Pathogenic Acinetobacter species have a functional type I secretion system and contact-dependent inhibition systems
(American Society for Biochemistry and Molecular Biology, Inc., 2017-04-03)
Pathogenic Acinetobacter species, including Acinetobacter baumannii and Acinetobacter nosocomialis, are opportunistic human pathogens of increasing relevance worldwide. Although their mechanisms of drug resistance are ...

Immunization with Lipopolysaccharide-Deficient Whole Cells Provides Protective Immunity in an Experimental Mouse Model of Acinetobacter baumannii Infection
(2014)
The increasing clinical importance of infections caused by multidrug resistant Acinetobacter baumannii warrants the development of novel approaches for prevention and treatment. In this context, vaccination of certain ...

Synergistic Activity of Niclosamide in Combination With Colistin Against Colistin-Susceptible and Colistin-Resistant Acinetobacter baumannii and Klebsiella pneumoniae
(Frontiers Research Foundation, 2018-10-03)
Colistin is among the few antibiotics effective against multidrug-resistant Acinetobacter baumannii and Klebsiella pneumoniae clinical isolates. However, in the last few years, colistin-resistant A. baumannii and K. ...

Positive Predictive Value of Leeds Acinetobacter Medium for Environmental Surveillance of Acinetobacter baumannii
(American Society of Microbiology, 2011)
Infections caused by Acinetobacter baumannii often occur in outbreaks during which the bacteria are spread through contact with clinical personnel harboring the bacteria and from colonized hospital equipment (2). Environmental ...

Inhibition of LpxC Increases Antibiotic Susceptibility in Acinetobacter baumannii
(American Society for Microbiology, 2016-08)
LpxC inhibitors have generally shown poor in vitro activity against Acinetobacter baumannii. We show that the LpxC inhibitor PF-5081090 inhibits lipid A biosynthesis, as determined by silver staining and measurements of ...

Activity of Host Antimicrobials against Multidrug-Resistant Acinetobacter baumannii Acquiring Colistin Resistance through Loss of Lipopolysaccharide
(American Society for Microbiology, 2014-05)
Acinetobacter baumannii can acquire resistance to the cationic peptide antibiotic colistin through complete loss of lipopolysaccharide (LPS) expression. The activities of the host cationic antimicrobials LL-37 and human ...

Immunization with lipopolysaccharide-free outer membrane complexes protects against Acinetobacter baumannii infection
(Elsevier, 2018-07-05)
Outer membrane complex (OMC) vaccines, which contain antigens from the bacterial outer membrane, have been developed for multiple Gram-negative bacteria. However, OMC vaccines demonstrate high endotoxin activity due to the ...

Phenotypic changes associated with Colistin resistance due to Lipopolysaccharide loss in Acinetobacter baumannii
(Taylor & Francis, 2018)
Acinetobacter baumannii can acquire resistance to colistin via complete loss of lipopolysaccharide (LPS) biosynthesis due to mutations in the lpxA, lpxC and lpxD genes. However, although colistin is increasingly being used ...
