High prevalence of Taenia saginata taeniasis and status of Taenia solium cysticercosis in Bali, Indonesia, 2002-2004.

An epidemiological survey of taeniasis/cysticercosis was carried out in one semi-urban and two urban villages in three districts of Bali, Indonesia in 2002 and 2004. In total, 398 local people from 247 families were diagnosed by anamnesis and clinical examinations, and 60 residents were suspected to be taeniasis carriers. Among 60 suspected carriers, 56 persons expelled a total of 61 taeniid adult worms after praziquantel treatment. From 398 residents, 252 stool samples were available for analysis of taeniid eggs, coproantigens or copro-DNA for identification of taeniid species, and 311 serum samples were available for detection of antibodies against Taenia solium cysticercosis. Taeniasis prevalences were highly variable among three villages (1.1-27.5%), and only one case of cysticercosis due to T. solium infection was detected. All expelled tapeworms were confirmed to be Taenia saginata by mtDNA analysis. There was no Taenia asiatica human case in Bali. Case control analysis of 106 families chosen at random from 179 families in 2004 and another 106 families from non-endemic areas revealed that risk factors of T. saginata taeniasis for families were: level of education (P<0.01); consumption of beef lawar (P<0.01); and the source of lawar (P<0.01).

Neighbourhood-based waste management: a solution for solid waste problems in Jakarta, Indonesia.

Municipal solid waste management in the capital city of Indonesia, Jakarta, is examined from a point of view of researchers and waste management practitioners. Major impediments to waste management in Jakarta include non-involvement of stakeholders in planning and decision-making, unskilled staff undertaking the duty, the absence of long-term waste management strategies, and weak coordination between authorities and neighbourhood association workers who undertake primary collection. It was revealed that lack of resources is seen as the least important of all impediments. The success of managing solid waste in Jakarta cannot be separated from the presence and the role of a neighbourhood association, which performs waste collection on a daily basis as well as keeping their respective areas clean by employing their own waste service workers. A neighbourhood-based waste management strategy is a promising solution for Jakarta, because it is more applicable and suitable for Jakarta's context compared to community-based waste management. The performance of this approach is examined and the improvement for wider adoption is discussed for a long-term solution.

Hospital based clinical surveillance for dengue haemorrhagic fever in Bandung, Indonesia 1994-1995.

In Indonesia, by law dengue haemorrhagic fever (DHF) cases must be reported within 24 h to the district health authority. The objective of this study was to evaluate the adequacy, accuracy and reporting delay of this reporting system. In four major hospitals of the city of Bandung, medical records of hospitalised DHF cases admitted between April 1994 and March 1995 were reviewed. This list of DHF cases was compared with the list of reported cases to the Bandung Municipality Health Office. During the study period, 569 DHF cases and 81 dengue shock syndrome (DSS) cases were diagnosed. Only 199 (31%) of the 650 hospitalised cases with suspected DHF/DSS were reported to the Bandung Municipality Health Office. The percentage of fatal cases was significantly lower among all hospitalised cases 11/650 (1.7%) than among reported cases 5/199 (2.5%). In only 443 of the 583 hospitalised cases (76%) in which a dengue serological test was performed, was this test positive. Of the 199 reported DHF/DSS cases 151 (76%) had a positive haemagglutination inhibition test. This study shows that the surveillance system for DHF/DSS in Bandung should be strengthened. DHF/DSS cases should be reported on the basis of a diagnosis made during hospitalisation preferably after a serological confirmation is obtained.

Douching and sexually transmitted diseases in pregnant women in Surabaya, Indonesia.

