Cloning, Expression and Characterization of Recombinant Exotoxin A-Flagellin Fusion Protein as a New Vaccine Candidate against Pseudomonas aeruginosa Infections
Background: Infections due to Pseudomonas aeruginosa are among the leading causes of morbidity and mortality in patients who suffer from impaired immune responses and chronic diseases such as cystic fibrosis. At present, aggressive antibiotic therapy is the only choice for management of P. aeruginosa infections, but emergence of highly resistant strains necessitated the development of novel alt...
متن کاملDevelopment of a Novel Anti-Adhesive Vaccine Against Pseudomonas aeruginosa Targeting the C-terminal Disulfide Loop of the Pilin Protein
The type IV pili (T4P) is a major virulence factor of Pseudomonas aeruginosa (P. aeruginosa) that is associated with primary adhesion, biofilm formation and twitching motility. This study focuses on the introduction of a novel biologically active subunit vaccine derived from the disulfide loop (DSL) of P. aeruginosa pilin. We investigated the expression of the novel PilA in-frame with pET26a ve...
متن کاملPurification and characterization of Pseudomonas aeruginosa exotoxin.
A trypsin-sensitive, heat-labile exotoxin of Pseudomonas aeruginosa strain P-A-103 has been purified by a procedure that includes membrane ultrafiltration, hydroxylapatite chromatography, ion-exchange cellulose chromatography, and gel filtration chromatography. The procedure resulted in the recovery of 48% of the exotoxin with a 40-fold increase in specific activity (micrograms of protein per m...

background: infections due to pseudomonas aeruginosa are among the leading causes of morbidity and mortality in patients who suffer from impaired immune responses and chronic diseases such as cystic fibrosis. at present, aggressive antibiotic therapy is the only choice for management of p. aeruginosa infections, but emergence of highly resistant strains necessitated the development of novel alt...
متن کاملInduction of Specific Humoral Immune Response in Mice against a Pseudomonas aeruginosa Chimeric PilQ/PilA Protein
Background: Pseudomonas aeruginosa, an opportunistic pathogen, is a common cause of healthcare-associated infections in immunocompromised individuals. The rapid emergence of multidrug-resistant strains has made P. aeruginosa infections progressively difficult to treat. In this study we evaluated the effect of a chimeric protein containing a P. aeruginosa PilQ fragment and the PilA disulfide loo...
