A total of 254 isolates of Campylobacter jejuni and three isolates of Campylobacter coli, isolated from Sweden, Canada, and Egypt, were screened for kanamycin resistance. Eight strains of C. jejuni contained large plasmids that carried the aphA-3 kanamycin-resistance marker. In six plasmids, the aphA-3 gene was located downstream of an apparent insertion sequence, designated IS607*, which showed a considerable similarity to IS607, characterized on the chromosome of some Helicobacter pylori strains. In contrast, the other plasmids carried the aphA-3 gene as a part of a resistance cluster. This included three resistance markers encoding 6'-adenylyltransferase (aadE), streptothricin acetyltransferase (sat), and 3'-aminoglycoside phosphotransferase type III (aphA-3). The genetic organization of this resistance cluster suggests that it has been acquired by C. jejuni from a Gram-positive organism. The IS607* element was also observed in kanamycin-susceptible strains of C. jejuni on plasmids mediating tetracycline resistance. The kanamycin-resistance phenotype transferred along with tetracycline resistance by conjugation from four representative C. jejuni strains to a recipient strain of C. jejuni. The kanamycin-resistance determinant (aphA-3) was stably transferred from one of the four C. jejuni strains to a recipient strain of Escherichia coli. However, the C. jejuni plasmid, which also carries the tetO gene, was not maintained in E. coli. Pulsed-field gel electrophoresis revealed the integration of approximately 50 kb of the plasmid into the chromosome of the E. coli recipient.
