BACKGROUND Extensively drug-resistant (XDR) Enterobacteriaceae carrying the bla(KPC) gene have emerged as a major global therapeutic concern. The purpose of this study was to analyze the complete sequences of plasmids from KPC-2 carbapenemase-producing XDR Escherichia coli sequence type (ST) 1642 isolates. METHODS We performed antimicrobial susceptibility testing, PCR, multilocus sequence typ...
OBJECTIVES Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae has spread rapidly in China. In this study, we aimed to investigate the molecular epidemiology of KPC-producing K. pneumoniae isolates in China. METHODS Ninety-five carbapenem-resistant K. pneumoniae isolates from 13 hospitals in nine cities covering five provinces in China were analysed. Antibiotic susceptib...
This report describes the epidemiological features of the first outbreak caused by KPC3 carbapenemase-producing Klebsiella pneumoniae (KPC-3-KP) in Spain and how it was effectively controlled. From 16 September 2009 to the end of February 2010, seven patients infected or colonised with KPC-3-KP were detected. Stool surveillance cultures were recovered from patients, doctors, nurses, nursing ass...
In the genome of Klebsiella pneumoniae NTUH-K2044, nine fimbrial gene clusters were identified. Besides type 1 and type 3 fimbriae, the others are novel and were named Kpa, Kpb, Kpc, Kpd, Kpe, Kpf and Kpg fimbriae. Prevalence analysis among 105 K. pneumoniae clinical isolates revealed that the kpc genes were highly associated with the K1 serotype isolates. Induced expression of the recombinant ...
The origin of gas falling from the halo toward the disk of the Milky Way is still largely unclear. Here the amount of gas shed by the (older) halo red giants is estimated. The distribution of red giants (RGs) in the halo is not known but that of a subset of stars in the post RG phase, the sdB stars of the horizontal-branch (HB), is. Using the mid-plane density and z-distribution of sdB stars, t...
The highand intermediate-velocity interstellar clouds (HVCs/IVCs) are tracers of energetic processes in and around the Milky Way. Clouds with near-solar metallicity about 1 kpc above the disk trace the circulation of material between disk and halo (the Galactic fountain). TheMagellanic Stream consists of gas tidally extracted from the SMC, tracing the dark matter potential of the Milky Way. Sev...
We present a sample of 218 new quasar pairs with proper transverse separations Rprop < 1 h −1 Mpc over the redshift range 0.5 < z < 3.0, discovered from an extensive follow up campaign to find companions around the Sloan Digital Sky Survey and 2dF Quasar Redshift Survey quasars. This sample includes 26 new binary quasars with separations Rprop < 50 h −1 kpc (θ < 10), more than doubling the numb...
A Chandra observation of the non-cooling flow cluster A 1060 has confirmed that the hot intracluster medium has fairly uniform distributions of temperature and metal abundance from a radius of about 230 kpc to the central 5 kpc region (H0 = 75 km s −1 Mpc). The radial temperature profile shows a broad peak at 30–40 kpc from the center at a level ∼ 20% higher than that in the outer region. Assum...
Background. High prevalence of Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae has been reported in long-term acute care hospitals (LTACHs), in part because of frequent readmissions of colonized patients. Knowledge of the duration of colonization with KPC is essential to identify patients at risk of KPC colonization upon readmission and to make predictions on the effects...
