Abstract

A survey of prevalence of intestinal parasites among the local population of Lum Pra Due village in the Nakorn Ratchasrima province was performed during the year of 2000. The setting is a community in the endemic area of trematode infection without the recent previous history of antihelminthic drug distribution. Stool examination from 153 villagers (63 males and 90 females) was performed. The infection rate was 68 % (104 cases). The rate of infection in male (72 %) was higher than in female (62 %). Most of the infected cases (88 %) were in the age group 41 60 years. Single Opisthorchis viverrini infection was found in 7 cases. Combined infection of Opisthorchis viverrini with other non-fluke intestinal parasite was found in 44 cases. Combined infection of minute intestinal fluke with other non-fluke intestinal parasite was found in 85 cases. There were also 5 infected cases, but without fluke, with non-fluke parasite. Therefore, trematode infection is still a major health problem for this community.
