چکیده
The red sea bream iridovirus (RSIV) belonging to genus Megalocytivirus is responsible for iridoviral disease (RSIVD) in marine and freshwater fishes. Although several diagnostic assays RSIV have been developed, sensitivity (DSe) specificity (DSp) of real-time polymerase chain reaction (PCR) are not yet evaluated. In this study, we developed a TaqMan probe-based PCR method evaluated its DSe DSp. To detect RSIV, the probe primers were designed based on consensus sequences major capsid protein (MCP) genes from megalocytiviruses including infectious spleen kidney necrosis virus (ISKNV), turbot reddish body (TRBIV). shown be specific ISKNV, TRBIV-types megalocytiviruses. A 95% limit detection (LOD95%) was determined 5.3 viral genome copies/?L plasmid DNA containing MCP gene RSIV. DSp assay field samples (n = 112) compared with those conventional found 100% 95.2%, respectively. quantitative results SYBR Green significantly different. may used as an appropriate tool qualitative analysis.

Rapid diagnosis of red sea bream iridovirus infection using the polymerase chain reaction.
A simple and sensitive polymerase chain reaction (PCR) based assay is described for detection of the red sea bream iridovirus (RSIV) in infected fish. The assay involves amplification of a portion of the ribonucleotide reductase small subunit (RNRS) gene of the virus from DNA isolated from the spleen. The system was tested on red sea bream following an experimental infection. In our infection m...