OBJECTIVE: Our purpose was to investigate the association between douching (douching agents and timing) and sexually transmitted disease. STUDY DESIGN: A cross-sectional survey of sexually transmitted diseases and habits of vaginal douching was performed on 599 pregnant women who visited a prenatal clinic in Surabaya, Indonesia. RESULTS: Of the 599 pregnant women, 115 (19.2%) had at least one sexually transmitted disease (gonorrhea, chlamydia, syphilis, trichomoniasis, or herpes simplex virus-2). Most women had douched with water (19%) or water and soap (63%) at least once in the preceding month. Approximately 10% of the women had douched in the preceding month with a commercial agent (2%) or betel leaf (8%). Douching with water alone after sex was not associated with sexually transmitted disease. Douching with water and soap or with a betel leaf or commercial agent after sex was associated with sexually transmitted disease; adjusted odds ratios were 2.6 (95% confidence interval 1.0 to 7.1) and 2.7 (95% confidence interval 0.5 to 14.5), respectively. The association was enhanced if the women douched before sex or both before and after sex; adjusted odds ratio were 2.7 (95% confidence interval 1.0 to 7.3) for douching with water and soap and 5.2 (95% confidence interval 1.6 to 16.7) for douching with betel leaf or a commercial agent. Compared with women who never douched, women who always douched with betel leaf or a commercial agent had a substantially increased risk for sexually transmitted disease (adjusted odds ratio 9.4, 95% confidence interval 1.8 to 50.3). CONCLUSIONS: We found a significant association between sexually transmitted disease and douching habits (douching with betel leaf, commercial agents, or water and soap). However, further prospective investigations are needed to evaluate the temporal relationship between douching and sexually transmitted disease.

Resurgence of cases of epileptic seizures and burns associated with cysticercosis in Assologaima, Jayawijaya, Irian Jaya, Indonesia, 1991-95.

Historically, neurocysticercosis (NCC) caused by the larval stage, cysticercus or cysticerci, of the pork tapeworm Taenia solium was recognized in Paniai District, western Irian Jaya Province, Indonesia, in the early 1970s. In the 1990s, we observed a rapid increase in the number of cases of epileptic seizures and burns in Assologaima Sub-District, Jayawijaya District, eastern Irian Jaya. There were totals of 1120 new cases of burns and 293 new cases of epileptic seizures during 1991-95 in Assologaima where the number of inhabitants was 15,939. Histopathological examination of resected cysts from patients and a pig revealed that they were cysticerci of T. solium. DNA analysis of these cysts revealed that the nucleotide sequences of 391 base-pair fragments of the mitochondrial cytochrome c oxidase subunit 1 gene were exactly the same in those from patients and the pig. Although 3 of 391 base-pair fragments might differ from that of T. solium reported previously, there were no differences in the amino-acid sequences. Approximately 67% and 65% of persons with epileptic seizures and with subcutaneous nodules, respectively, showed antibody responses highly specific to cysticercosis. Therefore, most cases of epileptic seizures and burns were considered to be associated with cysticercosis in Irian Jaya.

Epidemic dengue transmission in southern Sumatra, Indonesia.

An outbreak of dengue fever (DF), dengue haemorrhagic fever (DHF), and dengue shock syndrome (DSS) in the city of Palembang, south Sumatra, Indonesia was investigated to (i) validate epidemic occurrence, (ii) confirm dengue virus aetiology and associated serotype(s), (iii) provide a demonstrable measure of community impact, and (iv) identify causative relationship (if any) with climatic El Niño Southern Oscillation (ENSO) influences. Trend analysis based on a 6-year retrospective review of hospital records demonstrates a 3-fold increase in clinical cases for the outbreak period (January-April 1998), relative to historical records. In the 2 hospitals surveyed, the monthly mean number of outbreak-related dengue cases over 4 months was 833 (range 650-995 cases/month); the mean monthly value for the previous 72 months was 107 (range 14-779 cases/month). An apparent trend in epidemic transmission was observed, evolving from a 5-year cyclic phenomenon to an annual occurrence, often indistinguishable from one year to the next. The proportional distribution of clinical outbreak cases into DF, DHF and DSS diagnostic categories was 24%, 66%, and 10%, respectively. The population aged 10-19 years accounted for the largest (35%) proportion of hospitalized DHF cases, followed by children aged 5-9 years (25%) and children aged 4 years (16%). Serum samples obtained during acute illness from 221 hospitalized patients were examined using serology, RT-PCR, and virus isolation in cell culture: 59% of samples had laboratory evidence of a dengue infection. All 4 dengue virus serotypes (DEN 1-4) were identified in epidemic circulation, with DEN 3 predominating (43%). DEN 1 was the principal serotype associated with less severe dengue illness, suggesting that virulence may be, in part, a function of infecting serotype. The climatic influence of ENSO on rainfall and temperature in the months leading up to and during the outbreak was dramatic, and is likely to contribute to favourable outbreak conditions.

