Neisseria meningitidis is a leading etiologic agent of severe invasive disease. The objective of the study was to characterise invasive meningococcal disease (IMD) epidemiology in Poland during the last decade, based on laboratory confirmed cases.
Thirty-eight AmpC-producing Klebsiella pneumoniae isolates identified from January to October 2006 in a large teaching hospital in the Czech Republic were analyzed. The AmpC cephalosporinase was identified as DHA-1, encoded by a plasmid-located complex class 1 integron, previously observed in a K. pneumoniae isolate from the Parisian region. The DHA-1 expression was inducible, and although in two isolates with higher resistance, the induction effect was masked at the phenotypic level. All of the isolates belonged to the international K. pneumoniae clone sequence type 11, split into two disseminated pulsed-field gel electrophoresis types. This is the first report on enterobacteriaceae with acquired AmpCs in the Czech Republic and possibly the first description of organisms with DHA-1 in the Central and Eastern Europe.

What is Visualize?
JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.
How does it work?
We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.
Video X seems to be unrelated to Abstract Y...
In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
