Campylobacter jejuni is a leading bacterial cause of human enterocolitis. Molecular genetic characterization of this pathogen has been hampered by the lack of genetic tools that are functional in this organism. Cloning vectors commonly used in other organisms usually do not replicate within C. jejuni. To develop a system for functional analysis of C. jejuni genes, a small plasmid (pCJ01) identified in a poultry isolate of C. jejuni was sequenced and characterized in this study. By using inverse PCR, the full sequence of pCJ01 was amplified and subsequently determined. Results indicate that pCJ01 is a circular molecule of 3212 bp, with a G + C content of 33.5%. A typical plasmid replication origin with iteron sequences is identified upstream of the DNA sequences encoding replication initiation proteins. Four open reading frames (ORFs) are present in pCJ01. ORF1 and ORF2 share high homology with the putative RepA and RepB proteins, respectively, of known C. coli plasmids. ORF3 and ORF4, of unknown function, do not exhibit homology with any sequences deposited in the GenBank database. Hydropathy analysis predicts that ORF3 and ORF4 contain multiple stretches of hydrophobic amino acids, suggesting that they may encode transmembrane proteins. Since pCJ01 is a small plasmid and can be readily prepared from C. jejuni, it may be modified for use in molecular characterization of C. jejuni virulence genes.
