Enterotoxin-like activity produced by Campylobacter jejuni and Campylobacter coli isolated from patients and healthy controls in Algeria

Abstract In our earlier studies, hexammine ruthenium (III) chloride (HRC) was found to eliminate the pBR322 plasmid from E. coli HB101 with 100% frequency. However, this plasmid was not eliminated by other known curing agents, such as acridine orange, sodium dodecyl sulphate (SDS), rifampicin or temperature conditions. In our present communication, we report the sensitivity of a variant of plasmid pBR322 to curing agents which were not effective on the parent plasmid.
