Indonesia: spatial distribution of Taenia solium and Cysticercosis in Bali. 27 février 2013

published on

Pork meat heavily infected by cysticerci (small white bladderlike spheroids), the larval stage of Taenia solium Human cysticercosis caused by the eggs of the pork tapeworm, Taenia solium, released by human tapeworm carriers, is one the major causative agent of the late onset epilepsy in developing countries where pork consumption is common. Control can be improved integrating human and animal epidemiology with host and parasite ecology.

In this programme supported by the Asahikawa Medical University and the Japanese Society for the Promotion of Science, we collaborate with Japanese (Pr. Akira Ito, Pr. Munehiro Okamoto, Dr. Yasuhito Sako, Dr Tetsuya Yanagida, etc.) and Indonesian (Dr Kadek Svastika, Dr Nyoman Sadra Dharmawan, Dr Tony Wandra, etc.) colleagues to provide research based evidence towards cysticercosis control, based on joining molecular, immunological and spatial ecology methods.
The areas studied in east Bali are in Gianyar and in Karangasem, for the latter at the foot of Mount Agung, an active strato-volcano whose last devastating eruption was in 1963-64. There, houses are scattered in discrete agriculture villages active mostly during the rainy season. During the dry season, workers emigrate to touristic areas of Bali to find jobs.
A field survey has been carried out in 2013, January 20-26, during the rainy season, in order to screen and localise Taenia solium/cysticercosis human carriers and cysticercosis pigs and to harmonize multi-disciplinary data collection and inter-operability in a context spatially explicit. This study will be pursued in early September.
