L-lysine potentiates aminoglycosides against Acinetobacter baumannii via regulation of proton motive force and antibiotics uptake

Emerging Microbes and Infections, 2020
Acinetobacter baumannii, a Gram-negative opportunistic pathogen, is a leading cause of hospital- and community-acquired infections. Acinetobacter baumannii can rapidly acquire diverse resistance mechanisms and undergo genetic modifications that confer ...

Promising Prodiginins Biological Activities

Chemistry &Biodiversity, EarlyView.
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

adeABC efflux gene in Acinetobacter baumannii

New Microbes and New Infections, 2019
The antimicrobial resistance to Acinetobacter baumannii is significantly high and continues to grow; it has become a global health issue, particularly in regards to carbapenem resistance. The expression of efflux pumps is one of the major mechanisms of antibiotic resistance in A.

Ventilator-associated Acinetobacter baumannii pneumonia [PDF]

Indian Pediatrics, 2011
We report an outbreak of ventilator-associated pneumonia caused by carbapenem-resistant Acinetobacter baumannii in 6 infants with acute lower respiratory tract infection. Non-bronchoscopic bronchoalveolar lavage isolated A. baumannii in all these infants.

Molecular epidemiology of Acinetobacter baumannii during COVID-19 at a hospital in northern China

Annals of Clinical Microbiology and Antimicrobials
Background The wide spread of carbapenem-resistance clones of Acinetobacter baumannii has made it a global public problem. Some studies have shown that the prevalence of Acinetobacter baumannii clones can change over time.

The Response of Acinetobacter baumannii to Zinc Starvation [PDF]

Cell Host & Microbe, 2016
Zinc (Zn) is an essential metal that vertebrates sequester from pathogens to protect against infection. Investigating the opportunistic pathogen Acinetobacter baumannii's response to Zn starvation, we identified a putative Zn metallochaperone, ZigA, which binds Zn and is required for bacterial growth under Zn-limiting conditions and for disseminated ...
