Cloning and characterization of human papillomavirus type 52 from cervical carcinoma in Indonesia.

Human papillomavirus (HPV) type 52 from a cervical carcinoma in Indonesia was molecularly cloned and characterized. By hybridization with cervical carcinoma DNAs from Indonesian patients, HPV 52 was detected in 3 of 52 cases (6%), whereas HPV 16 and 18 were detected in 8 and 7 cases, respectively (15% and 13%). Sequence analysis revealed that the E6-E7 ORFs contained several DNA binding motifs (Cys-X-X-Cys) like previously sequenced HPVs. The E6 ORF also contained splice donor and acceptor signals, which may allow the expression of E6* protein. The E7 ORF encoded an amino acid sequence that is conserved in some DNA tumor viruses and is involved in binding to Rb protein and in cellular transformation. Transfection of a subgenomic fragment of HPV 52 under the control of a heterologous promoter showed that the E7 ORF alone induced anchorage-independent growth of established rodent cells and immortalized primary rat embryo fibroblasts (REF), and that in cooperation with activated ras, it induced malignant transformation of REF. The E6 ORF also induced, less efficiently, anchorage-independent growth. These results strongly suggest that HPV 52, like HPV 16 and 18, has oncogenic potential.

Contraceptive practice after women have undergone "spontaneous" abortion in Indonesia and Sudan.

Studies of hospitalized "spontaneous" abortion patients in two Muslim countries (Indonesia and Sudan) revealed the need for contraception in this group of married women and indicated the potential role of maternity hospitals in providing them with contraceptive counseling. It could not be determined which of the abortions were induced outside the hospital and which were truly spontaneous. Of the 893 women treated at the Djakarta Hospital, 15.3% used contraceptives during the month of conception of the index abortion, compared to 10.0% of the 2 759 patients in Khartoum. After hospitalization for completion of the abortion, the rates of contraceptive use increased by more than one third in both cities. The highest rates of increase in contraceptive use after abortion were noted among poorly educated women, women with large families, and women with abortions diagnosed as septic. Among the nonseptic patients at all hospitals, those experiencing complications associated with the abortion reported a slightly higher rate of postabortion contraceptive use. In hospitals where contraceptive counseling was provided, there was a proportional increase in postabortion use of contraceptives by the study population.

Serological markers of hepatitis B, C, and E viruses and human immunodeficiency virus type-1 infections in pregnant women in Bali, Indonesia.

Except for hepatitis B virus (HBV), there have been few data on serological markers of hepatitis viruses such as hepatitis C virus (HCV) and E virus (HEV), and human immunodeficiency virus type-1 (HIV) in Bali, Indonesia. During 5 months from April to August 2003, sera were collected from 2,450 pregnant women at eight jurisdictions in Bali, and they were tested for markers of these viruses. Only one (0.04%) was positive for antibody to HCV, but none for antibody to HIV. Hepatitis B surface antigen (HBsAg) was detected in 46 (1.9%) at a prevalence significantly lower than that in 271 of the 10,526 (2.6%) pregnant women in Bali surveyed 10 years previously (P < 0.045). The prevalence of hepatitis B e antigen in pregnant women with HBsAg decreased, also, from 50% to 28% during the 10 years (P < 0.011). Antibody to HEV (anti-HEV) was examined in 819 pregnant women who had been randomly selected from the 2,450. The overall prevalence of anti-HEV was 18%, and there were substantial regional differences spanning from 5% at Tabanan district to 32% at Gianyar district. Furthermore, the prevalence of anti-HEV differed substantially by their religions. In the Sanglah area of Denpasar City, for instance, anti-HEV was detected in 20 of the 102 (20%) Hindus, significantly more frequently than in only 2 of the 101 (2.0%) Muslims (P < 0.001). Swine that are prohibited to Muslims, therefore, is likely to serve as a reservoir of HEV in Bali. In conclusion, HBV is decreasing, HCV and HIV have not prevailed, as yet, while HEV is endemic probably through zoonotic infection in Bali.

Associations between trace metals in sediment, water, and guppy, Poecilia reticulata (Peters), from urban streams of Semarang, Indonesia.