Mutations in the pfmdr1, dhfr and dhps genes of Plasmodium falciparum are associated with in-vivo drug resistance in West Papua, Indonesia.

This study (conducted in 1996-99) examines the association of mutations in pfmdr1, dihydrofolate reductase (dhfr) and dihydropteroate synthase (dhps) genes of Plasmodium falciparum with in-vivo drug resistance in West Papua, Indonesia. Initially, 85 patients infected with P. falciparum were treated with chloroquine, of whom 21 were cleared of parasites, 49 had parasitaemias classified as RI, RII or RIII resistance and 1 patient had recrudescent parasitaemia. Fansidar (pyrimethamine-sulfadoxine) was the second-line treatment and 18 patients were cleared of parasites and 31 had continuing infections classified as RI, RII or RIII resistance and 1 patient had recrudescent parasitaemia. The pfmdr1, dhfr and dhps genes were examined for mutations previously shown to be associated with resistance to these drugs. In this study, mutations in pfmdr1 were associated with chloroquine resistance and mutations in both dhfr and dhps were associated with Fansidar resistance in vivo. Interestingly, Gly-437 in dhps along with Arg-59/Asn-108 in dhfr were associated with RI, RII and RIII resistance whereas Glu-540 was highly associated with only RII and RIII Fansidar resistance. This finding supports the hypothesis that the molecular basis of RI, RII and RIII Fansidar resistance involves an accumulation of mutations in both dhfr and dhps. These results suggest that mutations in both dhfr and dhps genes are a good predictor of potential Fansidar treatment failure.

Nutrient budget for Saguling Reservoir, West Java, Indonesia.

A preliminary nutrient budget for Saguling Reservoir is reported as a first attempt to quantify the behaviour of nutrients entering this reservoir. This work is part of a larger Indonesia-Australia collaborative research and training project, involving Padjadjaran University and Monash University, established to study nutrient dynamics in Saguling Reservoir. Saguling Reservoir, the first of a chain of three large reservoirs (Saguling, Cirata and Jatilahur), built on the Citarum River in central Java, was completed in 1985. It has already become highly polluted, particularly with domestic and industrial effluent (organic matter, nutrients, heavy metals) from the urban areas of Bandung (population 2 million). The reservoir experiences major water quality problems, including excessive growths of floating plants, toxic cyanobacterial blooms and regular fish-kills. The work reported in this paper shows that Saguling receives a very large nutrient load from the city of Bandung and because of this, is highly eutrophic. It is unlikely that the water quality of Saguling will improve until a substantial part of Bandung is sewered and adequate discharge controls are placed on the many industries in the region upstream of the reservoir.

Blood lead levels and risk factors for lead poisoning among children in Jakarta, Indonesia.

