Conjugative Plasmids of Neisseria gonorrhoeae
Many clinical isolates of the human pathogen Neisseria gonorrhoeae contain conjugative plasmids. The host range of these plasmids is limited to Neisseria species, but presence of a tetracycline (tetM) determinant inserted in several of these plasmids is an important cause of the rapid spread of tetracycline resistance. Previously plasmids with different backbones (Dutch and American type backbo...
متن کاملConjugative plasmids in Neisseria gonorrhoeae.
A conjugation system initially discovered in beta-lactamase-producing gonococci mobilized small non-selftransmissible R plasmids encoding beta-lactamase (penicillinase) production into other gonococci, Neisseria, and Escherichia coli. This conjugation system was mediated by a separate selftransmissible plasmid of 23.9 X 10(6) daltons, pFA2. Conjugative plasmids capable of mobilizing R plasmids ...
متن کاملNucleotide sequences and comparison of two large conjugative plasmids from different Campylobacter species.
Two large tetracycline resistance (TcR) plasmids have been completely sequenced, the pTet plasmid (45.2 kb) from Campylobacter jejuni strain 81-176 and a plasmid pCC31 (44.7 kb) from Campylobacter coli strain CC31 that was isolated from a human case of severe gastroenteritis in the UK. Both plasmids are mosaic in structure, having homologues of genes found in a variety of different commensal an...
متن کاملCharacteristics of conjugative R-plasmids from pathogenic avian Escherichia coli.
Three of four virulent avian Escherichia coli isolates transferred a single large molecular-weight R-plasmid to two recipient E. coli strains. Antibiotic resistances transferred included streptomycin (two isolates) and streptomycin-tetracycline-sulfa (one isolate). Production of colicin and siderophores, complement resistance, and embryo lethality present in the virulent isolates were not trans...
متن کاملTwo novel conjugative plasmids from a single strain of Sulfolobus.
Two conjugative plasmids (CPs) were isolated and characterized from the same 'Sulfolobus islandicus' strain, SOG2/4. The plasmids were separated from each other and transferred into Sulfolobus solfataricus. One has a high copy number and is not stable (pSOG1) whereas the other has a low copy number and is stably maintained (pSOG2). Plasmid pSOG2 is the first Sulfolobus CP found to have these ch...
