Fig. 2From: Supplemental N-acyl homoserine lactonase alleviates intestinal disruption and improves gut microbiota in broilers challenged by Salmonella TyphimuriumEffect of N-acyl homoserine lactonase (AHLase) on serum diamine oxidase activity of broilers challenged by Salmonella Typhimurium. a-c Values within a column with unlike superscript letters differ significantly (P < 0.05). NC, negative control (broilers were free of challenge); PC, positive control (broilers were challenged with S. Typhimurium); AHLase, PC broilers supplemented with 10 U/g AHLaseBack to article page
