Analysis of transcription of the exotoxin A gene of Pseudomonas aeruginosa.
Analysis of RNA isolated from Pseudomonas aeruginosa PA103 and PAKS grown under Fe2+-limiting (0.08 microgram/ml) and Fe2+-sufficient (10 micrograms/ml) conditions demonstrated that exotoxin A (ETA) expression is regulated by Fe2+ at the level of transcription. S1 nuclease mapping revealed two 5' termini of the tox transcript, 89 base pairs (bp) (S1A) and 62 bp (S1B) 5' to the ETA initiation co...
متن کاملCloning, 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...

PREPARATION AND EVALUATION OF PROPERTIES OF PSEUDOMONAS AERUGINOSA EXOTOXIN A CONJUGATE WITH GOLD NANOPARTICLES
Background & Aims: Pseudomonas aeruginosa is an opportunistic pathogen and most important cause of hospital infections, which causes septicemia and death through various virulence factors such as exotoxin A. In the present study, P. aeruginosa exotoxin A (as a toxic factor) was prepared with the aim of obtaining a new recombinant vaccine candidate and conjugated with gold nanoparticles and its ...
متن کاملCloning of a gene involved in regulation of exotoxin A expression in Pseudomonas aeruginosa.
We have cloned a gene from Pseudomonas aeruginosa that stimulates the expression of exotoxin A. A recombinant library of genomic DNA from strain PA103 constructed with a broad-host-range plasmid vector containing chromosomal insert fragments generated by Sau3A was used to transform the hypotoxigenic mutant strain PA103-29. A recombinant plasmid, pFHK6, was isolated from a PA103-29 transformant ...
