Abstract
OBJECTIVES To characterize VIM-type metallo-β-lactamase (MBL)-encoding genomic islands (GIs) in Pseudomonas aeruginosa and P. putida group isolates from Polish hospitals from 2001-2015/16. METHODS Twelve P. aeruginosa and 20 P. putida group isolates producing VIM-like MBLs were selected from a large collection of these based on epidemiological and typing data. The organisms represented all major epidemic genotypes of these species spread in Poland with chromosomally located blaVIM gene-carrying integrons. The previously determined short-read sequences were complemented by long-read sequencing in this study. The comparative structural analysis of the GIs used a variety of bioinformatic tools. RESULTS Thirty different GIs with blaVIM integrons were identified in the 32 isolates, of which 24 GIs from 26 isolates were integrative and conjugative elements (ICEs) of the clc family. These in turn were dominated by 21 variants of the GI2/ICE6441 subfamily with a total of 19 VIM integrons, each inserted in the same position within the ICE's Tn21-like transposon Tn4380. The three other ICEs formed a novel ICE6705 subfamily, lacking Tn4380 and having different VIM integrons located in another site of the elements. The remaining six non-ICE GIs represented miscellaneous structures. The presence of various integrons in the same ICE sublineage, and of the same integron in different GIs, indicated circulation and recombination of the integron-carrying genetic platforms across Pseudomonas species/genotypes. CONCLUSIONS Despite the general diversity of the blaVIM-carrying GIs in Pseudomonas spp. in Poland, a clear predominance of broadly spread and rapidly evolving clc-type ICEs was documented, confirming their significant role in antimicrobial resistance epidemiology.

Abstract
PURPOSE To elucidate the role of the Klebsiella oxytoca species complex (KoSC) in epidemiology of VIM-type MBL-producing Enterobacterales in Poland. METHODS The study comprised all 106 VIM-positive KoSC isolates collected by the Polish National Reference Centre for Susceptibility Testing during 2009-2019 from 60 institutions in 35 towns. All isolates were sequenced by Illumina MiSeq, followed by MinION sequencing of selected organisms. Genomes were subjected to bioinformatic analysis, addressing taxonomy, clonality, phylogeny and structural characterisation of key resistance determinants within their chromosomal and plasmidic loci. RESULTS Among five species identified, K. oxytoca was predominant (n = 92), followed by Klebsiella michiganensis (n = 11). MLST distinguished 18 STs, with the most prevalent Klebsiella oxytoca ST145 (n = 83). The clone segregated a lineage with the In237-like integron [blaVIM-1-aacA4 genes; n = 78], recorded in 28 cities almost all over the country. The integron was located in a ~ 49-50 kb chromosomal mosaic region with multiple other resistance genes, linked to a ~ 51 kb phage-like element. The organism might have originated from Greece, and its evolution in Poland included several events of chromosomal ~ 54-258 kb deletions, comprising the natural β-lactamase blaOXY gene. A group of other isolates of various species and clones (n = 12) carried the integron In916 on self-transmissible IncA-type plasmids, effectively spreading in Italy, France and Poland. CONCLUSION KoSC has been one of the major VIM producers in Poland, owing largely to clonal expansion of the specific K. oxytoca-In237-like lineage. Its apparently enhanced epidemic potential may create a danger on international scale.