The present study aims to answer the question whether the amount of metal in aquatic biota reflects the concentrations in the sediment and water, and whether the physico-chemical properties of the water and sediment have any influence on the suspected relationship. A study was made of 101 small streams in the city of Semarang, Central Java, Indonesia. Data on fish occurrence in 63 streams of the greater Semarang indicated that the guppies did not avoid the highly polluted sites. No significant difference in body weight between sites was found. Significant differences were found in metal body concentrations (Pb and Zn) between fish collected from sites with different degrees of pollution. A significant declining trend of Pb concentrations with increasing organism size was observed, whereas for two other metals, Zn and Cu, the concentrations did not depend on the body weight. Apparently, body concentrations of these two metals are regulated and maintained at a certain concentration. For the relationships between metal concentrations in water, sediment and fish, water and sediment parameters, and fish dry weight, the presence of significant multiple correlations and bivariate correlation (in 17 of 91 pairs of variables) indicated that, in general, abiotic parameters and body size had no influence on the metal flux from sediment to water, and into fish. Results of partial correlation analyses further suggested that metal concentrations in the sediments were the most important factor governing the metal body concentrations of fish. The present study indicates that the guppy Poecilia reticulata from urban streams is a potential bioindicator for urban metal pollution, especially with respect to their (1) spatial distribution over sites of all pollution regimes and (2) variation in metal accumulation levels reflecting the degree of pollution.

Characterization of a single-nucleocapsid nucleopolyhedrovirus of Thysanoplusia orichalcea L. (Lepidoptera: Noctuidae) from Indonesia.

A single-nucleocapsid nucleopolyhedrovirus (NPV) isolated from Thysanoplusia orichalcea L. (Lepidoptera:Noctuidae) (ThorNPV) in Indonesia has tetrahedral occlusion bodies (OBs) with a width of 1. 22 microm (range = 0.803-1.931 microm). The length of the virion with an envelope averaged 0.29 and 0.23 microm without an envelope. ThorNPV was propagated in Pseudoplusia includens (Walker) and its authenticity was confirmed by sequence analysis of the polyhedrin gene of the ThorNPV produced in T. orichalcea and P. includens. Polyhedrin amino acid sequence analysis revealed that ThorNPV belongs to Group II of baculoviruses and is closely related to Trichoplusia ni single nucleocapsid NPV, sharing 97.6% sequence identity. Infectivity of ThorNPV against third instar P. includens was low, with a LD(50) value of 65,636 OBs/larva. Electron microscopy of infected tissues showed many polyhedra without virions embedded, which might explain the low virulence against P. includens. Differences in virion occlusion rates between individual cells in the same tissue suggested that the inoculum consisted of at least two variants that differed in the gene(s) controlling virion occlusion. In a host range test using the LD(50) value to P. includens against Spodoptera exigua, S. frugiperda, S. eridania, Anticarsia gemmatalis, Helicoverpa zea, Trichoplusia ni, and P. includens, P. includens was the only species infected. The virus infected primarily the fat body, tracheal epithelium, and hypodermis. The genomic size of the ThorNPV is 135 kb.

Coltiviruses isolated from mosquitoes collected in Indonesia.

Viruses with genomes consisting of 12 segments of double-stranded (ds) RNA were isolated from mosquito pools collected in Indonesia in 1980 and 1981. The genome segments of 11 virus isolates exhibited two distinct electrophoretic patterns in agarose gels, and the viruses probably represent distinct groups of Coltiviruses. Ten of the 11 virus isolates produced recognizably similar PAGE profiles of two groups of 6 segments (6-6) with 3 distinct profile variants, and the remaining virus isolate displayed a unique 6-5-1 profile. These profiles were distinct from that of Colorado tick fever (CTF) virus RNA. The genetic relatedness of the isolates was examined by RNA-RNA hybridization. The viruses with a 6-6 profile were closely related in the majority of their segments, with segments 7, 11, and 12 being variant; and segment 9 the most divergent. The segments of the virus with the unique PAGE profile (6-5-1) did not cross-hybridize with any of the other viruses. Similarly, RNA from virus isolates from Indonesian did not cross-hybridize with the segments of CTF virus. These data indicate that two additional genotypes are present in the Coltivirus genus.

Transmission profile of hepatitis B virus infection in the Batam region, Indonesia. Evidence for a predominantly horizontal transmission profile.

The aim of this study was to describe the distribution of hepatitis B virus markers among the autochthonous and immigrant multicultural populations of Riau province, Indonesia, in order to define the groups at risk and their infrastructure. This investigation was part of a large hepatitis B vaccination study. A total of 9701 healthy individuals, aged 5 years or older and living in the urbanised area of Batam, near Singapore, and on the surrounding islands were included. Socio-epidemiological data were collected, blood was drawn, and sera were tested for antibodies to hepatitis B core (anti-HBc) and surface antigen (anti-HBs). Anti-HBc-positive sera were tested against hepatitis B surface antigen (HBsAg). All tests comprised immunoassays from Roche (Germany) using Elecsys 2010. Complete data were available from 9314 subjects. The results showed relatively low prevalences of anti-HBc (a marker of a previous hepatitis B infection) and HBsAg in the 5-year-old chiLdren (5.8 and 1.9%, respectively) that increased continuously with increasing age. High anti-HBs levels (>1000 IU/L) were found in all age cohorts, indicating a lifelong threat of active hepatitis B infection. In conclusion, the transmission profile of hepatitis B appeared to be mainly horizontal (person-to-person) in the highly endemic region studied. Vertical transmission was less than 5%. The horizontal transmission routes included non-sexual activities of life since children <10 years of age also showed considerable infection rates. The results underline the need for catch-up hepatitis B vaccination programs for children and adults.

