The genus Acinetobacter is comprised of a diverse group of species, several of which have raised interest due to potential applications in bioremediation and agricultural purposes. In this work, we show that many species within the genus Acinetobacter possess the genetic requirements to assemble a functional type VI secretion system (T6SS). This secretion system is widespread among Gram negativ...
BACKGROUND NXL104 potentiates ceftazidime and ceftaroline against Enterobacteriaceae with extended-spectrum, AmpC, KPC and OXA β-lactamases. We examined whether similar potentiation was obtained against non-fermenters, which are less permeable than Enterobacteriaceae and have more potent efflux. METHODS MICs of ceftazidime+NXL104 (with NXL104 at 4 mg/L) and comparators were determined by CLSI...
BACKGROUND The objective of this study was to investigate the distribution and susceptibility of aerobic and facultative Gram-negative bacilli isolated from Chinese patients with UTIs collected within 48 h (community acquired, CA) or after 48 h (hospital acquired, HA) of hospital admission. METHODS From 2010 to 2014, the minimum inhibitory concentrations (MICs) of 12 antibiotics for 4,332 aer...
BACKGROUND The Acinetobacter species, particularly A. baumannii, has emerged as one of the main causes of nosocomial infections in recent years. The high prevalence of drug resistance in A. baumannii limits the therapeutic options for treating infections caused by these bacteria. The objective of this study was to determine the in vitro activity of Tigecycline and Colistin against clinical isol...
conclusions the present study showed that bla oxa-23-like was the most frequent carbapenemase identified among carbapenem-resistant a. baumannii isolated in tehran hospitals. evaluation of antibiotic resistance genes in a. baumannii, is necessary to control further dissemination of these antibiotic resistant genes. results results showed that 123 of 131 (93.89%) acinetobacter species, possessed...
The burden of multidrug resistance in Gram-negative bacilli (GNB) now represents a daily issue for the management of antimicrobial therapy in intensive care unit (ICU) patients. In Enterobacteriaceae, the dramatic increase in the rates of resistance to third-generation cephalosporins mainly results from the spread of plasmid-borne extended-spectrum beta-lactamase (ESBL), especially those belong...
PURPOSE Nosocomial infections caused by Acinetobacter species is of increasing concern in critically ill patients, and the risk factors for this infection are not well established. The present investigation was done to determine incidence of nosocomial Acinetobacter infections. Our study retrospectively attempts to find risk and prognostic factors for the nosocomial acquisition of Acinetobacter...
Background: Acinetobacter baumannii has emerged as an important pathogen globally in various infections especially in hospital acquired infections. Objectives: This study was conducted to determine the prevalence, risk factors, and antibiotic resistance pattern of Acinetobacter baumannii from various clinical samples. Materials and Methods: The study included a total of 4269 clinical samples, c...
BACKGROUND Acinetobacter baumannii is an opportunistic pathogen posing an increased risk to hospitalized persons, causing nosocomial pneumonias, urinary tract infections and postoperative infections. METHODS Between 1 December 2011 and 30 September 2012, strains of Acinetobacter spp. were isolated from clinical samples obtained from hospitalized patients. Susceptibility to antibiotics was det...
