| host-parasite interactions in taenia solium cysticercosis. | human neurocysticercosis results from infestation of the central nervous system with the metacestode form (tissue cyst) of taenia solium. cysticercosis is being increasingly recognized as a cause of neurologic symptoms in residents and emigrants from developing countries. taeniid parasites have developed elaborate mechanisms to persist in the tissues of their intermediate hosts. the invasive larvae, termed oncospheres, are susceptible to antibody and complement. however, by the time that the hos ... | 1992 | 1365544 |

| neurocysticercosis: neurologic, pathogenic, diagnostic and therapeutic aspects. | worldwide neurocysticercosis is the most common parasitic infection of the human brain and meninges. clinical features of the illness vary with the stage of ova infection, but most problems arise when the mature cyst degenerates. seizures, increased intracranial pressure, and focal neurologic signs then often develop. computed tomography and magnetic resonance usually demonstrate cysticercus cellulosae cysts in the brain. a new immunoblot test for antibodies to the cysticercus seems both sensiti ... | 1991 | 1868865 |
