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.
