Campylobacter jejuni Utilization of Mucin


ABSTRACT: While growing in the human intestine, C. jejuni grows within the mucus layer. The largest constituents of this layer are the large mucin glycoproteins. A transcriptomic profile of C. jejuni NCTC11168 growing in a mucin-containing minimal medium seeks to describe the effect of the presence of mucin proteins on the transcriptome of C. jejuni. Microarray data was collected from three independent biological replicates and 9 technical replicates for each biological replicate.

Campylobacter jejuni is a prevalent gastrointestinal pathogen in humans and a common commensal of poultry. When colonizing its hosts, C. jejuni comes into contact with intestinal carbohydrates, including L-fucose, released from mucin glycoproteins. Several strains of C. jejuni possess a genomic island (cj0480c-cj0490) that is up-regulated in the presence of both L-fucose and mucin and allows for the utilization of L-fucose as a substrate for growth. Strains possessing this genomic island show in  ...[more]
