Figure 1From: Comparative expression of Toll-like receptors and inflammatory cytokines in pigs infected with different virulent porcine reproductive and respiratory syndrome virus isolatesRectal temperature changes in pigs at 0 to 15 days post-inoculation of highly pathogenic PRRSV strain BB0907 (HP), low pathogenic PRRSV strain NT0801 (LP), NT0801 derivative strain NT0801-F70 (LP-der; propagated in MARC-145 cells to 70 passages), and Dulbecco’s modified Eagle’s medium (DMEM) (Control). Each data point represents the mean ± standard deviation (SD) generated from 6 pigs in each group.Back to article page
