Prevalence of the coccidian protozoa, genus Sarcocystis, parasite of rat and their predators in oil palm, was studied during the year 1995 to 1996. The animals were trapped 6 times from 6 oil palm plantations in the southernpart of Thailand ; Thambol Bangson Amphor Pra Thue, Thambol Hongcharoen Amphor Tha Sae, Changwat Chumporn ; Surat Thani Horticultural Research center, Changwat Surat Thani ; Thambol Krabinoi Amphor Muang, Thambol Khaokaen Amphor Auw Lok, Changwat Krabi and Amphor Kuan Galoeng Changwat Satul. The coccidian protozoan were collected from muscles at limb and trunk of the 4 rat-species, the Malayan wood rat. Rattus tiomanicus, the Malayan house rat, R. rattus diadii, the Mueller rat, R. mueller, and the grea bandicoot, Bandicota indica. Moreover the feces of the rat-predators (snakes, such as, the cooperhea(racer, Elaphe radiata, the siamese cobra, Naja kaouthia, and common palm civet, Paradoxuru hermaphoroditus) were also examined. There were 197 rats and 7 predators (4 copperhead racers, 2 siamese cobras and 1 common palm civet) examined in this study. Five species and one unknown of Sarcocystis were found only in 82 rats. There are Sarcocystis singaporensis, S. zamani, S.cymruensis, S. villivillosi, S. (Type) murinotechis, and S. sp.. Sarcocysts in the muscles of the Malayan wood rats, the Malayan house rats, the great bandicoot and the Mueller rat were found 62.19, 32.92, 3.66, 1.22 percent, respectively. However, the cysts of S. singaporensis were more prevalent than those of other species. In the feces of rat predators, only 2 racers had sporocysts of Sarcocystis.