The phase-out of leaded gasoline began in Jakarta, Indonesia on July 1, 2001. We evaluated mean blood lead levels (BLLs) and the prevalence of elevated BLLs of Jakarta school children and assessed risk factors for lead exposure in these children before the beginning of the phase-out activities. The study involved a population-based, cross-sectional blood lead survey that included capillary blood lead sampling and a brief questionnaire on risk factors for lead poisoning. A cluster survey design was used. Forty clusters, defined as primary schools in Jakarta, and 15 2nd- and 3rd-grade children in each cluster were randomly selected for participation in the study. The average age of children in this study was 8.6 years (range 6-12) and the geometric mean BLL of the children was 8.6 microg/dl (median: 8.6 microg/dl; range: 2.6-24.1 microg/dl) (n=397). Thirty-five percent of children had BLLs > or =10 microg/dl and 2.4% had BLLs > or =20 microg/dl. Approximately one-fourth of children had BLLs 10-14.9 microg/dl. In multivariate models, level of education of the child's primary caregiver, water collection method, home varnishing and occupational recycling of metals, other than lead, by a family member were predictors of log BLLs after adjustment for age and sex. BLLs of children who lived near a highway or major intersection were significantly higher than those of children who lived near a street with little or no traffic when level of education was not included in the model. Water collection method was a significant predictor of BLLs > or =10 microg/dl after adjustment for age and sex. BLLs in children in this study were moderately high and consistent with BLLs of children in other countries where leaded gasoline is used. With the phase-out of leaded gasoline, BLLs of children in Jakarta are expected to rapidly decline as they have in other countries that have phased lead out of gasoline.

Emissions and environmental implications of mercury from artisanal gold mining in North Sulawesi, Indonesia.

In artisanal gold mining practiced in North Sulawesi Island, Indonesia, gold is separated from ore by the use of mercury, which forms an amalgam with gold. All related processes are undertaken with a low level of technical knowledge and skills, no regulation, and with disregard for the safety of human and environment health. The situation is generating serious potential health and environmental risks in the area. As part of an ongoing monitoring program, total mercury concentrations were examined in water, bottom sediment and fish samples from three main rivers in Talawaan Watershed, which receives drainage from gold mining practices. Monitoring began in May-June 2000, almost 2 years after artisanal gold mining had begun. At that time, the mercury concentration in the sediment was generally low, except in places close to the gold processing plants. In the present study, a more systematic sampling and analysis was conducted in May-June 2001. Bottom surface sediments, water, and fish samples were collected at 12 sites along the three main rivers in the watershed. In addition, one site outside the watershed was sampled to serve as a control. Sample collections were conducted in three phases in duplicate, with two-week intervals between each phase. The mercury concentration observed in this study indicated that an increase took place along the three main rivers in the watershed. Solutions to this problem must be formulated as soon as possible in order to avoid a major health, economic, and ecological disaster arising from the continuing discharge of Hg. The present study proposes that mercury dispersion occur downstream of the mining.

Chloroquine-resistant Plasmodium malariae in south Sumatra, Indonesia.

Oral chloroquine is the treatment of choice for uncomplicated Plasmodium malariae infections worldwide. We did a prospective 28-day in-vivo assessment of the efficacy of chloroquine for treatment of P malariae on Legundi Island in Lampung Bay, Sumatra, Indonesia. Of 28 patients, one had recurrent parasitaemia on day 28, and two had persistent parasitaemia to day 8. Whole-blood chloroquine and desethylchloroquine concentrations were at ordinarily effective levels (> or = 100 microg/L) on day 8 in both cases of persistent parasitaemia. These findings suggest that clinical resistance to chloroquine by P malariae occurs in the Indonesian archipelago of southeast Asia.

RII and RIII type resistance of Plasmodium falciparum to combination of mefloquine and sulfadoxine/pyrimethamine in Indonesia.

2 of 36 Plasmodium falciparum infections were resistant (RII and RIII) in vivo to the combination of mefloquine (M) and sulfadoxine-pyrimethamine (SP) in Jayapura, Irian Jaya, Indonesia. Expected absorption of mefloquine and pyrimethamine was confirmed in the one resistant patient from whom sera were available, and the isolate from this patient was sensitive to mefloquine in vitro. Only 2 of 41 infections studied at the same time were resistant in vivo to SP. There was no clinical advantage of MSP compared with SP, and limited observations suggest there may be a disadvantage.

The microbial ecology of cocoa bean fermentations in Indonesia.

