Peri-parturient rise in faecal strongyle egg counts of different genotypes of sheep in North Sumatra, Indonesia.

Faecal strongyle egg counts were monitored in peri-parturient ewes and dry ewes grazing in a rubber plantation in North Sumatra, Indonesia. A significant rise in faecal egg counts was observed during the post-parturient period. Haemonchus contortus was the dominant species in the faecal cultures of the lactating ewes. The intensity of the peri-parturient rise was affected by the genotype of the sheep, which were the local Sumatra and its F1 crosses with St. Croix, Barbados Blackbelly and Java Fat-tail. The peri-parturient rise in egg counts was highest in Sumatra and lowest in the Barbados Blackbelly x Sumatra cross. A significant effect of litter size on the peri-parturient rise was also demonstrated. These findings are discussed in relation to the epidemiology and control of gastrointestinal nematodes in the humid tropics.

The immunogenicity and pathogenicity of Pasteurella multocida isolated from poultry in Indonesia.

Of 13 field isolates of Pasteurella from chickens and ducks in Indonesia, 10 were confirmed as P. multocida subspecies multocida, one as P. multocida subspecies gallicida and one as P. multocida subspecies septica. Nine were capsular Type A four were Serotype 1, one was Serotype 4, one was Serotype 11, one was Serotypes 4,12, and the remaining six were untypable. Five isolates were pathogenic for mice and two were pathogenic for chickens. Both a trivalent vaccine which included local field isolates and an imported commercial vaccine, were efficacious in layer chickens against challenge with virulent reference and local field strains. Though not statistically significant, the protection provided by the trivalent vaccine against virulent field isolate challenge was slightly better and could provide an improvement over the currently used imported vaccine although further field trials are required. A bacterin vaccine produced from a Serotype 1 field isolate grown in the allantoic sac of embryonated chicken eggs provided chickens with good cross protection against heterologous serotype challenge.

Jamu Gendong, a kind of traditional medicine in Indonesia: the microbial contamination of its raw materials and endproduct.

An examination on the microbiological quality of seven kinds of Jamu Gendong (JG) and their raw materials has been conducted according to the requirements of microbial contamination in traditional medicine, issued by the Department of Health of Indonesia in 1986. Samples of JG and their raw materials were taken from producers in three districts of Surabaya. The samples were subject to the following examinations: total plate count (TPC), MPN coliform, the enumeration of molds and yeasts, the presence or absence of Staphylococcus aureus, Salmonella and Vibrio. Each time the JG samples were taken from different producers together with their raw materials. The results of this investigation showed that most of the JG samples were heavily contaminated with bacteria, yeasts and molds. For bacteria, taken from the TPC results, their numbers were ranging from 7.7 x 10(2) microorganisms/ml to too many to count (TMTC). For yeasts and molds the numbers showed variations from 0 microorganisms/ml to TMTC. Contamination with Coliform in 1 ml of JG were ranged from 0 to > 2.4 x 10(6) microorganisms. In most of the samples pathogenic Staphylococci, Salmonella sp. and Vibrio sp. were not detected, so that a conclusion can be drawn that most of the contamination in JG are saprophytic, only a few pathogenic. The results also show that it is possible to have JG which fulfill the government's requirements. Similar results were obtained with the plant material constituents of JG such as rhizomes, leaves, herbs and fruits of Piper nigrum and Piper retrofractum, with the exception of Piper betle leaves and P. retrofractum fruits, both showing low contamination of Coliform bacteria. However, the fruits of Citrus aurantifolia and Morinda citrifolia were less contaminated, just like seeds of Oryza sativa, Parkia roxburghii, bulbs of Allium sativum and the pulp of Tamarindus indica. With these plant constituents of JG, it might be of interest to screen their antibacterial and antifungal activities.

Vibrio parahaemolyticus associated with cholera-like diarrhea among patients in North Jakarta, Indonesia.

