Dear Editor:
The letter of Galan-Puchade and Fuentes clearly describes the importance of T. asiatica in the epidemiology of porcine and human cysticercosis. We agree that it is important to develop an immunologic test to distinguish T. solium from T. asiatica cysticercosis. We plan to test the T. solium cathepsin L-like protein fraction for cross reactions with T. asiatica cysticercosis.
