The presence of two oncosphere antigens (OAs) of 22.5 and 31.3 kD in whole and excretory/secretory (ES) OA preparations of both Taenia solium and T. saginata or in antigen preparations from T. solium metacestodes or immature tapeworms was assessed. This included an evaluation of whether antibodies to other cestodes cross-reacted to these OAs. The OAs were present in whole oncosphere extract and...

Cestodes Since 1993 (1) several cases of sparganosis caused probably by Spirometra sp. have been observed. (5,6 and Samarasinghe S, personal communication). Bertiella studeri, an anoplocephalid tapeworm, is now recognised as a parasite acquired in areas where monkey reservoir hosts abound (7). As summarised by the present author (8) this cestode (Weerasooriya MV, Edirisinghe JS, personal commun...

Human neurocysticercosis, caused by the larval stage of the tapeworm Taenia solium, is an important neurological disorder reported as a major cause of epilepsy. An important risk factor for neurocysticercosis is the presence of human T. solium carriers who, upon open defecation, disseminate tapeworm eggs, which are infective to both humans and pigs. In the latter, infection also results in cyst...

A male patient with neurocysticercosis was identified in Montai Village, Xay District, Oudomxay Province, Lao PDR in February 2004. He had a history of diagnosis for neurocysticercosis by a CT scan in Thailand after an onset of epileptic seizure in 1993. A pig in the same district was found to contain Taenia solium metacestodes (=cysticerci); the slaughtered pig body contained more than 2,000 c...

INTRODUCTION In Nigeria, Taenia solium cysticercosis is a problem in rural areas where most pigs are kept and in urban areas where infected pork can be consumed. METHODOLOGY We performed enzyme linked immunosorbent assays on serum samples collected from pig rearers in Jos, Nigeria, to determine the prevalence of IgG antibodies. RESULTS Of 125 subjects tested, 12 (9.6%) were positive for T. ...

An epidemiological survey of taeniasis/cysticercosis was carried out in one semi-urban and two urban villages in three districts of Bali, Indonesia in 2002 and 2004. In total, 398 local people from 247 families were diagnosed by anamnesis and clinical examinations, and 60 residents were suspected to be taeniasis carriers. Among 60 suspected carriers, 56 persons expelled a total of 61 taeniid ad...

Abstract Background Cysticercosis is caused by parasitic infestation of larval stage pork tapeworm (Taenia solium). It a result accidental ingestion contaminated water and food from eggs tape worm due to poor sanitation. Pigs serve as intermediate host. The most common sites cysticercosis are the muscles, heart, liver but such tongue, buccal mucosa, cheek, or floor mouth rare. Case presentation...
