Gene expression in the chicken caecum following oral infection with S . Enteritidis on the day of hatching. Chickens were infected on the day of hatching and expression of 45 selected genes in the chicken caecum was determined by real-time PCR including the expression in the age-matched, non-infected controls. Left panel, gene expression in the non-infected chickens, mind the increase in the expression of IgY and IgA in the second week of life. Right panel, gene expression in the caecum of infected chickens, mind the dramatic changes in the total caecal expression within 48 h after infection and also an increase in IgY and IgA expression during the recovery phase.
