We found that ROS, cytochrome c, mitochondrial membrane potential (Ψm), caspase-3 activity, ATP production, hepatic CFU, ALT, and AST, which were initially increased by Salmonella infection, significantly (P < 0.05) decreased by cinnamaldehyde treatment at 1, 3, and 5 days postinfection (DPI). Here, GPT is linked to Salmonella Infections.
