BACKGROUND Escherichia coli that produce extended-spectrum beta-lactamases (ESBLs) are an increasing cause of healthcare-associated infection, and community healthcare facilities may be a reservoir for important epidemic clones. AIM To characterize retrospectively and investigate the epidemiology of ESBL-producing E. coli collected in a Dublin hospital, during 2009 and 2010, and to investigat...

Good heuristic solutions for large Multisource Weber problems can be obtained by solving related p-median problems in which potential locations of the facilities are users locations and then solving Weber problems for the sets of users of each facility. Weber's problem is to locate a facility in the Euclidean plane in order to minimize the sum of its (weighted) distances to the locations of a g...

OBJECTIVES To determine factors associated with CTX-M-producing ST131 Escherichia coli which is the worldwide predominant lineage among CTX-M-producing E. coli isolates. METHODS Consecutive inpatients with a clinical sample positive for CTX-M-producing E. coli and considered as cases in a previous 8-month (2008-2009) case-control study performed in ten university hospitals in the Paris area w...

1. Introduction Icon is a high-level programming language that features facilities for string and list processing. In addition to these facilities, it has expressions, called generators, that are capable of producing sequences of results. A goal-directed evaluation mechanism automatically produces the results of generators in an attempt to produce 'successful' computations. Generators and goal-...

Infections with carbapenem-resistant Enterobacteriaceae (CRE) are increasing among patients in medical facilities. CRE that produce Klebsiella pneumoniae carbapenemase (KPC) have been responsible for much of the increase in the United States. However, New Delhi metallo-β-lactamase (NDM)-producing CRE have the potential to add to this burden. Since first reported in 2009, through 2012, 27 patien...
