The Leptospira spp. immunoprotective peptides disclosed herein elicit protective immunity against subsequent challenge or exposure to at least two Leptospira spp. serovars. This is the result of a 4-year ongoing collaborative work within the COVALEPT Consortium.
ABOUT COVALEPT
COVALEPT gathers a consortium of the following partners: Merial (coordinator), Calixar, Genostar, Vetagro-Sup, PX Therapeutics and Institut Pasteur.
The project aims at providing a leptospirosis vaccine candidate with canine and potentially multi-species application, using bioinformatics, molecular and biochemical tools allowing to accelerate the discovery and development of this specific target as well as other bacterial antigen targets (More information).
