Transcriptome Analysis Reveals New Insight of Fowl Adenovirus Serotype 4 Infection.

ABSTRACT: Since 2015, Fowl adenovirus serotype 4 (FAdV-4) infection has caused serious economic losses to the poultry industry worldwide. We isolated and identified the FAdV-4 strain NP, from infected chickens on a layer farm, using chicken embryo allantoic cavity inoculation, electron microscopy, viral genome sequencing, and regression analysis. To explore the pathogenesis of FAdV-4 infection, we conducted transcriptome sequencing analysis of the liver in chickens infected with FAdV-4, using the Illumina® HiSeq 2000 system. Two days after infection with the FAdV-4 NP strain, 13,576 differentially expressed genes (DEGs) were screened in the liver, among which, 7,480 were up-regulated and 6,096 were down-regulated. Gene ontology (GO) analysis indicated that these genes were involved in 52 biological
