Plasmid-mediated chromosomal gene transfer in Neisseria gonorrhoeae.
An indigenous Neisseria gonorrhoeae conjugative plasmid, pLE2450, was tested for its ability to mediate chromosomal gene transfer between gonococcal strains. Plasmid-mediated chromosomal transfer was detected at a low frequency and can be used to establish certain linkage relationships between amino acid and antibiotic resistance markers.
متن کاملGene transfer in Neisseria gonorrhoeae.
The ability of bacteria to exchange deoxyribonucleic acid (DNA) endows these organisms with greater genetic variability and increased capability to adapt to changing environments. Many bacteria have evolved transformation and conjugation systems to effect this exchange, whereas others achieve it through the action of bacteriophages. In Neisseria gonorrhoeae no transducing bacteriophages have be...
متن کاملPlasmid-mediated beta-lactamase production in Neisseria gonorrhoeae.
Several beta-lactamase-producing, penicillin-resistant strains of Neisseria gonorrhoeae were examined for R plasmids. Penicillin-resistant strains isolated from men returning from the Far East and their contacts contained a 4.4 x 10(6)-dalton plasmid in common. Transformation studies and the isolation of a spontaneous penicillin-susceptible segregant showed that the structural gene for beta-lac...
متن کاملAntimicrobial susceptibility of Neisseria gonorrhoeae in Zaire: high level plasmid-mediated tetracycline resistance in central Africa.
OBJECTIVE To determine the in vitro antimicrobial susceptibility of gonococcal strains isolated in 1988 among female prostitutes in Kinshasa, Zaire and to characterise strains with high level tetracycline resistance. METHODS Minimal inhibitory concentrations of 8 antimicrobials were measured by agar dilution technique. Plasmid-profiles and serovars were determined. RESULTS Two hundred and t...
متن کاملSequence Features Contributing to Chromosomal Rearrangements in Neisseria gonorrhoeae
Through whole genome sequence alignments, breakpoints in chromosomal synteny can be identified and the sequence features associated with these determined. Alignments of the genome sequences of Neisseria gonorrhoeae strain FA1090, N.gonorrhoeae strain NCCP11945, and N. gonorrhoeae strain TCDC-NG08107 reveal chromosomal rearrangements that have occurred. Based on these alignments and dot plot pai...
