Food-borne zoonotic cestode infections by Diphyllobothrium spp. and Spirometra spp. are relatively uncommon in Indonesia. So far, only one case of diphyllobothriasis was confirmed in 2004 in Jakarta, whereas there were 4 sparganosis cases in Indonesia. Morphology of eggs and gravid proglottids revealed the first case to be caused by Diphyllobothrium species. However, molecular identification of the species was not successful. Sparganosis may not be particularly rare in Indonesia, since Spirometra species have often been found in cats and other animals. These topics in Indonesia are briefly overviewed with reference to historical records and socio-cultural background information.

Three human taeniid species, Taenia solium, Taenia saginata and Taenia asiatica are distributed in Indonesia. A field survey conducted in Bali from 2002 to 2006 showed that the prevalence of taeniasis was highly variable among four districts (1.1-27.5%), and only two cysticercosis cases due to T. solium infection were detected. All tapeworms (n = 66) expelled from 66 tapeworm carriers were confirmed to be T. saginata by mitochondrial DNA analysis. A total prevalence of 13.0% (19⁄146) for T. solium taeniasis was found in Jayawijaya District, Papua (Irian Jaya). It included 14 of 88 (15.9%) in 1999 and 5 of 58 (8.6%) in 2001, while the seroprevalence of cysticercosis in humans by sub-district in Papua ranged from 0.0% in a non-endemic area to 48.5% in an endemic area from 1996 to 2005. The seroprevalence of cysticercosis in pigs and dogs in Jayawijaya ranged from 8.5% to 70.4% (1998-1999) and 4.9% to 33.3% (2000-2002), respectively. A 2003-2006 survey of 371 local people in Samosir island, north Sumatra revealed 6 of 240 (2.5%) to be infected with T. asiatica; 2 of 58 (3.4%) and 4 of 182 (2.2%) cases were detected in 2003 and 2005, respectively. This brief review summarizes the present situation of taeniasis and cysticercosis, the distribution of three human taeniid species, and the risk factors⁄transmission aspects of these tapeworm infections in Bali, Papua, and north Sumatra regions of Indonesia.
