Molecular cloning and expression of the cDNA sequence encoding a novel aspartic protease from Uncinaria stenocephala

- Anti-rUs-APR-1 antibodies confirm the production of the protease in U. stenocephala.
- The aspartic protease was detected in various life stages in A. ceylanicum.
- An effective vaccine would protect dogs against hookworms not limited to one species.
- The vaccine could be constructed from immunogenic epitopes from the key enzymes.
