چکیده

Suppression subtractive hybridization (SSH) was used to generate a subtracted cDNA library enriched with gene transcripts differentially expressed in the spleen of orange-spotted grouper Epinephelus coioides after 5 days of infection with Singapore grouper iridovirus (SGIV). In the forward and reverse-subtracted libraries, 260 and 153 non-redundant expressed sequence tags (EST), respectively, were identified. These annotated genes responding to SGIV infection were grouped into eight gene categories related to immunity, cell structure, transcription-translation, cell signalling, metabolism, mitochondrial proteins, ribosomal proteins and unknown or hypothetical proteins. A DNA microarray containing all the differentially expressed genes was constructed, and the gene expression patterns in different tissues were investigated in virus-infected E. coioides. Of these genes, four associated with the infection processes were identified and further investigated by quantitative real-time PCR. These results provide new insights into the molecular basis of host-pathogen interactions in E. coioides, and will help the development of control strategies against SGIV infection.

Cloning of an orange-spotted grouper (Epinephelus coioides) Mx cDNA and characterisation of its expression in response to nodavirus.

Molecular cloning and nucleotide sequencing of cDNA encoding an orange-spotted grouper (Epinephelus coioides) homolog of Mx ("OsgMx") was conducted and its possible role in fish immunity was analysed. Similar to mammalian Mx, the OsgMx are members of a family of interferon-inducible genes that are expressed by cells in response to nodavirus and iridovirus naturally-infected. Expression of OsgMx...

Piscine iridoviruses infect a wide variety of fish and are classified into three genera: Lymphocystivirus, Ranavirus and Megalocytivirus. Lymphocystiviruses cause non-fatal, dermal infections, while ranaviruses and megalocytiviruses produce devastating, systemic infections with mortality reaching up to 100%. Although both ranaviruses and megalocytiviruses cause fatal systemic infections, they i...
