Primary diagnosis and surveillance of white spot syndrome virus in wild and farmed crawfish (Procambarus clarkii, P. zonangulus) in Louisiana, USA.

Infectivity and Physiological Effects of White Spot Syndrome Virus (wssv) in Farmed Louisiana Red Swamp Crayfish (procambarus Clarkii)

Aeromonas hydrophila, one reason causing the death of freshwater crayfish Procambarus clarkii (Girard, 1852)

Procambarus clarkii crayfish has been developed as an excellent animal model to study the characteristics and pathogenesis of white spot syndrome virus and the host defense mechanisms of crustacean. However, due to pathogen infections of crayfish in Chinese farms, research based on this model has been slowed down. Using triplex polymerase chain reaction, we found the virulence Aeromonas hydroph...

Comparative transcriptome analysis reveals three potential antiviral signaling pathways in lymph organ tissue of the red swamp crayfish, Procambarus clarkii.

The red swamp crayfish (Procambarus clarkii) is one of the most economically important farmed aquatic species in China. Compared with its relatively well-known antibacterial and antifungal mechanisms, the antiviral mechanism is still unclear. We used Illumina-based RNA sequencing and bioinformatic technology to obtain high-quality sequence reads from the crayfish lymph organ. A total of 5933 di...

Identification and characterization of intestine microRNAs and targets in red swamp crayfish, Procambarus clarkii infected with white spot syndrome virus

MicroRNAs (miRNAs) are small non-coding endogenous RNA molecules that play important roles in the innate immunity system of invertebrates, especially in the aspect of antivirus. In the present study, high-throughput small RNA Illumina sequencing systems were used to identify differentially expressed miRNAs (DEMs) from the intestines of Procambarus clarkii that were infected with white spot synd...

Novel Insights into Antiviral Gene Regulation of Red Swamp Crayfish, Procambarus clarkii, Infected with White Spot Syndrome Virus

White spot syndrome virus (WSSV), one of the major pathogens of Procambarus clarkii, has caused severe disruption to the aquaculture industry of P. clarkii in China. To reveal the gene regulatory mechanisms underlying WSSV infection, a comparative transcriptome analysis was performed among WSSV-infected susceptible individuals (GS), viral resistant individuals (GR), and a non-infected control g...