Mental health services and traditional healing in Indonesia: are the roles compatible?

This study reports on the presentation of illness complaints by 90 individuals to nine traditional healers in three Indonesian cities. Focus is on the nature of problems, client explanations and expectations, healer treatment and subsequent outcome as judged by clients. Selected clients were observed and interviewed by a psychiatrist and one other health professional, and followed in a subsequent home visit. Complaints were categorized according to dimensions of acuteness and chronicity of problem, presumed self-limited characteristics, and psychological, general medical and other factors. Sixty-five percent of all clients had received prior treatment for the same problem in a biomedical health care setting. The study holds practical implications for policies regarding relations between health and mental health services and traditional healers in Indonesia.

Indignant suicide in the Pacific: an example from the Toraja Highlands of Indonesia.

This paper describes and analyzes a type of Toraja (South Sulawesi, Indonesia) suicide in which a person kills him or herself after having been slighted or offended, usually by a close family member. Comparing and contrasting such suicides to similar types found elsewhere in Austronesia-speaking Oceania, the paper argues that self-inflicted deaths of this nature are not so much 'anomic,' as suggested by some analysts, as 'indignant'; they are committed by persons who feel that they have been severely mistreated or abused according to traditional notions of reciprocity, mutual aid, and the dangers of frustrated desire. The paper concludes by suggesting that Durkheim may have underestimated the frequency and importance of 'indignant' suicide in 'traditional' societies and that, conversely, contemporary analysts may be underestimating the importance of traditional norms and values in accounting for the high rates of suicide found in many parts of the Pacific today.

Product stewardship of Paraquat in Indonesia.

In Indonesia, paraquat products play an important role in controlling weed in plantation estates, small-holders farming land and potentially in tidal swamp areas to be converted to tidal rice farming. Laboratory and field data which showed that paraquat did not cause a health hazard to users/farmers if used normally or as recommended, and the virtual absence of environmental impact, were important information conveyed to the customers in the product stewardship activities. Education and training have been implemented in 11 provinces, covering 4934 farmers group, 206 Zeneca field staffs and 100 local government staffs since January 1993. Using interactive method and field practicals, significant improvements in the knowledge and skill of safe and effective use of pesticide have been achieved. The success of this stewardship initiative lies upon good relationship with government authorities and informal local leaders, besides careful planning.

Amino acid sequence differences in pancreatic ribonucleases from water buffalo breeds from Indonesia and Italy.

The amino acid sequences of the pancreatic ribonucleases from river-breed water buffaloes from Italy and swamp-breed water buffaloes from Indonesia differ at three positions. One of the differences involves a replacement of asparagine-34, with covalently attached carbohydrate on all molecules, in the river-breed enzyme by serine in the swamp-breed enzyme. The ribonuclease content of the pancreas differs considerably between breeds and is lower in river buffaloes. A ribonuclease preparation from two swamp buffaloes contained a minor glycosylated component. Preliminary evidence was obtained that the amino acid sequence of this component has factors in common with the main component of the swamp-breed ribonuclease and with the river-breed enzyme.

Genetic and biological differentiation of dengue 3 isolates obtained from clinical cases in Java, Indonesia, 1976-1978.

Previous epidemiological, virological and clinical studies have documented a series of outbreaks of dengue fever and dengue haemorrhagic fever/dengue shock syndrome which occurred in Java, Indonesia in 1976-1978. In the current study we compare growth characteristics in cell culture, and nucleotide sequence data for the viral prM and E genes, of five low passage DEN-3 isolates obtained during these epidemics from clinically defined cases. All isolates had the same passage history: human sera were passed twice in mosquitoes and three times in a mosquito cell line (Aedes albopictus, C 6/36 cells). Growth differences were observed between individual isolates in Vero cells; growth differences were not observed in C 6/36 cells. Nucleotide sequencing of the prM and E gene region indicated that no two isolates were identical (sequence divergence ranged from 0.4 to 1.6% in pairwise comparisons) but that they were closely enough related to present a single genetic type. There were one or two differences in deduced amino acid sequence in E between isolates. Differences were at residues 65, 187, 298 or 443. One isolate differed from all others at residue 16 in the M protein. No relationship was apparent between the amino acid sequence of M or E and the nature of the disease profile, the year of isolation or the geographic region of isolation. The isolates showed 3.5 to 4.4% nucleotide sequence divergence from the highly-adapted H 87 prototype, isolated in the Philippines in 1956. The isolates showed a total of twelve common amino acid differences in prM and E proteins from H 87. Ten of these twelve residues were at positions which differed between the four dengue serotypes. Two differences (at residues 37 in M and 293 in E) were at positions which are conserved in sequence between the four dengue serotypes. The data are discussed in relation to the dengue outbreaks in Java in the period 1976-1978.

