Characterization of the Factors Associated with SCCmec Mobility in Staphylococcus Aureus
… staphylococci is found on the chromosome in a genomic island designated Staphylococcal Chromosome Cassette mec or SCCmec. In addition to the resistance gene, mecA, SCCmec also contains site specific recombinase genes, ccrAB, that are capable of catalyzing the chromosomal excision and …

Caractérisation des systèmes d'exclusion des plasmides conjugatifs IncC
… de leur dissémination, tel que le Salmonella genomic island 1 (SGI1). Ces îlots participent eux aussi à la dissémination de gènes de résistance aux antibiotiques. L’objet de ce mémoire est de caractériser les systèmes d’exclusion des plasmides IncC, des mécanismes qui empêchent l’entrée d’un …

Adaptive Mechanisms of an Estuarine Synechococcus based on Genomics, Transcriptomics, and Proteomics
… for further molecular analysis. Comparative genomics between CB0101, WH7803, and WH7805 show that CB0101 contains more genes involved in regulation, sensing, and stress response. At the transcript and protein level, CB0101 regulates its metabolic pathways, transport systems, and sensing …

Microbial Evolution In Sea Ice: Communities To Genes
… analysis and G+C content were used to identify a genomic island in C. psychrerythraea strain 34H containing a number of genes encoding proteins involved in the degradation of abundant compatible solutes like glycine betaine. Furthermore, the positive growth of C. psychrerythraea strain 34H on …

A comparative and phylogenetic analysis of the genome of Pseudomonas aeruginosa
… the CF lung, P. aeruginosa is known to undergo genomic changes resulting in the progression to chronic infection and a worsening prognosis. The most notable example of this phenomenon is the switch to the mucoid phenotype resulting from frame-shift mutations in the mucA gene leading to …

A pan-genome wide association study to identify genes associated with invasive Streptococcus pneumoniae
… Subunits of PsrP secY2A2 pathogenicity island from RD10. Genes from RD6 and RD7 involved in transposing mobile genetic elements. Genes from RD2 RD8b, and RD12 participating in communication and competition. Genes from RD4 that assemble pilins into pili and anchor pili to the cell wall. …

Identifying The Structure Of Genomic Islands In Prokaryotes
… One of the important components of HGT is the genomic island (GI) which is a subsequence of the genome created by HGT. This research aims to identify the structures of the prokaryotic GIs that have a fundamental role in the adoption of prokaryotes and the impact of the species on the …

Resistencia a beta-lactámicos y fluoroquinolonas en Salmonella enterica. Mecanismos moleculares y elementos de movilización génica
… obtained in the previous part. The Salmonella Genomic Island type 1 (SGI1), carrying blaPSE-1, floR, aadA2, sul1 and tet(G) genes, was identified in all the strains, and a new variant was detected (GenBank JF775513). All the blaPSE-1-positive strains displayed indistinguishable or closely …

The role of genomic islands in virulence of Pectobacterium carotovorum subspecies brasiliensis on potatoes
… have evolved through independent acquisition of genomic islands (GIs). GIs are large chromosomal regions in bacteria that are acquired by horizontal gene transfer and often encode virulence factors. To address this hypothesis, the genomes of P. carotovorum subsp. carotovorum strains associated …

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
… conjugative transfer of Horizontally Acquired Island 2 (HAI2), an ICE that enhances virulence of the potato pathogen Pectobacterium atrosepticum SCRI1043, was investigated by assessing frequency of acquisition into strains of SCRI1043 in which HAI2 had been removed. HAI2 was transferred into …
