“…Or alternatively, we recommend introduction of serology for cysticercosis in screening of taeniasis carriers and STHs in order to detect asymptomatic NCC based on the recognition that cryptic infections are endemic and potentially most lethal parasitic disease on Bali (Margono et al, 2002;Sudewi et al, 2008;Wandra et al, 2015). When some people are confirmed antibody positive to diagnostic antigens for cysticercosis (Ito et al, 1998Sako et al, 2013;, they are recommended to admit big city hospital(s) for further treatment. However, there is a financial problem how to cover the admission fees!…”

“…Another pig (b) was full of fully developed cysticerci. These pigs were sero-positive to diagnostic antigens purified by cationexchange chromatography established by Sako et al (2013). It is very easy for people in endemic areas to recognize (b), but how to confirm such a small number of immature cysticerci (a) which may easily be evaluated to be free of cysticerci by a routine meat inspection (modified from Wandra et al, 2015).…”

IntroductionTaeniasis/cysticercosis, caused by the pork tapeworm, Taenia solium, is a parasitic zoonosis found primarily in countries where pigs are raised and meat inspection is lacking [1,2]. The potential for a tapeworm carrier to infect another individual (or themselves via autoinfection), resulting in cysticercosis or neurocysticercosis (NCC), is a risk not only in endemic areas, but also in areas with immigrants from endemic countries [1,[3][4][5]]. An example of such an outbreak occurred in an Orthodox Jewish community in New York City when family members were infected by a domestic employee from a T. solium endemic country [6]. Such NCC outbreaks have occurred in other developed countries, including countries in the Middle East where people do not consume pork [4,5,[7][8][9][10][11][12][13].In Asia, there are three Taenia tapeworms that infect humans; T. solium, Taenia saginata and Taenia asiatica [4,5,[14][15][16][17][18][19][20][21][22][23][24]. Although adult T. solium worms with scoleces are easily differentiated morphologically from other taeniids, it is almost impossible to differentiate adult T. asiatica and T. saginata [5,22,25,26]. Therefore, molecular differentiation is often required to correctly identify the infecting species [27]. Recent studies have also reported hybrids of T. saginata and T. asiatica in Thailand and China [5,25,[28][29][30][31][32]. This makes mitochondrial and nuclear gene analyses even more important for the differentiation of T. saginata, T. asiatica, and hybrids of these two species [30][31][32].In Indonesia, T. solium, T. saginata and T. asiatica are distributed according to livestock rearing and local food consumption practices [33][34][35][36][37][38][39][40]. Both T. saginata and T. solium have been confirmed from the island of Bali, where the local inhabitants are known to eat dishes that contain undercooked beef and pork, such as the traditional dish Lawar. NCC was considered endemic on Bali more than 20 years ago [41,42]. However, education programs aimed at keeping pigs indoors to prevent access to human faeces and the introduction of improved sanitation systems and practices have substantially reduced the prevalence of NCC during the past 2 decades [35,37,43]. Nevertheless, there are still sporadic NCC cases identified on Bali [40,[42][43][44][45]. Case ReportFieldwork conducted on Bali from 2002-2007 resulted in the identification of 69 taeniasis carriers who were treated with a single dose of praziquantel (PZQ) at 15 mg/kg body weight (Table 1). All worms were confirmed to be T. saginata by multiplex PCR [36]. In August 2007, a 47-year-old male taeniasis carrier from the Gianyar district suffered a single tonic-clonic seizure within a few hours of PZQ administration. The patient was subsequently admitted to the Sanglah Hospital in Denpasar. A computed tomography (CT) scan revealed one viable cystic lesion and one calcified lesion in the right frontal lobe of the brain. At this time, serology (ELISA) was also carried out using partially purified antigens by c...