Abstract
OBJECTIVES To characterize carbapenemase-producing isolates of the Klebsiella pneumoniae hypervirulent (hvKp) clone ST23 in Poland. METHODS Fifteen K. pneumoniae ST23 isolates were identified by the Polish surveillance of carbapenemase-producing Enterobacterales. These comprised a cluster with KPC-2 + NDM-1 (n = 7), KPC-2 (n = 1) or NDM-1 (n = 1) enzymes from one hospital from 2018, and sporadic isolates with KPC-2 (n = 1), NDM-1 (n = 1), VIM-1 (n = 1) or OXA-48 (n = 3), recovered from 2009 to 2019 in different towns. The isolates were sequenced by Illumina MiSeq, followed by MinION for six representatives. Clonality, phylogeny, serotypes, virulomes, resistomes and plasmids of the isolates were analysed and compared with international ST23 strains, using various bioinformatic tools. RESULTS Only two diverse isolates with KPC-2 or VIM-1 were of typical hvKp ST23 serotypes K1 and O1v.2, and its predominant phylogenetic clade. These contained multiple chromosomal (ybt, clb) and pK2044/KpVP-1 plasmid (iuc, iro, rmpADC, rmpA2) virulence loci, whereas carbapenemase and other antimicrobial resistance (AMR) genes were on single additional plasmids. All remaining isolates were of K57 and O2v.2 serotypes, and a minor, distant clade of unclear phylogeny, including also ∼10 isolates from other European countries. These had fewer virulence loci (ybt, iuc, rmpADC, rmpA2) but abounded in plasmids, which with several chromosomal AMR mutations conferred more extensive MDR phenotypes than in K1 O1v.2. Lower clonal diversity than in K1, and numerous common characteristics of the isolates supported the hypothesis of the emerging character of the ST23 K57 clade. CONCLUSIONS A new MDR ST23 lineage has emerged in Europe, causing a potential threat to public health.

Abstract
OBJECTIVES To assess the spread of New Delhi metallo-β-lactamase-1 (NDM-1)-producing Klebsiella pneumoniae ST147 organisms in Poland since an introduction from Tunisia in March 2015, including their phylogenetic position in the global population of the high-risk clone. METHODS Out of 8925 unique NDM-positive K. pneumoniae isolates identified in Poland from April 2015 till December 2019, 126 isolates, including the Tunisian imports, were related by PFGE and blaNDM gene-carrying Tn125 transposon derivatives. Forty-seven representative isolates were sequenced by Illumina MiSeq. The phylogeny, resistome, virulome and plasmid replicons were analysed and compared with the international ST147 strains. Plasmids of six isolates were studied by the MinION sequencing. RESULTS A high homogeneity of the 47 isolates was observed, with minor variations in their resistomes and plasmid replicon profiles. However, the detailed SNP comparison discerned a strict outbreak cluster of 40 isolates. All of the organisms were grouped within the ST147 phylogenetic international lineage, and four NDM-1 producers from Tunisia, Egypt and France were the closest relatives of the Polish isolates. Yersiniabactin genes (YbST280 type) were located within the ICEKpn12-like element in most of the outbreak isolates, characterized by O2v1 and KL64 antigen loci. The blaNDM-1 genes were located in double-replicon IncFIIK2+IncFIBK plasmids. CONCLUSIONS The continuous spread of K. pneumoniae ST147 NDM-1 in Poland since 2015, largely in the Warsaw area, is demonstrated by this genomic analysis. The isolates showed a high degree of homogeneity, and close relatedness to organisms spreading in the Mediterranean region.

Abstract
OBJECTIVES To identify key factors of the expansion of metallo-β-lactamase (MBL)-producing Pseudomonas aeruginosa (MPPA) in Poland, focusing on the role of clonal epidemic(s). METHODS MPPA isolates were typed by PFGE, followed by MLST. blaVIM/IMP MBL genes were amplified and sequenced within class 1 integrons. Their location was assessed by S1 nuclease-hybridization assays. Short-read WGS was performed, and genomes were subjected to SNP-based phylogenetic and resistome analyses. RESULTS Of 1314 MPPA isolates collected in 2005-15 from 212 hospitals, 454 representatives were selected. The isolates belonged to 120 pulsotypes and 52 STs, of which ST235 (∼31%), ST111 (∼17%), ST273 (∼16%) and ST654 (∼9%) prevailed, followed by ST244, ST17, ST395, ST175 and ST1567. The isolates produced seven VIM variants (97.5%) and four IMPs encoded by 46 integrons, most of which were observed only or mainly in Poland. Around 60% of the isolates resulted from (inter)regional clonal outbreaks of 10 individual ST235, ST111, ST273 and ST654 genotypes. The phylogenetic analysis of 163 genomes revealed heterogeneity of ST235 and ST111 populations, arising from transnational circulation and on-site differentiation of several clades/branches. Contrarily, ST273 and ST654 formed relatively homogeneous and apparently Poland-specific lineages, and a unique ST273 genotype with integron In249 was the most expansive organism. CONCLUSIONS Together with a previous report on self-transmissible In461-carrying IncP-2-type plasmids, this study revealed the molecular/genomic background of the rapid MPPA increase in Poland in 2001-15, evidencing multi-clonal spread as its leading factor. Numerous novel/specific MPPA characteristics were identified.

