Project description:Salmonella enterica Pullorum（S. Pullorum） is one of the most important pathogens in poultry. A better understanding of the immune response and molecular modulation resulting from infection by S. Pullorum will facilitates the control of this pathogen. In this study, we determined the relationships among identified differential expressed genes (DEGs) and pathways via deeply mining microarray data from Guangxi Huang Chicken challenged with S. Pullorum.
Project description:This study was conducted to evaluate the effects of dietary supplemental magnolol and honokiol in broilers infected with S. pullorum. A total of 360 one-day-old broilers were selected and randomly divided into four groups with six replicates: the negative control group (CTL), S. pullorum-infected group (SP), and the S. pullorum-infected group supplemented with 300 mg/kg honokiol (SPH) or magnolol (SPM). Chicks in the SP, SPH, and SPM groups were orally treated with a 0.5 ml (4×108 CFU/mL) S. pullorum solution at 5 days of age, while chicks in the control (CTL) group received the same amount of sterilized PBS at the same age.At 14 and 21 days of age, one chick from each replicate was randomly selected to be weighed and slaughtered by jugular exsanguination after a 12-h fasting period. The ileum samples were collected to analyze the differential expression genes.
