Estimation of the prevalence of lymphatic filariasis by a pool screen PCR assay using blood spots collected on filter paper.

The prevalence of lymphatic filariasis was estimated by PCR-based pool screening of night blood collected from 865 individuals living in ten areas endemic for Wuchereria bancrofti, Brugia malayi or B. timori in Indonesia. A total of 232 microfilaraemics were identified by filtration of 1 ml of blood.

Impact of two rounds of mass drug administration using diethylcarbamazine combined with albendazole on the prevalence of Brugia timori and of intestinal helminths on Alor Island, Indonesia.

Background: Annual mass drug administration (MDA) using diethylcarbamizine (DEC, 6 mg/kg) combined with albendazole (alb, 400 mg) is recommended by the Global Programme to Eliminate Lymphatic Filariasis (GPELF). This strategy has been shown to be efficient in the of control bancroftian filariasis, but data on brugian filariasis as well as on the positive side effects on intestinal helminths are lacking.

Methods: The effect of one selective treatment and two rounds of MDA using DEC and alb on the prevalence and intensity of Brugia timori infection were studied on Alor island using a cross-sectional and a cohort approach.

Risk factors for transmission of foodborne illness in restaurants and street vendors in Jakarta, Indonesia.

In a previous risk factor study in Jakarta we identified purchasing street food as an independent risk factor for paratyphoid. Eating from restaurants, however, was not associated with disease. To explain these findings we compared 128 street food-vendors with 74 food handlers from restaurants in a cross-sectional study in the same study area.

Long-lasting reduction of Brugia timori microfilariae following a single dose of diethylcarbamazine combined with albendazole.

The long-term effect of a single oral dose of 6 mg/kg bodyweight of diethylcarbamazine (DEC) combined with 400 mg albendazole (ALB) on the microfilariae (mf) of the lymphatic filarial parasite Brugia timori was studied on Alor island, Indonesia from April 2001 to April 2002. Before treatment the geometric mean of the mf density in 96 infected study subjects was 150 mf/mL night blood (range 1-5696 mf/mL). One year after treatment 69 subjects (72%) were mf-negative and the overall geometric mean mf density reduced to 3 mf/mL (0-2456 mf/mL).

PCR-based detection and identification of the filarial parasite Brugia timori from Alor Island, Indonesia.

Brugia timori is widely distributed on Alor Island, Indonesia, where it causes a high degree of morbidity. The HhaI tandem repeat of B. timori was found to be identical to that of B.

Treatment of Brugia timori and Wuchereria bancrofti infections in Indonesia using DEC or a combination of DEC and albendazole: adverse reactions and short-term effects on microfilariae.

Filariasis caused by Brugia timori and Wuchereria bancrofti is an important public health problem on Alor island, East Nusa Tenggara, Indonesia. To implement a control programme, adverse reactions and short-term effects on the microfilaria (mf) density were studied following a divided dose of diethylcarbamazine (DEC, 6 mg/kg body weight - 100 mg on day 1 and the rest on day 3) or a single dose of DEC (6 mg/kg body weight on day 3) and albendazole (Alb, 400 mg). In order to define the most appropriate regimen, 30 persons infected with B.

High prevalence of Brugia timori infection in the highland of Alor Island, Indonesia.

To identify areas endemic for Brugia timori infection, a field survey was carried out in 2001 on Alor, East Nusa Tenggara Timor, Indonesia. Elephantiasis was reported on this island by villagers as a major health problem. Bancroftian filariasis was detected in four villages in the coastal area, whereas B.

The effect of intervention methods on nutritional status and cognitive function of primary school children infected with Ascaris lumbricoides.

The prevalence rate of ascariasis in primary school children in northern Jakarta, Indonesia varies from 60% to 90%. An association between helminthic infection and educational achievement has long been recognized. This study was carried out in the northern part of Jakarta among primary school children 6-8 years of age.

The effect of praziquantel treatment on liver and spleen size of children with schistosomiasis in Napu Valley, central Sulawesi.

Forty-six school children with japonicum schistosomiasis living in a village at Napu Valley, Indonesia were treated with praziquantel at a dosage of 70 mg/kg in two divided doses in a day. The number of children with palpable liver dropped significantly from 95.6% before treatment to 58.

The impact of schistosomiasis mass treatment on hepato-splenomegaly in Napu Valley, Central Sulawesi, Indonesia.

The impact of mass treatment with praziquantel on 241 individuals, 131 males and 110 females in Napu Valley, Indonesia was studied. The pre-treatment overall stool positive cases ranged from 43% to 79%, the highest in the 20-29 age group. Post-treatment follow-up study showed that the cases dropped to 2.

Prevalence and treatment of intestinal helminthic infections among children in orphanages in Jakarta, Indonesia.

A survey was carried out in three orphanages in Jakarta for intestinal helminthic infections. Stool samples and anal swabs of 158 children were examined. The prevalences of intestinal helminthic infections in the Putra Utama, Muslimin and Van der Steur orphanages were respectively as follows: a lumbricoides 70.
