title: An improved physical and genetic map of Campylobacter jejuni NCTC 11168 (UA580).
abstract: Campylobacter jejuni is recognized as the major cause of food-borne gastrointestinal disease in the developed world. To facilitate the molecular genetic analysis of this pathogen, an approximately 18-fold redundant Tropist3 cosmid library was constructed from C. jejuni NCTC 11168 genomic DNA. The cosmid library was partially ordered by hybridization to 15 pulsed-field electrophoresis (PFGE) restriction fragments. This analysis confirmed the estimated size of the genome to be 1730 kb, but suggested discrepancies in some regions of the published physical map. The precise locations of two of the three rRNA gene clusters were mapped using a combination of restriction fingerprinting, sample sequencing and riboprobing. Additionally, 15 further genes were located on the revised map. A more detailed physical and genetic map of C. jejuni NCTC 11168 is presented.
