Abstract
Bacteria of the genus Pectobacterium are economically important plant pathogens that cause soft rot disease on a wide variety of plant species. Here, we report the genome sequence of Pectobacterium carotovorum strain SCC1, a Finnish soft rot model strain isolated from a diseased potato tuber in the early 1980's. The genome of strain SCC1 consists of one circular chromosome of 4,974,798 bp and one circular plasmid of 5524 bp. In total 4451 genes were predicted, of which 4349 are protein coding and 102 are RNA genes.

Abstract
IMP-8 metallo-β-lactamase was identified in Klebsiella pneumoniae sequence type 252 (ST252), isolated in a Portuguese hospital in 2009. blaIMP-8 was the first gene cassette of a novel class 3 integron, In1144, also carrying the blaGES-5, blaBEL-1, and aacA4 cassettes. In1144 was located on a ColE1-like plasmid, pKP-M1144 (12,029 bp), with a replication region of limited nucleotide similarity to those of other RNA-priming plasmids, such as pJHCMW1. In1144 and pKP-M1144 represent an interesting case of evolution of resistance determinants in Gram-negative bacteria.

Abstract
The resistance of Klebsiella pneumoniae BM4493, isolated in Ho Chi Minh City, Vietnam, to cefotaxime and aztreonam was due to production of a novel beta-lactamase, CTX-M-17. The bla(CTX-M-17) gene was borne by 7,086-bp plasmid pIP843, which was entirely sequenced and which was found to belong to the ColE1 family. The 876-bp bla(CTX-M-17) gene differed from bla(CTX-M-14) by 2 nucleotides, which led to the single amino acid substitution Glu289-->Lys. bla(CTX-M-17) was flanked upstream by an ISEcp1-like element and downstream by an insertion sequence (IS) IS903 variant designated IS903-C. The transcriptional start site of bla(CTX-M-17) was located 109 nucleotides upstream from the initiation codon in the ISEcp1-like element, which also provided the promoter sequences. Plasmid pIP843, which was non-self-transferable and nonmobilizable, contained five open reading frames transcribed in the same orientation. Regions homologous to sequences coding for putative RNA II and RNA I transcripts, a rom gene, which is involved in initiation of replication, and a cer-like gene, which is responsible for the stability of ColE1-like plasmids, were identified. Consensus sequences for putative replication (oriV) and transfer (oriT) origins were present. Results of primer extension experiments indicated that ISEcp1 provides the promoter for expression of bla(CTX-M-17) and may contribute to dissemination of this gene.

Abstract
Plasmid pTKH11, originally obtained by electroporation of a Klebsiella oxytoca plasmid preparation into Escherichia coli XAC, expressed a high level of an AmpC-like beta-lactamase. The enzyme, designated CMY-5, conferred resistance to extended-spectrum beta-lactams in E. coli; nevertheless, the phenotype was cryptic in the K. oxytoca donor. Determination of the complete nucleotide sequence of pTKH11 revealed that the 8,193-bp plasmid encoded seven open reading frames, including that for the CMY-5 beta-lactamase (blaCMY-5). The blaCMY-5 product was similar to the plasmidic CMY-2 beta-lactamase of K. pneumoniae and the chromosomal AmpC of Citrobacter freundii, with 99.7 and 97.0% identities, respectively; there was a substitution of phenylalanine in CMY-5 for isoleucine 105 in CMY-2. blaCMY-5 was followed by the Blc and SugE genes of C. freundii, and this cluster exhibited a genetic organization identical to that of the ampC region on the chromosome of C. freundii; these results confirmed that C. freundii AmpC was the evolutionary origin of the plasmidic cephamycinases. In the K. oxytoca host, the copy number of pTKH11 was very low and the plasmid coexisted with plasmid pNBL63. Analysis of the replication regions of the two plasmids revealed 97% sequence similarity in the RNA I transcripts; this result implied that the two plasmids might be incompatible. Incompatibility of the two plasmids might explain the cryptic phenotype of blaCMY-5 in K. oxytoca through an exclusion effect on pTKH11 by resident plasmid pNBL63.

Abstract
A 2.4-kb EcoRI fragment including the replication and origin of transfer regions of the Klebsiella pneumoniae multiresistance plasmid pJHCMW1 has been cloned and sequenced. The isolated replication region was sufficient for stable maintenance of the plasmid and shares homology with RNA-regulated replicons. Homology was highest with the replication region of the plasmid p15A. Incompatibility experiments, however, determined that pJHCMW1 is compatible with pACYC177, a plasmid harboring the p15A replicon. Differences in their RNA I nucleotide sequences may account for their compatibility. A mobilization origin was also found in the 2.4-kb EcoRI pJHCMW1 DNA fragment analyzed. Conjugation experiments showed that although non-self-transmissible, the recombinant clone including the 2.4-kb EcoRI pJHCMW1 fragment could be mobilized in the presence of the helper plasmid pRK2073.

Abstract
A non-self-transmissible multiple-copy plasmid, pEC3, isolated from the phytopathogenic bacterium, Erwinia carotovora subsp. carotovora, can be mobilized by an IncP-type plasmid. The hybrid plasmid vector, pETC3, constructed from pEC3 by fusion to markers conferring TcR and CmR, was transferred by conjugation from Escherichia coli (Ec) to various genera of Enterobacteriaceae and to other genera of Gram(-) bacteria which included Xanthomonas, Agrobacterium and Rhizobium. Deletion analysis and successive subcloning of pEC3 revealed that a cis-acting locus, oriT and a trans-acting locus, mob, were involved in mobilization of pEC3. Five open reading frames (ORFs) were found in the mob region, of which four were identified as mobA, B, C and D. The mobA gene overlapped with mobC, B, D and ORF1 that were transcribed polycistronically from upstream from mobC. The nature of the four products of mob genes, MobA, B, C and D, was verified by use of the T7 promoter system in Ec.
