 nm, which was larger than ISKNV virions (160−200 nm). FRONT.

Introduction Singapore grouper iridovirus (SGIV) is a novel marine fish virus isolated from diseased groupers (Qin et al., 2001).

The clinical symptoms of SGIV-challenged fishes are hemorrhage and enlargement of the spleen. This lethal pathogen has caused considerable economic damage in groupers, with more than 90% mortality (Qin et al., 2003). To date, the morphogenesis, biochemical pathology, genome, transcriptome, proteomics, and entry mechanisms of SGIV have been systematically studied (Qin et al., 2003; Song et al., 2004; Wang et al., 2014). SGIV is an icosahedral virus with diameter of 154–176 nm, and it belongs to the genus Ranavirus and family Iridoviridae (Qin et al., 2001, 2003). Autophagy is a conserved catabolic process that maintains cellular homeostasis by sequestering damaged organelles or misfolded proteins in the autophagosome and fusing with lysosomes for degradation and recycling (Xie and Klionsky, 2007; Klionsky et al., 2011).