Cocoa beans are the principal raw material of chocolate manufacture. The beans are subject to a microbial fermentation as the first stage in chocolate production. The microbial ecology of bean fermentation (Forastero and Trinitario cultivars) was investigated at three commercial fermentaries in East Java, Indonesia by determining the populations of individual species at 12-h intervals throughout the process. The first 2-3 days of fermentation were characterised by the successional growth of various species of filamentous fungi, yeasts, lactic acid bacteria and acetic acid bacteria. The principal species found were Penicillium citrinum, an unidentified basidiomycete, Kloeckera apis, Saccharomyces cerevisiae, Candida tropicalis, Lactobacillus cellobiosus, Lactobacillus plantarum and Acetobacter pasteurianus. The later stages of fermentation were dominated by the presence of Bacillus species, mostly, Bacillus pumilus and Bacillus licheniformis. Glucose, fructose, sucrose and citric acid of the bean pulp were utilised during fermentation, with the production of ethanol, acetic acid and lactic acid that diffused into the beans. The filamentous fungi were notable for their production of polygalacturonase activity and probably contributed to the degradation of bean pulp.

Efficacy trial of single-dose live oral cholera vaccine CVD 103-HgR in North Jakarta, Indonesia, a cholera-endemic area.

A randomized, double-blind, placebo-controlled efficacy trial of one dose of CVD 103-HgR live oral cholera vaccine was performed in Indonesia from 1993 to 1997. 67,508 persons aged 2-41 years ingested vaccine or placebo and were followed for four years, detecting cholera cases using hospital-based surveillance. A nested reactogenicity study (538 vaccinees, 535 controls) revealed no vaccine-attributable side effects. A nested immunogenicity study (N=657) showed vibriocidal seroresponses in 64-70% of vaccinees vs 1-2% of controls. Cholera incidence was lower than expected. 103 cases of Vibrio cholerae O1 El Tor diarrhea were detected, 93 evaluable for vaccine efficacy (43 vaccine, 50 placebo; efficacy=14%). A suggestion of protection was observed among persons with blood group O [P=0.12]. Only seven cases occurred within six months of vaccination, precluding assessment of short-term efficacy. In Jakarta, single-dose CVD 103-HgR did not confer long-term protection. Short-term protection from a single-dose and long-term protection from two doses have yet to be studied.

Influence of illegal gold mining on mercury levels in fish of north Sulawesi's Minahasa Peninsula, (Indonesia).

North Sulawesi's Minahasa Peninsula currently is experiencing intense illegal gold mining activity. It has been estimated that 200 t of mercury are used annually in Indonesia in the recovery of gold from the illegal mines. To date no study has assessed the environmental impact of this illegal activity on the nearby aquatic biota. To address this concern, we compared tissue mercury levels from several sites, including a reference site and a site near an illegal mine. Fish from the region of the illegal mine contained 30 times the mercury content of fish at the reference site. Moreover, whole fish tissue levels were four times those recommended by the World Health Organization for consumption restrictions and often two-fold higher than recommended for total restriction on fish consumption. The environmental and human health implications of these levels are of grave concern; citizen education programmes are required to alert indigenous peoples of the risks associated with mercury exposure and fish consumption guidelines put into place. A more comprehensive effort to identify major sources and effects are required. Such information can be used to determine the correct course of action that needs to be taken to close existing illegal mines and prevent future illegal mining activities.

Rapid assessment procedures of malaria in low endemic countries: community perceptions in Jepara district, Indonesia.

