Abstract / Description of output

Campylobacter jejuni colonises the caecum of more than 90% of commercial chickens. Even though colonisation is asymptomatic, we hypothesised that it is mediated by activation of several biological pathways. We therefore used chicken-specific 20K oligonucleotide microarrays to examine global gene expression in C. jejuni-challenged birds. Microarray results demonstrate small but significant fold-changes in expression of 270 genes 20 h post-challenge, corresponding to a wide range of biological processes including cell growth, nutrient metabolism and immunological activity. Expression of NOX1 (2.3-fold) and VCAM1 (1.5-fold) were significantly increased in colonised birds (P
