Design of Epitope Based Peptide Vaccine Against Pseudomonas Aeruginosa Fructose Bisphosphate Aldolase Protein using Immunoinformatics

Abstract

AbstractPseudomonas aeruginosais common pathogen that is responsible of serious illnesses hospital acquired infection as ventilator associated pneumonia and various sepsis syndrome. Also it is a multidrug resistant pathogen recognized for its ubiquity, its intrinsically advanced antibiotic resistant mechanisms. generally affects the immuonocompromised but can also infect the immunocompetent as in hot tub folliculitis. There is no vaccine against it available till now. This study predicts an effective epitope-based vaccine against Fructose bisphosphate aladolase (FBA) ofPseudomonas aeruginosausing immunoinformatics tools. The sequences were obtained from NCBI and prediction tests took place to analyze possible epitopes for B and T cells. Three B cell epitopes passed the antigenicity, accessibility and hydrophilicity tests. Six MHC I epitopes were the most promising, while four from MHC II. Nineteen epitopes were shared between MHC I and II. For the population coverage, the epitopes covered 95.62% of the alleles worldwide excluding certain MHC II alleles. We recommend invivo and invitro studies to prove it’s effectiveness.
