BACKGROUND The clinical and economic impact of multidrug-resistant (MDR) Acinetobacter baumannii colonization remains unclear. This study aimed to estimate and compare the mortality rates, length of stay (LOS), and hospitalization costs in the intensive care unit (ICU) for MDR A. baumannii colonized patients and a matched population. MATERIALS AND METHODS We performed a retrospective propensi...

Background and Aims: Acinetobacter baumannii is mostly a cause of septicaemia, pneumonia and urinary tract infections following hospitalization of patients with more severe illnesses. The aim of this study was to determine the prevalence and detection of the most prevalent virulence genes in A. baumannii isolated from hospital infections of two largest hospitals of Tehran, Iran. Materials and ...

BACKGROUND The adeB gene in Acinetobacter baumannii regulates the bacterial internal drug efflux pump that plays a significant role in drug resistance. The aim of our study was to determine the occurrence of adeB gene in multidrug resistant and New Delhi metallo-beta-lactamase-1 (NDM- 1) gene in imipenem resistant Acinetobacter baumannii isolated from wound swab samples in a tertiary care hospi...

Acinetobacter baumannii, an opportunistic ESKAPE pathogen, causes respiratory and urinary tract infections. Its prevalence increases gradually in the clinical setup. Pathogenicity of Acinetobacter is significantly influenced by its ability to infect and survive in human pulmonary cells. Therefore, it is important to study the infection of A. baumannii in human pulmonary host cell (A-549), monit...

background: this study aimed to evaluate the role of efflux pump regulator and oxa-23 genes in imipenem resistance acinetobacter baumannii strains isolated from hospitalized patients in tehran, iran. methods: this study was conducted on 60 a. baumannii isolates collected from patients admitted to the shahid motahari and taleghani hospitals in tehran during 2013-14. antibiotic susceptibility tes...

background and objective : carbapenems are therapeutic choice against infections caused by gram-negative bacilli including strains of acinetobacter baumannii. resistance to these antibiotics is mediated by efflux pumps, porins, pbps and ß-lactamases. the aim of this study was to determine the possibility of existence of mbls, oxas and ges-1 betalactamase genes among clinical isolates of acineto...

BACKGROUND Emerging carbapenem resistance among Acinetobacter baumannii clinical isolates is a worldwide problem. Infections caused by A. baumannii are increasing and demonstrate high mortality rates. This study aimed to establish a nationwide surveillance of antimicrobial susceptibility, carbapenemase genes, and clonal relationships of A. baumannii clinical isolates in Taiwan. METHODS Clinic...

Objective(s):Antibiotic resistance in Acinetobacter baumannii and outbreaks caused by this organism have been reported from several areas of the world. The present study aimed at determining the antibiotic susceptibility profiles and the distribution of OXA-type beta-lactamases among Iranian Acinetobacter baumannii isolates from Qom of Iran. Materials and Methods: For this study, 108 non-duplic...
