A study of malayan filariasis in Lubuk Mumpo and Datar Lebar villages in Lais Regency, North Bengkulu, Sumatera, Indonesia.
Filariasis surveys at Lubuk Mumpo and Datar Lebar, Bengkulu, Sumatera, showed microfilarial rates of 23.9% and 30% respectively. Periodicity studies showed the parasite to be nocturnally periodic B. malayi with a periodicity index of 82.17. However, unlike the Malaysian form of periodic B. malayi, 44-100% of the microfilariae in thick blood smears were sheathed. Mansonia annulata, M. bonneae, M. dives, M. uniformis and Anopheles nigerrimus are probably involved in the transmission of the disease. B. malayi infections were seen in 7.1% of domestic cats and 20% of Macaca fascicularis examined. In addition Edesonfilaria malayensis is reported for the first time in Indonesia, 60% of 5 M. fascicularis being infected.
