BACKGROUND Acinetobacter baumannii is an opportunistic pathogen, related with nosocomial infections such as bacteremia, urinary tract infections, and ventilator-associated pneumonia. Multidrug resistant (MDR) A. baumannii strains are first line causes of infection, especially in patients hospitalized at intensive care units (ICUs). Infection with MDR A. baumannii strains has a longer duration a...

the emergence of multidrug resistance (mdr) and extensively drug resistance (xdr) in acinetobacter baumannii has made an important challenge in the treatment of infections caused by this organism. the ability of carbapenemase production is one of the main mechanisms for the emergence of mdr and/or xdr in a. baumannii. the aim of this study was to detect carbapenemase producer a. baumannii. in t...

The objective of the study was to determine the effects of Candida albicans respiratory tract colonization on Acinetobacter baumannii pneumonia in a rat model. Rats were colonized with C. albicans by instillation of 3 × 10(6) CFU into their airways, while sterile saline was instilled in the control group. The colonized rats were further divided into two groups: treated with amphotericin B or no...

Background & Objective : Currently, Acinetobacter baumannii is an important nosocomial pathogen insofar as its hospital outbreaks have been described from various geographical areas. Since the discrimination of strains within a species is important for delineating nosocomial outbreaks, this study was conducted with the aim of genotyping the A. baumannii clinical strains in Tehran via the pulsed...

The worldwide dissemination of multi drug resistant Acinetobacter baumannii strains has caused serious concern and high rate of mortality in recent decades that originate from limited effective antibiotics in the treatment of A. baumannii infections. Myxobacteria are Gram-negative bacteria that are important for their complex lifestyle and production of novel structurally secondary metabolites ...

OBJECTIVES To determine the genomic sequence of extensively drug-resistant Acinetobacter baumannii DU202 and to perform proteomic characterization of antibiotic resistance in this strain using genome data. METHODS The genome sequence of A. baumannii DU202 was determined using the Hi-Seq 2000 system and comparative analysis was performed to determine the unique characteristics of A. baumannii ...

Many sequenced strains of Acinetobacter baumannii are established nosocomial pathogens capable of resistance to multiple antimicrobials. Community-acquired A. baumannii in contrast, comprise a minor proportion of all A. baumannii infections and are highly susceptible to antimicrobial treatment. However, these infections also present acute clinical manifestations associated with high reported ra...
