ABSTRACT:
The present invention presents novel leptospiral membrane lipoproteins, LipL1 and LipL2, associated with pathogenic strains of Leptospira. LipL1 is of about 35 kDa, and LipL2 is of about 41 kDa. Also disclosed are the method for purifying these proteins from Leptospira, their nucleotide and amino acid sequences, the cloning of the genes encoding the proteins and their recombinant proteins, methods for producing antibodies to these proteins, the resulting antibodies. These proteins, their immunogenim. fragments, and antibodies against them, are useful for inducing an immune response to pathogenic Leptospira as well as providing a diagnostic target for leptospirosis.
