Abstract

Aim. Evaluation of immunobiological prop- erties of recombinant atoxic forms of the Pseudomonas aeruginosa exotoxin. Materials and methods. 3 recombinant atoxic forms of the P.aeruginosa exotoxin A were produced and studied: aTox1, consisting only of exotoxin A domain 1; aTox1,2, consisting of domain 1 and 2 ; and aTox1,2, Δ 3 , consisting of both domain 1 an d 2, and part of domain 3. Results. aTox1,2 and a T ox1,2, Δ 3 had distinctive antigenic properties. F ormulation s based on these recombinant pro- teins were immunogenic and protected animals from exotoxin A in experimental conditions. Conclusion. These results may be used to construct direct-action immunobiological formulations.
