Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Bacterial Genome Wide Association Studies (bGWAS) and Transcriptomics Identifies Cryptic Antimicrobial Resistance Mechanisms in Acinetobacter baumannii

Frontiers in Public Health, 2020
Antimicrobial resistance (AMR) in the nosocomial pathogen, Acinetobacter baumannii, is becoming a serious public health threat. While some mechanisms of AMR have been reported, understanding novel mechanisms of resistance is critical for identifying ...

Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, EarlyView.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

Evaluation of the Sensitivity of Acinetobacter sp. burn isolates to Ciprofloxacin and some of other used antibiotics for treatment

فصلنامه دانشگاه علوم پزشکی جهرم, 2009
Introduction: Acinetobacter sp. is usually considered to be opportunistic pathogens.  They are often multi-resistant to antibiotics, meaning that therapy and infection control are complicated.

Acinetobacter infections: Overview and treatment dilemma

CHRISMED Journal of Health and Research, 2020
Introduction: Acinetobacter species are known to cause serious hospital-acquired infections (HAIs), especially in the intensive care unit (ICU). The aim of this study is to estimate the burden of such infections and also to determine their sensitivity to

Identification of a Pair of Linear or Cyclic Naturally Inspired Bifunctional Lipopeptide Antibiotics That Overcome Antimicrobial Resistance

Advanced Science, EarlyView.
The underexplored bacterial genus Aquimarina harbors a large biosynthetic potential for discovering new antibiotics. Here, the authors identify a pair of linear or cyclic bifunctional cationic lipopeptide antibiotics, aquicidine L and C4, inspired by the aquicidine gene cluster from Aquimarina.

Acinetobacter pollinis sp. nov., Acinetobacter baretiae sp. nov. and Acinetobacter rathckeae sp. nov., isolated from floral nectar and honey bees.

International Journal of Systematic and Evolutionary Microbiology, 2021
A detailed evaluation of eight bacterial isolates from floral nectar and animal visitors to flowers shows evidence that they represent three novel species in the genus Acinetobacter. Phylogenomic analysis shows the closest relatives of these new isolates
