The presence of pan-resistant bacteria worldwide possesses a threat to global health. It is difficult to evaluate the extent of carriage of resistant bacteria in the population. Sewage sampling is a possible way to monitor populations. We evaluated the presence of pan-resistant bacteria in Israeli sewage collected from all over Israel, by modifying the pour plate method for heterotrophic plate count technique using commercial selective agar plates. This method enables convenient and fast sewage sampling and detection...

Enterobacter cloacae is a clinically important Gram-negative member of the Enterobacteriaceae, which has increasingly been recognized as a major pathogen in nosocomial infections. Despite this, knowledge about the population structure and the distribution of virulence factors and antibiotic-resistance determinants of this species is scarce. In this study, we analysed a systematic collection of multidrug-resistant E. cloacae isolated between 2001 and 2011 from bloodstream infections across hospitals in the UK and Ireland...
