Figure 1From: Transcriptional approach to study porcine tracheal epithelial cells individually or dually infected with swine influenza virus and Streptococcus suisHost genes are modified in greater numbers in NPTr cells co-infected by S. suis and swine influenza virus. Venn diagram showing the total numbers of upregulated (A) or downregulated (B) genes in NPTr cells (n = 4 replicates per group) infected with S. suis, H1N1, or co-infected with S. suis/H1N1 when compared to mock-infected cells, as determined by Agilent microarray study. Differentially expressed genes were defined by fold changes greater than 2-folds (upregulation or downregulation) with an accompanying p-value ≤ 0.05.Back to article page
