  • Antigens for diagnosing neurocysticercosis
    Patent number: 4855408
    Abstract: Two substantially purified larval T. solium antigens found circulating in the cerebrospinal fluid of patients infected with T. solium, having molecular weights of 190 KD and 230 KD, are disclosed. These antigens, alone or in combination, may be used to diagnose or to follow the course of neurocysticercosis, caused by T. solium infection.
    Type: Grant
    Filed: May 27, 1988
    Date of Patent: August 8, 1989

  • Immunological methods for diagnosing neurocysticercosis
    Patent number: 4801532
    Abstract: Immunological methods are disclosed for diagnosing active human neurocysticercosis, including a serum test and a cerebrospinal fluid test. The serum test involves detecting an antibody in serum which recognizes at least one of three particular antigens isolated from Taenia solium larvae. The cerebrospinal fluid test involves detecting an antigen or antigens of larval origin, preferably by an ELISA technique.