Yaws in West Sumatra, Indonesia: clinical manifestations, serological findings and characterisation of new Treponema isolates by DNA probes.

The results of a yaws survey on the island of Sumatra in Indonesia are presented. The prevalence of yaws in the investigated region was found to be very high, a minimum of 300 cases per 100,000 individuals, which indicates that yaws is far from being eradicated and that campaigns for treatment are necessary. Patients suffering from early infectious yaws showed florid skin lesions. Of 101 serum samples from such patients, 100 had a positive reaction in one or more treponemal tests. The Treponema pallidum haemagglutination assay was found to be the most sensitive test (97% positive) in detecting antibodies against Treponema pallidum subsp. pertenue, followed by the fluorescent treponemal antibody absorption test (94%), the Venereal Disease Research Laboratory test and the TmpA enzyme immunoassay (91%), and analysis by Western blot using Treponema pallidum antigens (88%). Of 42 asymptomatic contacts of yaws patients 32 showed positive reactions in one or more tests, indicating that many people in the investigated region have been infected with treponemes. Eight new Treponema pallidum subsp. pertenue strains were isolated from yaws skin lesions. In vitro amplification of treponemal DNA and hybridisation with specific DNA probes showed that all eight strains were identical with Treponema pallidum subsp. pertenue CDC 2575, with regard to the subsp. pertenue specific tyfl gene.

Introductory trial of the once-a-month injectable contraceptive, Cyclofem, in Indonesia.

Cyclofem, a once-a-month injectable hormone contraceptive, contains medroxyprogesterone acetate, 25 mg and estradiol cypionate, 5 mg. Indonesia is one of the countries participating in an introductory trial in collaboration with the World Health Organization (WHO) under the Human Reproduction Program (HRP). The main purpose of the trial is to assess, through a limited cohort of users, both problems and user needs in the program situation with regard to safety, efficacy, acceptability, and causes of discontinuation in the Indonesian context. Data based on the trial (March 1990-February 1992) indicate that the Cyclofem women complained of dizziness, nausea, bleeding problems, migraine, vomiting, amenorrhea, allergies and hypertension during the use of Cyclofem. However, it was found that the complaint rates decreased with increased duration of use. The life table continuation rates indicate that about 80% and 66% continued use at the end of 6 months and 12 months, respectively. Personal reasons account for the highest proportion of discontinuation, followed by desire for pregnancy and lost-to-follow-up.

Use of ivermectin to control sarcoptic mange in goats in Indonesia.

The results of three experiments aimed at controlling sarcoptic mange in goats in Indonesia are reported. In Experiment 1 treatment with ivermectin (0.2 mg/kg body weight) or coumaphos (0.05% dip solution) resulted in a significant reduction in mite numbers and an increase in body weight while in the untreated controls all animals had to be withdrawn from the experiment due to severity of infection. In Experiment 2 three treatment levels of ivermectin were shown to be equally effective in reducing mite numbers, while again all untreated control animals were withdrawn. The third experiment demonstrated a significantly greater reduction in mite numbers following two doses of ivermectin at a seven day interval when compared to a single dose. Again the majority of untreated control animals were withdrawn. Future control strategies and reasons for failure to eliminate the presence of mites are discussed.

DIAG, a laboratory information management system developed for regional animal disease diagnostic laboratories in Indonesia.

The DIAG Laboratory Information Management System is a micro-computerised program designed for the use of regional and national animal disease diagnostic laboratories in Indonesia. It facilitates the day to day management of diagnostic data by monitoring the progress and turn round times of samples sent to laboratory sections and by printing outputs detailing the tests undertaken and results obtained. Notifiable disease reports are generated routinely as part of a national disease surveillance programme. Detailed analyses of specific diagnoses allow investigations of diseases over location and time. The database is easily accessed to allow additional analyses. Data entry is facilitated through the use of entry screens which reduce associated errors. The system is flexible and can readily be adapted to meet the demands of different countries, veterinary services and types of laboratory.
