BACKGROUND The number of reported cases, infected with carbepenem resistant Acinetobacter baumannii (CRAb) and multi-drug resistant (MDR) Acinetobacter species had gradually increased in most PLA general hospital wards from April to June in 2007. OBJECTIVES We have described the investigation of an outbreak of CRAb and MDR Acinetobacter in PLA general hospital, Beijing. The prospective and re...

The adeH and adeS Efflux Pump Genes in Imipenem Colistin-Resistant Acinetobacter baumannii Clinical Isolates

BACKGROUND Multidrug-resistant (MDR) Acinetobacter spp. acquire antimicrobial agent-resistance genes via class 1 integrons. In this study, integrons were characterized to investigate the antimicrobial resistance mechanisms of MDR Acinetobacter isolates. In addition, the relationship between the integron type and integron-harboring bacterial species was analyzed by using epidemiological typing m...

BACKGROUND AND OBJECTIVES Acinetobacter causes a wide variety of illness in debilitated and hospitalized patients. Carbapenem resistance in Acinetobacter is an emerging problem and is a cause of concern as many nosocomial infections with Acinetobacter are resistant to most other antibiotics. The present study was aimed to study metallo-β-lactamase (MBL) production in Acinetobacter species. MA...

Acinetobacter; Nosocomial infections; Multi-drug resistance; Epidemiology; Characteristics Abstract The genus Acinetobacter is a major cause of nosocomial infections; it is increasingly being associated with various epidemics and has become a widespread concern in a variety of hospitals worldwide. Multi-antibiotic resistant Acinetobacter baumannii, is now recognized to be of great clinical sign...

Multiple antibiotic resistance threatens successful treatment of Acinetobacter baumannii infections worldwide. Increasing interest in the well-known activity of sulbactam against the genus Acinetobacter has been aroused. The purpose of this study was to compare the outcomes for patients with Acinetobacter bacteremia treated with cefoperazone/sulbactam versus imipenem/cilastatin. Forty-seven pat...

The aim of the present study was to examine the clinical distribution and drug resistance of Acinetobacter baumannii infection, and provide evidence of clinical medication as well as the prophylaxis for the treatment of drug resistance bacteria. In total, 306 Acinetobacter baumanniis selected from routine culture were collected between January 2012 and December 2013, to analyze the distribution...

Multidrug resistant among Acinetobacter baumannii infection is associated with a high mortality rate and limits the therapeutic options. The aim of this study was to assess the safety and efficacy of colistin monotherapy vs. other single antibiotic therapy AND colistin-based combination therapy (with other antibiotics) vs. colistin alone for the treatment of Acinetobacter baumannii infection. O...

Acinetobacter is a Gram-negative coccobacillus that is strictly aerobic, nonmotile, catalase positive and oxidase negative. It is ubiquitous in nature, being found in soil and water. Members of the genus Acinetobacter have now clearly emerged as opportunistic nosocomial pathogens (Forster et al., 1998). Bacteremia, pneumonia, meningitis, urinary tract and surgical wound infections are the most ...

BACKGROUND Members of the Acinetobacter calcoaceticus-baumannii (Acb) complex are important opportunistic bacterial pathogens and present significant therapeutic challenges in the treatment of nosocomial infections. In the present study, we investigated the integrons and various genes involved in resistance to carbapenems, aminoglycosides, and fluoroquinolones in 56 imipenem-nonsusceptible Acb ...
