Study of the immunogenicity of outer membrane protein A (ompA) gene from Acinetobacter baumannii as DNA vaccine candidate in vivo
Objective(s): Acinetobacter baumannii is one the most dangerous opportunistic pathogens in hospitalized infections. This bacterium is resistant to 90% of commercial antibiotics. Therefore, developing new strategies to cure A. baumannii-infections is urgent. The DNA vaccines new approach in which the immunogen can be directly expressed inside the target cells through cl...
متن کاملSilver Resistance In Acinetobacter baumannii BL54 Occurs Through Binding to a Ag-Binding Protein
The mechanism of plasmid mediated silver (Ag) resistance was investigated in Acinetobacter baumanniiBL54. The intracellular accumulation of Ag in both original strain BL54 and Escherichia coli K12transconjugant containing plasmid pUPI276 began immediately and reached a maximum within 60 minutes.This initial accumulation was followed by net loss of Ag which reached a maximum wi...
متن کاملLoss of a 29-kilodalton outer membrane protein in Acinetobacter baumannii is associated with imipenem resistance.
We analyzed the possible causes of imipenem (IPM) resistance in multidrug-resistant isolates of Acinetobacter baumannii. Comparison of the outer membrane protein (OMP) profiles of two genomically related strains (Ab288 [IPM sensitive] and Ab242 [IPM resistant]) indicated the conspicuous loss of a 29-kDa polypeptide in the Ab242 strain. No carbapenemase activity was detected in any of these stra...
متن کاملChannel formation by CarO, the carbapenem resistance-associated outer membrane protein of Acinetobacter baumannii.
It has been recently shown that resistance to both imipenem and meropenem in multidrug-resistant clinical strains of Acinetobacter baumannii is associated with the loss of a heat-modifiable 25/29-kDa outer membrane protein, called CarO. This study aimed to investigate the channel-forming properties of CarO. Mass spectrometry analyses of this protein band detected another 25-kDa protein (called ...
متن کاملAcinetobacter baumannii Secretes Cytotoxic Outer Membrane Protein A via Outer Membrane Vesicles
Acinetobacter baumannii is an important nosocomial pathogen that causes a high morbidity and mortality rate in infected patients, but pathogenic mechanisms of this microorganism regarding the secretion and delivery of virulence factors to host cells have not been characterized. Gram-negative bacteria naturally secrete outer membrane vesicles (OMVs) that play a role in the delivery of virulence ...