A diarrhea study was conducted in North Jakarta, Indonesia from December 1996 through December 1997. Vibrio parahaemolyticus was isolated from 333 (6.1%) of 5442 rectal swab samples collected from patients with cholera-like diarrhea. Vibrio cholerae O1 was isolated from 545 (10.0%) and V. cholerae non-O1 from 183 samples (3.4%), respectively. Patients positive for V. parahaemolyticus were mostly adults between 20 and 40 years of age, with males constituting 62%. A majority (65%) of these patients demonstrated watery diarrhea with a frequency of fewer than 10 episodes per 24 hour. A large number of the patients had abdominal pain (83%) and vomiting (76%) and were non-febrile (90%). The highest isolation rate (9.6%) of V. parahaemolyticus was found during the dry season (June, July) and the lowest (4.5%) in the rainy season (December, January, February). All of the V. parahaemolyticus isolates were hemolytic on human blood agar (positive Kanagawa) but none was urease positive. Disk diffusion antibiotic susceptibility tests performed on the isolates demonstrated resistance to ampicillin (98%), cephalothin (24%), kanamycin (15%), colistin (97%), neomycin (2%) and ceftriaxone (0.3%). All isolates (100%) were sensitive to chloramphenicol, tetracycline, trimethoprim-sulfamethoxazole, gentamicin, and ciprofloxacin.

Client communication behaviors with health care providers in Indonesia.

Patient participation in health care consultations can improve the quality of decision making and increase patients' commitment to the treatment plan. This study examines client participation, operationally defined as client active communication, during family planning consultations in Indonesia. Data were collected on 1203 consultations in the provinces of East Java and Lampung. Sessions were audiotaped and the conversation coded using an adaptation of the roter interaction analysis system (RIAS). Culturally acceptable ways for Indonesian clients to participate in consultations include asking questions, requesting clarification, stating opinions, and expressing concerns. Factors significantly associated with client active communication were, in order of importance, providers' information giving, providers' facilitative communication, providers' expressions of negative emotion, client educational level, and province. The latter suggests the influence of culture on client participation. The results suggest that a combination of provider training and client education on key communication skills could increase client participation in health care consultations.

Participation by clients and nurse midwives in family planning decision making in Indonesia.

In order to enhance understanding of the quality of decision making during family planning consultations in developing countries, provider competencies and client behaviors during 179 randomly selected consultations in Indonesia were assessed. Results show that family planning clients make a significant contribution to the quality of the decision-making process, most notably by identifying the problem requiring a decision, expressing their feelings about using a method, and asking questions. Client involvement may compensate for provider weaknesses, which tend to be in areas calling for interpersonal rather than technical skills. However, the programmatic ideal of informed choice has not yet been realized. Supervisors, trainers, communicators, and program managers can improve the quality of decision making by: creating opportunities for client involvement during consultations, strengthening providers' ability to fully inform clients about their options, and making providers aware of the opportunities for decision making in consultations with continuing clients.

Serotyping and further characterization of group B streptococcal isolates from Indonesia.

Serotyping of 103 streptococci of serological group B isolated from human clinical specimens in Indonesia revealed mainly type pattern Ia/c and type patterns III and V, either alone or in combination with protein antigens c or R. Few cultures had serotype II and IV, none of the cultures had type antigen Ib or X. Extracts of one group B streptococcal culture reacted with antibodies specific to type antigens II, IV and R and one culture with antibodies specific to candidate type 7271. Protein antigen c was present as c alpha, c alpha, beta but not as c beta component. Group B streptococci with type antigen R grew generally as a granular sediment with clear supernatant, formed compact colonies in soft agar and reacted positively in the salt aggregation test. Group B streptococci without surface antigen R grew mainly with a uniform turbidity of the growth media, formed diffuse colonies in soft agar and were negative in the salt aggregation test.

Youth, sexuality and sex education messages in Indonesia: issues of desire and control.