Most studies on community perceptions toward malaria have been undertaken in high-endemic countries, and studies from low-endemic countries have only recently been published. Similar information is also needed for hypoendemic countries such as Indonesia, to cope with the persistence of foci-endemic malaria in these regions. An applied qualitative method, Rapid Assessment Procedures, was employed during a 3-month intensive data collection period in Jepara district, Central Java province. Data were retrieved from 38 free-listings, 28 in-depth interviews, seven focus group discussions and unstructured observation. Qualitative thematic content analysis was applied. In this community, malaria (known as katisen or panas tis) was considered a common but minor illness. Insufficient understanding of malaria signs and symptoms in the subvillages likely leads to delay in illness recognition and treatment; not surprisingly self-treatment is common and the dosage most likely below the recommended dose. The health center was used but when it did not work, most people would shift back to traditional services due to cost considerations. Low understanding and acceptance of the causal link between the mosquito and malaria, likely leading to poor comprehension of preventive activities, as well as confusion of malaria with dengue fever, were identified. In conclusion, this study highlights a consistent gap between the common understanding and the biomedical description of malaria. If case management continues to be the main strategy in malaria control program, the emic perspective of the people must be well-integrated into the program. Likewise, interventions to improve home-treatment should also be developed.

Generating political will for safe motherhood in Indonesia.

In 1987 an international conference brought global attention to an issue that previously had been ignored: the world's alarmingly high number of maternal deaths in childbirth. The conference ended with a declaration calling for a reduction in maternal mortality by at least half by the year 2000. As the deadline approached, safe motherhood activists lamented the fact that the world was nowhere near to achieving this objective. They attributed this failure to a variety of causes, but were in agreement that the medical technology was available to prevent maternal deaths in childbirth, and the key was generating the political will to make such technology widely available to women in developing countries.What 'political will' means, however, has been left as an unopened black box. What causes governments to give priority to the issue of safe motherhood, given that national political systems are burdened with thousands of issues to sort through each year? In marked contrast to our extensive knowledge about the medical interventions necessary to prevent maternal death, we know little about the political interventions necessary to increase the likelihood that national leaders pay meaningful attention to the issue. Drawing from a scholarly literature on agenda setting, this paper identifies four factors that heighten the likelihood that an issue will rise to national-level attention: the existence of clear indicators showing that a problem exists; the presence of effective political entrepreneurs to push the cause; the organization of attention-generating focusing events that promote widespread concern for the issue; and the availability of politically palatable policy alternatives that enable national leaders to understand that the problem is surmountable. The paper presents a case study of the emergence, waning and re-generation of political priority for safe motherhood in Indonesia over the decade 1987-1997, to highlight how these four factors interacted to raise safe motherhood from near obscurity in the country to national-level prominence. While there are contextual factors that make this case unique, some elements are applicable to all developing countries. The paper draws out these dimensions in the hope that greater knowledge surrounding how political will actually has been generated can help shape strategic action to address this much neglected global problem.

Characterisation of the 33kDa piroplasm surface antigen of Theileria orientalis/sergenti/buffeli isolates from West Java, Indonesia.

The immunodominant 33/35kDa antigen of a Theileria isolate from West Java, Indonesia, was characterised and immuno-affinity purified by use of a monoclonal antibody, KUL-a4, and was shown to be representative of the T. orientalis/sergenti/buffeli group. The aminoterminal sequence of the purified 35kDa peptide (20 residues) was determined by automated Edman degradation and found to correspond to the predicted amino acid sequence of a prospective p33 gene previously sequenced from the same isolate. The cleavage site of a putative signal peptide was identified and conforms the (-3, -1) rule for signal peptidases. The existence of dimeric and trimeric forms of the p33/35 antigen is hypothesised from Western blot profiles. KUL-a4 appeared specific for the T. orientalis/sergenti/buffeli group. It did not recognise in indirect fluorescence antibody test (IFAT), intraerythrocytic bodies of Anaplasma marginale or piroplasms and schizonts of T. mutans, T. parva and T. annulata, whereas cattle antisera raised to these species showed cross-reactivity in IFAT. It however, appeared weakly cross-reactive in Western blot and ELISA, with the 34kDa piroplasm antigen of one T. annulata (Gharb) isolate. The present study indicates that the isolated antigen belongs to the p33/34 antigen family described within the T. sergenti/orientalis/buffeli group, and documents the group-specificity of one of its epitopes.
