Role of Plasmids in Antibiotic Resistance of Campylobacter Spp. Isolated from ChildrenAylan A. Ali1, Ghalib H. Al-Bakri2, Duhuha S. Saliih11From Department of Biology, College of Science, University of Baghdad, Iraq.2From Department of Biotechnology, College of Science, Saddam University, Baghdad, Iraq. Six clinical isolates of Campylobacter were examined for the occurrence of conjugative plasmids carrying antibiotic resistance markers. Kanamycin resistance was conjugally transferred from donors to recipients in all cases which indicated that it is plasmid mediated while the resistance to Erythromycin was considered to be chromosomally mediated because it was never transferred by conjugation. The Tetracycline resistance in one Campylobacter strain was encoded on a self-transmissible plasmid, while in other donor strains it was considered to be chromosomally mediated or carried on non-conjugative plasmid because it failed to transfer by conjugation. The Ampicillin and Kanamycin resistance markers of C. jejuni D101 were co-transferred by conjugation to C. coli A9 which indicated that both markers are on the same plasmid. Aylan A. Ali, Ghalib H.
