Diversity of acinetobacter baumannii isolates from Egypt
Acinetobacter baumannii is an important nosocomial pathogen, frequently associated with morbidity and mortality in immunocompromised patients due to the immuno-ablative treatments, neutropenia and prolonged hospitalization. The ability of A. baumannii to survive in the healthcare setting makes it a …

Characterization of two component systems of Acinetobacter baumannii.
Acinetobacter baumannii is an important opportunistic pathogen of hospital acquired infection, particularly in intensive care units. The emergence and rapid spread of multidrug-resistant A. baumannii strains has become a major health threat worldwide which severely limits the treatment options for …

Investigation of a Heme Uptake System in Acinetobacter baumannii
… heme acquisition in the opportunistic pathogen, Acinetobacter baumannii, are examples of such pathways requiring further characterization. This is especially important as A. baumannii is an increasing threat to global health due to its extensive antibiotic resistance. In this thesis, I show that …

Laboratory evolution and natural transformation in Acinetobacter baylyi ADP1
The bacterium Acinetobacter baylyi ADP1 has been proposed as a next-generation chassis for genome engineering due to its high natural transformation rates and metabolic proficiency. Development of ADP1 for biotechnological use however is inhibited by the evolutionary instability of the competence, …

Investigating Iron Transport and Utilization Features of Acinetobacter baumannii
<i>Acinetobacter baumannii</i> is an important opportunistic human pathogen that causes severe nosocomial infections. The bacterium must overcome iron starvation and oxidative stress conditions imposed by the host in order to propagate and cause disease. This work further investigates the transport …

Analysis of resistance nodulation division efflux pumps in Acinetobacter baumannii
Strains from Canadian hospitals were classified as A. baumannii, A. pitti, or A. osocomialis and the most commonly expressed resistance nodulation division (RND) efflux pump was adeFGH. A collection of A. baumannii isolates from the environment showed decreased susceptibility to at least three …

Pediculus humanus capitis as a potential vector for Acinetobacter baumannii
… Europe, Asia, and Africa coincide in reporting Acinetobacter baumannii, a known opportunistic bacterium causing frequent health-care associated outbreaks. No reports from countries in South America have been published and is important to confirm whether this pathogen is also present in head lice …

The genetic location and regulation of aminoglycoside resistance genes in acinetobacter
… resistance in clinical isolates of Acinetobacter was investigated. The aadB genes cloned from two clinical isolates, strain CHA and strain SUN, were sequenced. Analysis of the sequencing data indicated that both genes were contained on gene cassettes, which had integrated at …

Uncovering Mechanisms of Cell Envelope Integrity and Nutrient Acquisition in Acinetobacter baumannii
Acinetobacter baumannii is an emerging bacterial pathogen of critical concern due to increasing multidrug resistance. The outer membrane (OM) of A. baumannii is a key barrier to antimicrobials and stressors but must also allow the entry of essential nutrients. The maintenance of lipid asymmetry …

The location, expression and regulation of three antibiotic resistance genes in acinetobacter
Clinical isolates of Acinetobacter often exhibit resistance to many antibiotics, including the aminoglycosides and chloramphenicol. Yet very little is known about this resistance at the molecular level. A strain of Acinetobacter baumannii (strain SAK) was isolated from a tracheal aspirate; it is …
