We present a UBV CCD photometric study of four open clusters, NGC 7245, King 9, IC 166 and King 13, located between l = 90◦ and 135◦. All are embedded in a rich Galactic field. NGC 7245 and King 9 are close together in the sky and have similar reddenings. The distances and ages are: NGC 7245, 3.8 ± 0.35 kpc and 400 Myr; King 9 (the most distant cluster in this quadrant), 7.9 ± 1.1 kpc and 3.0 G...

In a 2008-2011 survey, 17,945 patients in 18 hospital units in Europe and Israel were screened for carriage of Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae, resulting in identification of 124 positive patients. The isolates were dominated by Klebsiella pneumoniae sequence type 258 (ST258) KPC-2 and ST512 KPC-3, mainly from Greece and Italy, respectively, whereas Israel...

Three selective chromogenic culture media (CHROMagars ESBL, CTX-M and KPC) were evaluated for their ability to support the growth of nine Klebsiella pneumoniae isolates producing OXA-48 carbapenemase in combination with other β-lactamases. CHROMagar ESBL and CHROMagar KPC were the most sensitive media, supporting growth of all isolates with a detection limit as low as < 100 CFU/ml. Five isolate...

The aim of this study was to unravel the genetic determinants responsible for multidrug (including carbapenems) resistance and virulence in a clinical isolate of Klebsiella quasipneumoniae subsp. similipneumoniae by whole-genome sequencing and comparative analyses. Eighty-three clinical isolates initially identified as carbapenem-resistant K. pneumoniae were collected from nosocomial infections...

Due to the lack of detailed reports of Klebsiella pneumoniae carbapenemase (KPC)-producing enterobacteria in Ontario, Canada, we perform a molecular characterization of KPC-producing Enterobacteriaceae submitted to the provincial reference laboratory from 2008 to 2011. Susceptibility profiles were accessed by E-test. Molecular types of isolates were determined by pulse-field gel electrophoresis...

BACKGROUND AND OBJECTIVES Klebsiella pneumoniae is an opportunistic pathogen responsible for up to 10% of nosocomial infections. The emergence and spread of multidrug resistant K. pneumoniae, mostly due to the production of extended-spectrum β-lactamases (ESBL) and carbapenemases, is often responsible for antibiotic treatment failure of these infections. We compared the antibiotic resistance pr...

Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae strains have spread worldwide and become a significant public health threat. blaKPC, the plasmid-borne KPC gene, was frequently identified on numerous transferable plasmids in different incompatibility replicon groups. Here we report the complete nucleotide sequence of a novel blaKPC-3-harboring IncI2 plasmid, pBK15692, isolated ...

Tidal radii of remote globular clusters (RGC > 35 kpc) are used to provide constraints of the mass profile of the Milky Way galaxy that are independent of kinematic data. The available data are consistent with the profile of an isothermal sphere with circular velocity Vc = 220 ± 40 km/s in the radial range 35 kpc 6 RGC 6 100 kpc, in good agreement with all recent estimates. The more robust cons...

OBJECTIVES To investigate the β-lactamase background of ertapenem non-susceptible isolates for the presence of the most commonly detected carbapenemase genes, bla(KPC), bla(OXA-48) and bla(VIM), and the newly described bla(NDM-1). METHODS Two hundred and thirty-five ertapenem-non-susceptible (MIC ≥ 0.5 mg/L) isolates of Enterobacteriaceae from the worldwide Study for Monitoring Antimicrobial ...

This study reveals the presence of different carbapenemase genes (blaKPC, blaNDM, blaGES, and blaOXA48-like genes) detected directly from water samples and clonal dispersion (by pulsed-field gel electrophoresis [PFGE] and multilocus sequence typing [MLST]) of KPC-2-producing Enterobacteriaceae in two important urban aquatic matrixes from Rio de Janeiro, Brazil, highlighting the role of aquatic ...
