Abstract

Leptospirosis is a neglected bacterial disease affecting humans and various mammals with a high mortality rate. Vaccination is the most effective prevention strategy but most current vaccines do not protect against new serovars emerged in the past few years. COVALEPT will isolate and characterize virulent circulating strains from the field. Protective antigens conserved amongst Leptospira will be identified by bioinformatics, produced in native or recombinant form and assessed in vivo in order to conceive a broad spectrum vaccine for multi-species applications.       


Objectives

Providing: - A leptospirosis vaccine candidate for dogs and potentially other species - Bioinformatics, molecular and biochemical tools that could accelerate the discovery and development of other bacterial antigen targets
