Cestodes are found endemic in certain areas of Indonesia. The most common cestodes found are Taenia saginata and Taenia solium. Eggs of Taenia are found in stool samples during surveys in Irian Jaya (2-9 %), Nusa Tenggara Timur (7 %), Bali and resettlement areas of people from Bali (0,4 - 3,3%). Interviews, with questions concerning expelled segments, recovered a prevalence of 9,5 % in inhabitants of the island of Samosir (North Sumatra) and 2 % in the people of 6 villages in Abiansemal (Bali). Cases are also reported from Jakarta. Hymenolepis nana (0,2 -1%) and Hymenolepis diminuta (0,4 %) are rarely found in surveys. A case of hyperinfection with H. nana has been reported in Jakarta in 1968. Occasionally there are reports of infections with Dipylidium caninum, Raillietina madagascariensis, Bertiella studeri and sparganum. Report on treatment of taeniasis in Indonesia mentioned the use of atabrine, mebendazole, bithionol and praziquantel with different results.