Abstract
OBJECTIVES To characterize genomes of Klebsiella pneumoniae ST11 NDM-1 responsible for a countrywide outbreak in Poland and compare them phylogenetically with other Polish and international ST11 strains. METHODS Seventy-one carbapenemase-producing K. pneumoniae ST11 isolates from Poland, including 66 representatives of the NDM-1 epidemic from 2012-18, were sequenced using Illumina MiSeq. Additionally, three outbreak isolates were also sequenced using MinION. The clonality and phylogenetic analysis was done by core-genome MLST and SNP approaches. Resistomes, virulomes, K/O antigens and plasmid replicons were screened for. The detailed plasmid analysis was based on full assemblies using Oxford Nanopore Technologies data. RESULTS Chromosomes of the outbreak isolates formed an essentially homogeneous cluster (though accumulating SNPs gradually with time), differing remarkably from other Polish NDM-1/-5-, KPC-2- or OXA-48-producing K. pneumoniae ST11 strains. The cluster belonged to a clade with 72 additional isolates identified worldwide, including closely related NDM-1 producers from several countries, including organisms from Bulgaria and Greece. All these had KL24 and O2v1 antigens and the chromosomal yersiniabactin locus YbST230 residing in the ICEKp11 element. The specific blaNDM-1-carrying Tn125 transposon derivative, named Tn125A, was located in IncFII/pKPX-1- and/or IncR-like plasmids; however, the IncRs rearranged extensively during the outbreak, contributing to highly dynamic plasmid profiles and resistomes. CONCLUSIONS The K. pneumoniae ST11 NDM-1 genotype that has been expanding in Poland since 2012 is largely monoclonal and represents a novel international high-risk lineage that is also spreading in other countries.

Abstract
OBJECTIVES In 2015 and 2016 Poland recorded rapid proliferation of New Delhi MBL (NDM)-producing Enterobacterales, with at least 470 and 1780 cases, respectively. We addressed the roles of the Klebsiella pneumoniae ST11 NDM-1 outbreak genotype, already spreading in 2012-14, and of newly imported organisms in this increase. METHODS The study included 2136 NDM-positive isolates identified between April 2015 and December 2016, following transfer of patients with K. pneumoniae ST147 NDM-1 from Tunisia to Warsaw in March 2015. The isolates were screened by PCR mapping for variants of blaNDM-carrying Tn125-like elements. Selected isolates were typed by PFGE and MLST. NDM-encoding plasmids were analysed by nuclease S1/hybridization, transfer assays, PCR-based replicon typing and PCR mapping. RESULTS The organisms were mainly K. pneumoniae containing the Tn125A variant of the ST11 epidemic lineage (n = 2094; ∼98%). Their representatives were of the outbreak pulsotype and ST11, and produced NDM-1, encoded by specific IncFII (pKPX-1/pB-3002cz)-like plasmids. The isolates were recovered in 145 healthcare centres in 13/16 administrative regions, predominantly the Warsaw area. The 'Tunisian' genotype K. pneumoniae ST147 NDM-1 Tn125F comprised 18 isolates (0.8%) from eight institutions. The remaining 24 isolates, mostly K. pneumoniae and Escherichia coli of diverse STs, produced NDM-1 or NDM-5 specified by various Tn125 derivatives and plasmids. CONCLUSIONS The K. pneumoniae ST11 NDM-1 outbreak has dramatically expanded in Poland since 2012, which may bring about a countrywide endemic situation in the near future. In addition, the so-far limited K. pneumoniae ST147 NDM-1 outbreak plus multiple NDM imports from different countries were observed in 2015-16.

