Brain (a) and lung (b) homogenates from the TG pigs (n = 5) displayed enhanced antibacterial activity against G. parasuis when compared with those from the WT pigs (n = 6). Brain or lung tissues of 400 mg from each pig were homogenized and centrifugated, and heat-inactivated supernatants were mixed with G. parasuis (2.5 × 10³ colony-forming units) at 37 °C for 1 h. The number of surviving bacteria in the mixture was counted. Data are presented as mean ± SD and plotted from three independent experiments. ** p < 0.01, unpaired one-tailed Student’ s t-test.
