ABSTRACT:
Chimeric gene formed by the DNA sequences that encode the antigenic determinants of four proteins ofL. infantum, useful for the serological diagnosis of canineLeishmaniosisand protein obtained, that consists of the prior employment of a cloning strategy. A clone is obtained which expresses the protein rLiPO-Ct-Q (pPQI). To this initial vector, by means of the use of suitable restriction targets, DNA fragments are sequentially added that are encoded in other proteins and after each cloning step the correct orientation of each one of the inserts reduces the size of the expression products, the complete nucleotide sequence of the final pPQV clone being determined. A chimeric polypeptide encoded by the chimeric gene is obtained with a molecular mass of 38 kD and with an isoelectric point of 7.37. This chimeric polypeptide is useful for preventing and/or treatingLeishmaniosisin animals or humans.