Since the 1994 International Conference on Population and Development, the need for sexuality education for youth has been articulated, and numerous activities in Indonesia, especially Java, have been directed at young people. However, many parents, teachers and religious leaders have considered it essential that such education should suppress youth sexuality. This article reflects upon current discourses on youth sexuality in Java as against the actual sexual behaviour of young people. Using examples from popular magazines and educational publications, and focus group discussions with young men and women in Surabaya, East Java, we argue that the dominant prohibitive discourse in Java denounces youth sexuality as unhealthy, reinforced through intimidation about the dangers of sex. In contrast, a discourse of competence and citizenship would more adequately reflect the actual sexual behaviour of youth, and raises new challenges for sexuality education. Information should be available to youth concerning different sexualities, respecting the spectrum of diversity. Popular youth media have an especially important role to play in this. The means to stay healthy and be responsible--contraceptives and condoms--should be available at sites where youth feel comfortable about accessing them. Meanwhile, young Indonesians are engaging in different forms of sexual relationships and finding their own sources of information, independent of government, religion and international organisations.

Stillbirth, neonatal death and reproductive rights in Indonesia.

Globally, newborn deaths account for two-thirds of all deaths in the first year of life and 40% of under-five mortality. As infant mortality declines, the proportion of neonatal deaths has been increasing because of the failure to address the causes. The data in this paper derive from a longitudinal study of motherhood and emotional well-being of women in Indonesia; 488 women were interviewed in late pregnancy, and 290 at six weeks post-partum. This paper reports on in-depth interviews with four women who reported a stillbirth and six who reported a neonatal or infant death. They were asked about their understanding of why their baby had died and the information, care and support given to them. The study suggests that maternal and child health clinics fail to protect and fulfill pregnant women's reproductive rights, specifically the right to information and care for themselves and their infants, informed consent, counselling and to be treated with respect. This can be achieved through training and education for health professionals and policymakers, and by educating women about their rights as patients. It is essential that countries with high infant and maternal mortality provide post-partum care that includes support for those who experience stillbirth and neonatal death, including information, counselling and home visits.

Breast-feeding and post-partum amenorrhoea in Indonesia.

The association between breast-feeding patterns and resumption of menses post-partum was examined in a prospective study in Indonesia. In order to examine these relationships directly in a longitudinal study, it was first necessary to distinguish among women who experienced infant mortality before menses resumed, women who weaned before menses resumed, and women who had return to menses while breast-feeding. Information on suckling patterns and menstrual status was collected by recall for 444 women at monthly visits for 2 years. Three main breast-feeding variables, minutes per episode, number of episodes per day, number of episodes per night, and other breast-feeding variables were derived for each woman, to give the average nursing pattern up to menses or the end of the study, which-ever came first. While high levels of nursing for each of these three main variables were found to be significantly related to delay in return of menses post-partum, the interactions between more minutes per episode, and more frequent day- and night-time feeds, were found to be the most important factors in the delay in onset of post-partum menstruation in those women whose menses resumed while still nursing or who remained amenorrhoeic and nursing at the end of the study.

Significant effects of birth-related biological factors on pre-adolescent nutritional status among rural Sundanese in West Java, Indonesia.

The Sundanese inhabiting West Java, the second largest ethnic group in Indonesia, are characterized by a high prevalence of child malnutrition, together with high fertility. Based on an anthropometric measurement and interview survey of 310 children aged 5-12 years in a rural Sundanese village, this study examined the relative significance of the effects of eight biological, eight socioeconomic status (SES) and four health behavioural factors on their Z scores for height-for-age (HAZ) and weight-for-age (WAZ) in particular. Three biological factors, i.e. birth interval, birth weight and mother's body weight, and one SES factor, i.e. mother's occupation, were selected as the predictors of the two Z scores by regression analysis, indicating more significant effects of the biological factors than the other factors. This pattern is judged to occur in less-developed and high-fertility populations. Since these two Z scores were worse in the subject children than in the under-5-year-old children from the same village, more attention should be paid to the long-lasting effects of birth-related biological factors up to pre-adolescent ages, as an insufficient nutritional status tends to damage growth and health in adolescence and adulthood.

Occurrence and distribution of the entomopathogenic nematodes Steinernema spp. and Heterorhabditis indica in Indonesia.