Abstract
Objectives To analyse OXA-48 (OXA-48/181)-type carbapenemase-producing Enterobacteriaceae reported in Poland from 2013 until January 2017. Methods Bacterial isolates were typed by PFGE and MLST. Genes coding for OXA-48/181 types and other β-lactamases were amplified and sequenced. Mobile elements with blaOXA-48/181-like genes were PCR mapped. blaOXA-48/181-carrying plasmids were characterized by nuclease S1-hybridization profiling, transfer assays and PCR-based replicon typing, while the chromosomal location of the genes was confirmed by the I-CeuI analysis. Results Fifty-four isolates from 52 patients in 20 hospitals (14 cities) were included, in 14 cases having probable foreign origins indicated. The organisms were genetically diverse and represented numerous pandemic clones, including Klebsiella pneumoniae ST395 (n = 23), ST11, ST15 and ST101, Escherichia coli ST38, ST410 and ST648, and Enterobacter cloacae complex ST78. These produced OXA-48 (n = 49), OXA-181 (n = 4) or OXA-232 (n = 1). One of five K. pneumoniae ST395 pulsotypes caused a multicentre outbreak with 18 cases, which significantly contributed to the total number of patients. Depending on the variant, the blaOXA-48/181-like genes were parts of the Tn1999-, Tn2013- or Tn2016-like transposons, with blaOXA-48 found in an ISEcp1-associated module (Tn2016-like) for the first time. Three genotypes, including E. coli ST38, had chromosomal blaOXA-48 genes, while others carried transmissible IncL (∼60 kb; blaOXA-48; n = 30), IncM (∼80-95 kb; blaOXA-48; n = 4), IncX3 (∼50 kb; blaOXA-181; n = 4) or non-typeable (∼90-160 kb; blaOXA-48 or blaOXA-232) plasmids. Conclusions Even though OXA-48/181 producers seem to occur infrequently in Poland, their epidemiology has been marked by various phenomena, namely multiple imports, several limited transmissions plus one larger clonal outbreak, and possible plasmid transfers.

Abstract
OBJECTIVES The objective of this study was to examine Klebsiella oxytoca clonal and phylogenetic diversity, based on an international collection of carriage isolates non-susceptible to expanded-spectrum cephalosporins (ESCs). METHODS The study material comprised 68 rectal carriage K. oxytoca isolates non-susceptible to ESCs recovered in 2008-11 from patients in 14 hospitals across Europe and Israel. ESC resistance was tested phenotypically; genes encoding ESBLs, AmpC cephalosporinases and carbapenemases were amplified and sequenced. The isolates were typed by PFGE and MLST, followed by sequencing of blaOXY genes. RESULTS MLST and PFGE distinguished 34 STs and 47 pulsotypes among the isolates, respectively. Six STs were split into several pulsotypes each. Five STs were more prevalent (n = 2-9) and occurred in several countries each, including ST2, ST9 and ST141, which belong to a growing international clonal complex (CC), CC2. Four phylogenetic lineages were distinguished, each with another type of chromosomal OXY-type β-lactamase. Three of these, with OXY-1/-5, OXY-2 types and OXY-4, corresponded to previously described phylogroups KoI, KoII and KoIV, respectively. A single isolate from Israel represented a distinct lineage with a newly defined OXY-7 type. The phylogroups showed interesting differences in mechanisms of ESC resistance; KoI strains rarely overexpressed the OXY enzymes but commonly produced ESBLs, whereas KoII strains often were OXY hyperproducers and carried ESBLs much less frequently. AmpCs (DHA-1) and carbapenemases (VIM-1) occurred sporadically. CONCLUSIONS The study confirmed the high genetic diversity of the collection of K. oxytoca ESC-non-susceptible isolates, composed of phylogroups with distinct types of OXY-type β-lactamases, and revealed some STs of broad geographical distribution.

Abstract
An alternative approach to the dielectric relaxation and resonance absorption is proposed. Two assumptions were taken into consideration. One, that there exists a dielectric in which particular molecules have different freedom of motion. The other, that the value of the motion damping coefficient can be described by the distribution function. The obtained formula for the description of the experimental data of dielectric relaxation and resonance absorption measurements is presented.
