Project description:Purpose: This goal of this study was to explore the host transcriptomic responses in African swine fever virus experimentally infected pigs using RNA-Sequencing. Methods: RNAs acquired from ten different organ tissue samples were sequenced. Sequencing reads were preprocessed, aligned with the reference genome, assembled and expressions were estimated through bioinformatics approaches. Result: Several uprugulated DEGs were identified. Conclusion: We found important candidate genes and pathways for further testing in African swine fever virus infection in pig.
Project description:Complete genome sequencing and comparative phylogenomics of multiple African swine fever virus (ASFV) field isolates of the virulent East African p72 genotype IX viruses
Project description:In field studies and carefully controlled artificial infections, there is host variation in response to ASF infections. To better understand the mechanisms underlying this diversity and distinguish between resilient and susceptible pigs to African Swine Fever (ASF), the differentially expressed genes (DEGs) were studied between the recovered versus non-recovered pigs before and after an infection challenge and also among non-recovered animals over time. In total, 17 Babraham pigs were sampled. Twelve animals were randomly immunized with low virulent ASFV isolate, and the others received the sham vaccine. All animals were then challenged with the virulent ASFV isolate 18 days after the immunization. Except for five animals, all showed clinical signs and dead between 4 and 6 days later. RNA sequencing was done for whole blood samples collected pre-infection, one day, and one week post-infection.
