[Electrical storm in patients with Automatic Implantable Defibrillator : A single Center study].

Background: Electrical storms (ES) are serious cardiac emergencies associated with increased short-term mortality. The true incidence of ES in patients with an implantable cardioverter defibrillator (ICD) is still difficult to estimate because of the heterogeneous definition. The clinical presentation is variable and its management is multidisciplinary.

Characterization of two polyvalent phages infecting Enterobacteriaceae.

Bacteriophages display remarkable genetic diversity and host specificity. In this study, we explore phages infecting bacterial strains of the Enterobacteriaceae family because of their ability to infect related but distinct hosts. We isolated and characterized two novel virulent phages, SH6 and SH7, using a strain of Shigella flexneri as host bacterium.

Characterization of Five Podoviridae Phages Infecting Citrobacter freundii.

Citrobacter freundii causes opportunistic infections in humans and animals, which are becoming difficult to treat due to increased antibiotic resistance. The aim of this study was to explore phages as potential antimicrobial agents against this opportunistic pathogen. We isolated and characterized five new virulent phages, SH1, SH2, SH3, SH4, and SH5 from sewage samples in Tunisia.
