Distribusi Habitat Oncomelania hupensis lindoensis, Keong Perantara Schistosoma japonicum di Dataran Tinggi Lindu, Kabupaten Sigi, Sulawesi Tengah

---

Oncomelania hupensis lindoensissnail and its habitat has an important role in the transmission of schistosomiasis in Central Sulawesi, particularly in three isolated areas, Lindu valley, Napu valley and Bada valley. In a part of Schistosomiasis life cycle, inside the snail, Schistosoma japonicummiracidia will undergo a series of stages as sporocyst and cercaria. People are infected by cercaria, the infective stage of S. japonicum.

This study were conducted to reconfirm the distribution of O. h. lindoensishabitats in Lindu valley area. The snails were searched and collected in the suspected habitat using ring-sample and man per minute methods by skilled staffs from VBDRU Donggala and Schistosomasis laboratory plus trained local people in the collections. Data on the distribution of snail habitats were recorded by using GPS. Snails and vegetation in the habitats were collected for further analysis in the laboratory.

A total of 129 snail habitat were recorded in Lindu valley, consisting of 135 old foci and 1 new focus. In this area, a total of 61 foci are still active of snail habitats. Foci are distributed in several types of habitat, i.e. abandon rice fields, ditches, springs, dry farming, shrubs and forest. Each type habitat has a relative similar vegetation species. The infection rates of O. h. lindoensiswith cercariae in Anca, Tomado dan Puroo villages were 5.27%, 3.19% and 7.58% respectively. These results indicate that the Schistosomiasis transmission is still going on in Lindu valley.
