The objective of this study was to observe the development, distribution, and infection density ofTaenia saginata metacestodes in Bali cattle. Three Bali cattle were experimentally infected with T. saginataeggs which were collected from taeniasis patients. The experimental animal was inoculated with : i)1000,00 T. saginata; ii) 500,000 eggs; and iii) 1,000,000 eggs, respectivelly 100,000 (cattle 1), 500,000(cattle 2), and 1,000,000 (cattle 3) T. saginata eggs, respectively. To observe the development of cysticerci,all cattle were slaughtered at 24 weeks post infection. To observe their distribution and density, slicingwas done to the cattle?s tissues. The study results showed that cysts were found distributed to all muscletissues and some visceral organs such as heart, diaphragm, lungs, and kidney of the cattle infected with100,000 and 500,000 T. saginata eggs. Density of the cyst was in the range of 11 to 95 cysts per 100 gramsof tissue. The highest density was noted in the heart (58/100 grams) and in diaphragm (55/100 grams).This study has confirmed that T. saginata eggs derived from taeniasis patient in Bali, if infected to Balicattle can develop and spread to all muscle tissues and some visceral organs. From this study it wasconcluded that it is necessary to include the heart in the meat inspection at slaughter house for possibilityof T. saginata cyst infection.$?

Penelitian ini dikerjakan di Br Pamesan, Desa Ketewel, Gianyar (penduduk: 765 orang). Tujuan penelitian adalah untuk mengetahui angka prevalensi taeniosis dan sistiserkosis di banjar tersebut. Untuk menentukan prevalensi taeniosis dipergunakan teknik mikroskopi hapusan langsung dan koproantigen ELISA. Untuk menetapkan prevalensi sistiserkosis dipakai teknik imunoblot /Western blot. Selain itu juga dikerjakan wawancara memakai kuesioner terhadap subjek penelitian dan kepala rumah tangga, untuk mendapat data yang terkait dengan epidemiologi. Dari 156 feses yang diperiksa, ternyata 2 mengandung Taenia, jadi prevalensi taeniosis adalah 1,3%. Kedua kasus ternyata disebabkan oleh T. saginata. Dari 115 serum yang diperiksa, 6 menunjukkan hasil seropositip, berarti prevalensi sistiserkosis adalah 5,2%. Kasus tersebut terdiri dari 3 laki dan 3 perempuan, berumur antara 26-46 tahun. Di samping kelompok penelitian, 13 orang yang mengeluh mengeluarkan proglotida juga diperiksa, dan ternyata 8 diantaranya mengandung infeksi Taenia, terdiri dari 7 T. saginata dan 1 T. solium. Dua diantaranya menunjukkan hasil seropositip dengan pemeriksaan imunoblot, seorang terinfeksi T.solium dan yang lainnya T.saginata. Hasil penelitian ini lebih menegapkan lagi bahwa taeniosis dan sistiserkosis memang endemis pada penduduk Pulau Bali. Kata kunci: taeniosis/.sistiserkosis; mikroskopi; koproantigen; imunoblot; Bali ABSTRACTThis study was carried out in Banjar Pamesan, in the Village of Ketewel, District of Gianyar (population: 765). The study objective was to assess the prevalence of taeniosis and cysticercosis in the hamlets population. For determination of taeniosis prevalence the techniques used were direct smear microscopy and coproantigen ELISA. To determine the prevalence of cysticercosis, immunoblot/Western blot technique, using crude extract of T. soliuna cysticercus, was used. Interviews were also done to the study subjects and their respective heads of households to obtain a variety of data related to the epidemiology of taeniosis/ cysticercosis. Of 156 fecal samples examined. 2 were positive for Taenia, giving a prevalence of taeniosis of 1,3%. Both cases were caused by T. saginata. Of 115 sera examined, 6 showed presence of anti T. solium cysticercus antibody (prevalence of cysticercosis: 5,2%). The six cases consisted of 3 males and 3 females, aged between 26 and 46 years. Additional 13 persons reporting of having expelled proglottids were examined, and 8 were found to have taeniosis, 7 with T. saginata and I with T. soliuun. Two of them were found seropositive by immunoblot; who were infected with T.saginata and T solium respectively. This study has reconfirmed the endemicity of taeniosis and cysticercosis in the population of Bali. Key words: taeniosis/cysticercosis; microscopy; coproantigen; immunoblot; Bali

Cysticercosis zoonotic parasitic disesase caused by Taenia solium larva, is a major public healthproblem. Cysticercosis results from the development of larval tapeworms in humans harboring adult T.solium or from ingesting soil containing eggs shed in the feces of humans, in areas where there are nolatrines. Humans are accidental intermediate hosts and pigs are the normal intermediate hosts. Clinicallythey are most serious when located in the central nervous system or in the eye where they persist formonths to years. Cysticercosis occurs worldwide primarily in developing country where pigs are raised,pork consumed and poor sanitation allows pigs’ access to human faeces. The occurance of the diseases isexpected to increase in relation to the growing demand for pork in those countries. In Indonesia cyticercosisis still a very important health problem, especially in Bali and Papua. The majority of the populations inBali and Papua are Hindus and Protestants/Catholics, respectively, so pork widely consumed in thoseislands. This brief review summarizes the present situation and problems of cysticercosis in animal inBali and Papua. Epidemiological data of the diseases were obtained from several sources.

A cross-sectional study was carried out from March until September 1992 in 4 different geo-climatic rural villages in Bali to assess the prevalence of Strongyloides stercoralis infection related to age, gender and geo-climatic condition. The number of selected samples using multistage stratified random sampling based on age and gender was 2880. Strongyloides larvae in stool samples were identified by modified Harada Mori fecal culture technique. The results showed that the overall prevalence of Strongyloides infection was 1.6%; the prevalence in male was 1.2% and in female was 2.1%, however the gender difference was not statistically significant. In term of age, there was no statistically significant difference. The highest prevalence (2.4%) was found among 7-12 years children, followed by aged 7 years or less (1.6%), 18 years or over (1.6%), and 13-18 years (0.6%). The prevalence of Strongyloides infection related to geo-climatic conditions was significantly difference. The highest prevalence of Strongyloides infection was at wet highland (3.3%), followed by wet lowland (1.5%), dry highland (1.0%), and dry lowland (0.9%). In conclusion, the prevalence of Strongyloides stercoralis infection in Bali was very low. Prevalence of Strongyloides infection was highly related to geo-climatic type of area, but not to gender and age groups.
