Obtaining recombinant forms of the outer membrane protein F of Pseudomonas aeruginosa and assessment of their immunogenic properties

Obtaining recombinant forms of the outer membrane protein F of Pseudomonas aeruginosa and... Two recombinant forms of the outer membrane protein F (OprF) of Pseudomonas aeruginosa were obtained, the full-length protein OprF and the C-terminal part of the OprF protein (aa 192–342). As a result of double immunizations, these recombinant proteins provided mice with resistance to experimental intraperitoneal challenge with P. aeruginosa. The best protective effects were observed at a dose of 25 μg for OprF and 50 μg for the truncated OprF variant (indices of efficiency were 3.3 and 2.8, respectively). Rabbit antisera immune to the recombinant proteins were also able to protect mice from the experimental infection with P. aeruginosa. Indices of efficiency were 6.4 for OprF and 6.0 for the OprF C-terminal part; these values were approximately two times as high as the effect of sera from intact test animals (3.2). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

Two recombinant forms of the outer membrane protein F (OprF) of Pseudomonas aeruginosa were obtained, the full-length protein OprF and the C-terminal part of the OprF protein (aa 192–342). As a result of double immunizations, these recombinant proteins provided mice with resistance to experimental intraperitoneal challenge with P. aeruginosa. The best protective effects were observed at a dose of 25 μg for OprF and 50 μg for the truncated OprF variant (indices of efficiency were 3.3 and 2.8, respectively). Rabbit antisera immune to the recombinant proteins were also able to protect mice from the experimental infection with P. aeruginosa. Indices of efficiency were 6.4 for OprF and 6.0 for the OprF C-terminal part; these values were approximately two times as high as the effect of sera from intact test animals (3.2).