Soil samples from 79 sites on five islands of Indonesia were baited with insects for the recovery of entomopathogenic nematodes. Heterorhabditis and Steinernema were equally prevalent, and were recovered from 11.7% of samples representing 20.3% of sites sampled. Both genera were recovered from coastal sites only. Entomopathogenic nematodes were more prevalent on the Moluccan islands of Ambon and Seram than on Java or Bali. They were not detected on Sulawesi, where non-coastal sites only were sampled. RFLP analysis was used in the identification of nematode isolates. Heterorhabditis indica was the only heterorhabditid identified. Two RFLP types of Steinernema were identified.

Salmonellosis in Indonesia: phage type distribution of Salmonella typhi.

The distribution of phage types was studied among 577 strains of Salmonella typhi from Indonesia. Chemotype, colicinogeny, and tetrathionate reductase activity were also studied for most of these strains. The current phage type formula for Java was determined to be: A, D2, D6, E1a, E2, M1, and 46, but two other large groups of strains were also found, I + IV and degraded Vi+ strains. Significant differences in S. typhi strain distributions were noted between two localities on Java with respect to phage type and tetrathionate reductase activity. Comparisons were made with past phage typing studies in Jakarta as well as with more recent studies in other parts of south-east Asia. Phage types A, D1, D2, and E1 persisted at a rather steady level in Jakarta for 28 years. Evidence was found for epidemiological links to European and Asian areas. Antibiotic resistance among these Indonesian S. typhi strains was rare.

Salmonellosis in Indonesia: phage type distribution of Salmonella paratyphi A.

The distribution of phage types among 221 human strains of Salmonella paratyphi A in Indonesia was studied. Approximately 50% were phage type 5, a rare type elsewhere in the world. Most other isolates were the cosmopolitan phage type 1. The ratio of phage type 1-5 was compared for two cities on Java, Jakarta and Yogyakarta. The ratios were significantly different, phage type 5 predominating in Jakarta. The ratio of phage types among 10 S. paratyphi A strains isolated from Jakarta river water was similar to that found in Jakarta patients.

DNA comparisons of Trypanosoma evansi (Indonesia) and Trypanosoma brucei spp.

Two clones from separate isolates of Trypanosoma evansi in Indonesia were found by polymerase chain reaction (PCR) analyses to contain 3 different repeated nuclear DNA sequences of Trypanosoma brucei spp: the consensus sequence for a highly repetitive 177 base pairs and the gene repeats encoding procyclin and the spliced leader. In addition, the 994 bp minicircle sequence of one of the clones was determined, and PCR amplification primers specific for minicircles of T. evansi were identified that do not amplify minicircle sequences in the T. brucei spp. clones tested.

A self-fertile species of Steinernema from Indonesia: further evidence of convergent evolution amongst entomopathogenic nematodes?

More than 20 species of the entomopathogenic nematode Steinernema have been described; to date, all reproduce exclusively by cross-fertilization of male and female individuals. Steinernema sp. strain T87 from Indonesia was found to consist largely of self-fertile hermaphrodites. Progeny were produced by morphological females both in insects (Galleria mellonella) and in hanging drops of insect haemolymph inoculated with a single infective juvenile. Sperm were present in the oviduct of unmated morphological females. Approximately 1% of infective juveniles developed into males, and males were also present in the second generation where they constituted 1-6% of the population. Under the same conditions the related species Steinernema longicaudum strain CB2B displayed typical steinernematid reproduction: cross-fertilization and a 1:1 sex ratio. It is argued that the development of hermaphroditism in Steinernema sp. T87 represents convergent evolution with Heterorhabditis, the other major genus of entomopathogenic nematode.

Clustering of Brugia malayi infection in a community in South-Sulawesi, Indonesia.

The present study was undertaken in village Karondang in South-Sulawesi, Indonesia, to investigate the influences of genetic, household and environmental factors on Brugia malayi infection. Infection status was determined by measuring both microfilariae in night blood and anti-filarial IgG4, as a marker for detection of active filarial infection. A total of 171 residents participated in the study; familial relationships between subjects were registered to construct pedigrees and distances between households were measured. The data were analysed using a test statistic for familial aggregation. For distribution of microfilariae over the study population a genetic influence on infection susceptibility was favoured over the household and environmental effects. For anti-filarial IgG4, all 3 clustering models gave significant results, suggesting that genetic, household and/or environmental factors influence specific IgG4 antibodies.
