Two flagellin gene (flaA and flaB) sequences and the adjacent gene loci of urease-positive thermophilic Campylobacter (UPTC)(1) were examined. The flagellin gene sequences (1.7 kb) and adjacent gene loci of the two UPTC isolates (89049 and A3), obtained from animal hosts, were very similar to those of C. lari RM2100, C. jejuni, and C. coli. However, the structure and loci of the two flagellin genes (1.46-1.47 kb) and the adjacent gene loci of a UPTC strain obtained from the natural environment (NCTC12892) clearly differed from those of C. lari RM2100 and UPTC obtained from animal hosts. The two flagellin genes of UPTC 89049 and A3 were located between topA /CLA0518 and CLA0521, whereas those of NCTC12892 were located between topA and CLA0521. The sequences involved in regulation of flagellin expression, like sigma(28), sigma(54) and transcription termination signals, were conserved in all isolates. The characteristic direct repeat sequences containing a complete repeat unit of 5'-TCTTTAAAACAAC-3' were located in the intergenic regions between flaA and flaB in UPTC89049 and A3, but not in NCTC12892. The deduced amino acid sequence alignment revealed that the two flagellin genes in NCTC12892 had a deletion of the variable region of flagellin, which was reported previously to be modified by pseudaminic acid in C. jejuni and C. coli.Consequently, these results may possibly suggest that the length of the flagellin is related to pathogenicity and colonization of Campylobacter.
