Objective - To develop a novel vaccine candidate through isolation of appropriate antigens and cloning these into the pseudomonas lipoprotein vector;- To verify the efficiency of these vaccines in mice and dog models, the latter to be developed in Algeria and Morocco.Expected Outcome- Improved knowledge of the genetic basis of antigens of L. infantum and L. major;- Several antigens isolated, cloned on pseudomonas and tested in different animal models with regard to their vaccination efficiency;- Novel approach to develop and test a vaccine that might be useful also for other vaccine preparations. Results - Production of L. major lipoprotein/GP63 fusion protein.- Cloning of L. infantum GP63 gene.- Use of GP63 fusion protein to detect antibodies in human infection by L. major and L. infantum.- Use of GP63 fusion protein to elicit antibodies in mice and detection of GP63 variants in old and new world Leishmania.- Establishment of canine models for L. infantum and L. major infection.- Characterisation of GP63 from field isolates and cloning and subcloning of regions of interest of GP63 (protein analysis, gene expression, gene structures);- Cloning of the GP63 genes into the Pseudomonas vector;- Acquisition of basic data on specific immunological responses of the human and canine populations at risk;- Testing of cloned GP63 with regard to their immunogenic activity in dog and mouse models followed by immunising dog-models with the most efficient clones;- Development of a candidate vaccine based on the identified immunising clones;- Testing of resistance of immunised animals against natural parasites less or more virulent (L. major / mouse model) or recent field isolates (L. infantum / dog model);- Development of a diagnosis technology based on antigens and to be carried out on blood samples.
