Effects of PCA and Que on cell number and LDH activity after infection with ETEC K88 in IPEC-1 cells. Cells were pretreated with 40 μmol/L PCA or 10 μmol/L Que for 24 h and then infected with or without 1 × 108 ETEC K88/mL for 2 h. a Cell number. b LDH activity. Values are means ± SE, n = 6. a–cDifferent letters represent a significant difference, P < 0.05. LDH, lactate dehydrogenases; IPEC-1, intestinal porcine epithelial cell 1
