ABSTRACT. Sambar (Rusa unicolor), Javan rusa (R. timorensis), and Philippine deer (R. marianna) were opportunistically fecal sampled in The Socialist Republic of Vietnam, in the Republic of Indonesia, and in the Republic of the Philippines, respectively, during 2022–2024. A total of 28 samples were analyzed. Eggs of trematodes of the superfamily Paramphistomoidea were found in R. unicolor faeces, larvae of nematodes of the family Protostrongylidae were found in R. timorensis faeces, egg of trematode of the family Fasciolidae was found in R. marianna faeces. Sample mean intensity of invasion was ≤ 12 trematode eggs per 1 g of faeces, < 1 nematode larva per 1 g of faeces, < 1trematode egg per 1 g of faeces, respectively. Sample prevalence was 75, 20, and 17%, respectively. Protostrongylids are reported for Javan rusa (R. timorensis) for the first time. The discrepancy in the morphometric results of the detected trematode eggs with the literature data may suggest the discovery of new helminth species.
KEY WORDS: nematodes, trematodes, Javan rusa, Philippine deer, sambar.
