Abstract

Introduction: PSEUDOMONAS AERUGINOSA is a particular importance due to the numerous factors of pathogenicity and the prevalence of multi-resistance strains throughout the world. Therefore, the need to prevent and produce an effective vaccine seems necessary. The aim of this study was to use PLGA nanoparticles in the design of vaccine with ALGINATE antigens, lipopolysaccharide, and exotoxin, A PSEUDOMONAS AERUGINOSA. In this study, strain PAO1 of PSEUDOMONAS AERUGINOSA is used. Then, antigens including, ALGINATE, lipopolysaccharide, and EXOTOXIN A were extracted. Then, lipopolysaccharide was detoxified by hot phenol method. EXOTOXIN A was purified by chromatography and detoxified with formalin. Then, antigens separately conjugated to PLGA. FT-IR and AFM methods were usedto confirm conjugation with nanoparticles. A rabbit model was used to study the pyrogenic effects of conjugates. The mortality effect of conjugates on mouse model was tested.Materials and methods: The success of conjugation based on the size and charge of the nanoparticle was confirmed. The presence of antigenic functional groups in the structure of the nanoparticle and the formation of a steric bond confirmed with FT-IR results and the corresponding courier form.Results: The 3D conjugate images of nanoparticles before and after conjugation showed an increase in the height of nanoparticle binding sites. The change from initial sharpness to puff after the conjugation confirmed the success of conjugation. Failure to observe the pyrogenic effects in the rabbit and no mortality observed in mice was proved.Discussion and conclusion: All of the results showed that conjugates were effective in immunization. Therefore, it can be a candidate vaccine with a great potential against Pseudomonas causing diseases.
