stay, Patient A received successively piperacillin/tazobactam with vancomycin, cefepime with ciprofloxacin, and imipenem with ciprofloxacin, but Patient B only received amoxicillin/clavulanate (Figure 1). It is well established that K. pneumoniae isolates are an important reservoir of b-lactamases. Thus, the dissemination of the KPC carbapenemase has been linked to the dispersion of a clonal ST...

To prevent the spread of carbapenemase-producing bacteria, a fast and accurate detection of patients carrying these bacteria is extremely important. The Check-Direct CPE assay (Check-Points, Wageningen, The Netherlands) is a new multiplex real-time PCR assay, which has been developed to detect and differentiate between the most prevalent carbapenemase genes encountered in Enterobacteriaceae (bl...

The depletion of blaKPC (K. pneumoniae), blaOXA-50 (P. aeruginosa) and mecA (S. aureus) genes from hospital urines is evaluated to contribute solve the silent pandemic antibiotic-resistance bacteria. A microfluidic flow-through reactor with MMO anode CB/PTFE cathode working at 50 m−2 employed during electrodisinfection photo-electrodisinfection processes. process only achieves an almost negligi...

The genus Acinetobacter comprises 47 characterised genomic species, among which species belonging to the Acinetobacter calcoaceticus–Acinetobacter baumannii complex are the most clinically relevant. Within this complex, A. baumannii, Acinetobacter nosocomialis (formerly genomic species 13TU) and Acinetobacter pittii (formerly genomic species 3) are frequently associated with hospital-acquired i...

Acinetobacter johnsonii rarely causes human infections. While most A. johnsonii isolates are susceptible to virtually all antibiotics, strains harboring a variety of β-lactamases have recently been described. An A. johnsonii Aj2199 clinical strain recovered from a hospital in Buenos Aires produces PER-2 and OXA-58. We decided to delve into its genome by obtaining the whole genome sequence of th...

Acinetobacter baumannii is an important nosocomial pathogen, commonly causing infections in immunocompromised patients. It is increasingly reported as a multidrug-resistant organism, which is alarming because of its capability to resist all available classes of antibiotics including carbapenems. The aim of this study was to examine the genetic and epidemiological diversity of A. baumannii isola...

Resistance to various antimicrobial agents is an increasing problem in Pseudomonas aeruginosa and Acinetobacter baumannii infections. In this study, the roles of integrons were examined in 101 P. aeruginosa isolates and 176 A. baumannii isolates from patients. The frequencies and characteristics of class 1, 2 and 3 integrons were investigated and the horizontal transfer of integrons was assesse...

From late 2003 to the end of 2005, the Health Protection Agency's national reference laboratories received approximately 1,600 referrals of Acinetobacter spp., including 419 and 58 examples, respectively, of two carbapenem-resistant Acinetobacter baumannii lineages, designated OXA-23 clones 1 and 2. Representatives of these clones were obtained from 40 and 8 hospitals, respectively, in London o...

Carbapenem-resistant Acinetobacter baumannii have emerged globally. The objective of this study was to investigate the epidemiology, clonal diversity and resistance mechanisms of imipenem non-susceptible A. baumannii isolates in France. Between December 2010 and August 2011, 132 notifications were collected, including 37 outbreaks corresponding to 242 cases (2 to 55 per cluster). Multilocus seq...

Introduction: Infections caused by carbapenem-resistant Acinetobacter baumannii(CRAB) is a health problem due to the limited therapeutic options available. This study was carried out evaluate main mechanisms of resistance carbapenems in CRAB last 10 years Brazil and describe susceptibility profile tigecycline polymyxins these isolates. Material methods: A systematic review according Prisma PUBM...
