| Abstract |
Resistance to carbapenems is considered to represent a serious threat to public health at the global level, since these antibiotics are one of the last therapeutic options for the treatment of multidrug-resistant bacteria. Molecular characterization of outbreaks due to resistant bacteria provides information that can be used in the design of infection control strategies. To describe the molecular characteristics of an outbreak of carbapenem-resistant Klebsiella pneumoniae that occurred in a tertiary care hospital in Medellín in 2010-2011. Eighty-four isolates were obtained from a collection of strains associated with the hospital outbreak, of which 32 were from patients infected at that time and 52 were carriers. Identification and susceptibility of the isolates was performed using Vitek2 ® . Carbapenemases were detected using a modified Hodge test and polymerase chain reaction. Genetic relationships between the isolates were evaluated using pulsed field gel electrophoresis and multiple locus sequence typing. All the isolates analyzed were multidrug resistant; molecular analysis revealed that all harbored bla KPC-3 . The genetic analysis showed that 58/64 of the isolates from both infected and colonized patients were closely related (Dice similarity index >80%) and belonged to the ST258 lineage. Using molecular typing techniques it was possible to confirm the occurrence of an outbreak caused by K. pneumoniae ST258, a carrier of bla KPC-3 with a multidrug-resistant profile which had been associated with a previous outbreak in another hospital in the city of Medellín. ST258 is a high risk clone at the global level, demonstrating the potential for dissemination of resistance in this country. Implementation of molecular tools in support of epidemiological surveillance is useful for evaluating the spread of microorganisms of public health significance. |

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 26 February 2016.
All research outputs
#19,947,956
of 25,377,790 outputs
Outputs from Biomédica
#626
of 848 outputs
Outputs of similar age
#192,306
of 280,384 outputs
Outputs of similar age from Biomédica
#7
of 17 outputs
Altmetric has tracked 25,377,790 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 848 research outputs from this source. They receive a mean Attention Score of 3.8. 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 280,384 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 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 52% of its contemporaries.
