| Abstract |
Antimicrobial-resistant Klebsiella pneumoniae represent a global public health concern. K. pneumoniae strains isolated during 2010 and 2014-2016 within a single hospital of Molise Region, Central Italy, were analyzed testing antimicrobial susceptibility, clonality by pulsed-field gel electrophoresis (PFGE) and random amplified polymorphic DNA (RAPD)-PCR, and prevalence of carbapenem resistance genes by PCR. Forty isolates (23 wild-type in 2010 and 17 non-wild-type in 2014-2016) were collected from hospitalized patients (65.2 ± 18.1 years old, 75% male, 80% from intensive care unit-ICU). K. pneumoniae showed multidrug-resistant profiles and 15 resistotypes were identified (discriminatory power D = 0.88). The 69.6 and 17.4% of isolates in 2010 resulted intermediate and resistant to imipenem, respectively, and 91.3% was sensitive to meropenem, while 88.2% of isolates of 2014-2016 were resistant to both antibiotics. PFGE identified 16 clusters versus 23 by RAPD, 26 pulsotypes versus 33 RAPD patterns (D ≥ 0.97). PFGE separated strains according to isolation period and identified an outbreak occurred in the ICU during December 2014 and January 2015. No strains harbored blaGES, blaIMP, blaNDM-1, and blaOXA-48genes, as well as AmpC plasmid-mediated beta-lactamases genes. Only K. pneumoniae isolated during 2014-2016 were blaKPCpositive. Prevalence of blaVIMwas 87 and 76.5% during 2010 and 2014-2016, respectively. No strains colistin-resistant harbored mcr-1 plasmid-mediated resistance gene. The study findings underline an increased circulation of multidrug-resistant K. pneumoniae within the hospital, and the acquisition of carbapenem resistance mechanism. The implementation of surveillance and molecular characterization of isolates are needed to identify outbreaks, reduce the spread of resistance, and guide empirical therapy. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 March 2018.
All research outputs
#18,590,133
of 23,026,672 outputs
Outputs from Current Microbiology
#1,692
of 2,428 outputs
Outputs of similar age
#258,274
of 332,332 outputs
Outputs of similar age from Current Microbiology
#29
of 45 outputs
Altmetric has tracked 23,026,672 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,428 research outputs from this source. They receive a mean Attention Score of 3.2. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 332,332 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 45 others from the same source and published within six weeks on either side of this one. This one is in the 20th percentile – i.e., 20% of its contemporaries scored the same or lower than it.
