Abstract

Klebsiella pneumoniae is a bacterial pathogen that has developed resistance to multiple antibiotics and is a major cause of nosocomial infections worldwide. Carbapenemase-producing Klebsiella pneumoniae have been isolated in many hospitals in Venezuela, but they have not been well-studied. The aim of this study was to characterize carbapenem-resistant Klebsiella pneumoniae isolates from the pediatric service of a hospital located in Anzoategui State, in the eastern part of Venezuela. Nineteen Klebsiella pneumoniae strains isolated in the hospital from April to July 2014 were evaluated phenotypically and molecularly for the presence of carbapenemases blaKPC, blaIMP and blaVIM. Molecular epidemiology was performed with Repetitive Extragenic Palindromic-PCR (REP-PCR) and Multilocus Sequence Typing (MLST). They were also studied for phenotypic and molecular resistance to a quaternary ammonium compound (QAC) disinfectant. All 19 isolates contained both bla VIM-2 and bla KPC-2 genes, and the bla KPC-2 gene was associated with Tn4401b. All isolates were phenotypically sensitive to QACs and contained qacΔE and addA2 genes typical of class 1 integrons. Analysis by REP-PCR and MLST showed that all isolates had identical profiles characteristic of sequence type ST833. All 19 strains are bla VIM-2 and bla KPC-2-producing ST833 K. pneumoniae sensitive to QACs. This analysis may help to understand the routes of dissemination and confirms that QAC disinfectants can be used to help control their spread.

Attention Score in Context

This research output has an Altmetric Attention Score of 2. 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 31 May 2017.
All research outputs
#6,476,455
of 11,379,716 outputs
Outputs from BMC Infectious Diseases
#1,913
of 4,230 outputs
Outputs of similar age
#119,835
of 252,995 outputs
Outputs of similar age from BMC Infectious Diseases
#88
of 231 outputs
Altmetric has tracked 11,379,716 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,230 research outputs from this source. They receive a mean Attention Score of 4.1. This one has gotten more attention than average, scoring higher than 54% of its peers.
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 252,995 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
We're also able to compare this research output to 231 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
