Abstract
We found and sequenced intervening sequences (IVSs) in the PCR-amplicons of 16S rRNA genes of 3 strains of Campylobacter rectus, 2 strains of C. curvus and 2 strains of C. sputorum. The lengths of the IVSs were 140 to 233 bp. The IVSs of C. rectus were identical and had a sequence homology of 55 to 79% against those of C. curvus and C. helveticus. The IVSs of C. sputorum were 97.9-100% homologous but poorly homologous to the other IVSs. In spite of the diversities of the lengths and the nucleotide sequences, all of the IVSs were located at the same position in the 16S rRNA genes.Keywords
