Specificity and benefits of an exclusion mechanism for a mobile genetic element in Bacillus subtilis
The horizontal transfer of mobile genetic elements, including Integrative and Conjugative Elements (ICEs), plays an essential role in bacterial evolution by helping to promote the spread of genes involved in antibiotic and heavy metal resistance, metabolism, symbiosis, and pathogenicity. Like …

Conjugative transfer and expression of an integrative and conjugative element in Pectobacterium atrosepticum : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… Genetic Elements, the means of Horizontal Gene Transfer enabling rapid exchange of genetic information between bacterial populations. Integrative and Conjugative Elements (ICEs) are Mobile Genetic Elements (MGEs) that are transferred largely by conjugation between two bacterial cells and able to …

Characterization of a bifunctional cell wall hydrolase in the mobile genetic element ICEBsJ
Integrative and conjugative elements (ICEs) are mobile genetic elements that are normally found stably integrated into bacterial chromosomes, but under certain situations can excise and transfer to a recipient cell through conjugation. ICEs contain a set of genes that encode the molecular machinery …

Transcriptional regulation of mobilization and transfer of the Bacteroides conjugative transposon CTnDOT
… mobile genetic elements. One such element is a conjugative transposon (sometimes referred to as an integrative conjugative element, or ICE) called CTnDOT, which is a 65 kb ICE that encodes resistance to the antibiotics erythromycin and tetracycline. A notable feature of CTnDOT is that excision …

Single cell analysis of bacterial communication and gene transfer by Enterococcus faecalis
… resistance. E. faecalis is particularly good at transferring antibiotic resistance by mechanisms like conjugation and conjugative transfer of plasmids can occur at a high frequency without antibiotic selection. Conjugative plasmid pCF10 encodes tetracycline resistance and transfer between E. …

Acquisition and Exclusion of Pathogenicity Island 1 (PAPI-1) in Pseudomonas Aeruginosa
Horizontal gene transfer (HGT) allows rapid exchanges of large genetic elements and is known to play an important role in bacterial evolution and adaptation. Conjugative transfer of genomic islands (GIs) has recently been reported in the opportunistic pathogen Pseudomonas aeruginosa. PAPI-1, one of …

Characterization of an agrobacterial plasmid inducible for transfer by mannopine and evolution of the core replication and transfer functions of repabc plasmids with class i quorum-sensing and transfer systems
… and a subset of these plasmids encode a conjugative transfer system allowing these biologically relevant elements to transfer between and among species of bacteria. Perhaps the best-studied transfer system of the repABC plasmids is the Class I system composed of a type four secretion …

Functional dissection of ParB homologue and global regulatory protein KorB of RK2
… regulate replication, stable inheritance and conjugative transfer functions. KorB (358 aa) has dual roles as a global regulator and as an active partitioning protein. This study focuses on its role as a global regulatory protein and its interaction with DNA, RNAP and other repressor proteins …

Biological control of a plant pathogen and pest by expression of a cloned Serratia marcescens chiA gene and Bacillus thuringiensis cryIA(c) gene in endophytic bacteria
… Rift, H. seropedicae and Citrobacter sp.AJl by conjugative transfer and electroporation and were shown to express the gene at varying levels. pKTCl and pMTC33 carrying the 1 and 2nd generation tacchiA cassettes on pKT240 and pML122respectively were not stably maintained in P. fluorescens Rift or …

Resistencia a beta-lactámicos y fluoroquinolonas en Salmonella enterica. Mecanismos moleculares y elementos de movilización génica
… were found in non-typeable plasmids. The conjugative transfer of ESBL/AmpC genes was successful in 8 of the 11 strains, co-transferring in most of the cases other additional resistance genes. The stability of the ESBL/AmpC phenotype was evaluated after 100 daily passages in the absence of …
