Observations on Some Heterophyidae (Trematoda: Digenea) Encysted in Philippine Fishes

Larval stages of medically important flukes (Trematoda) from Vientiane province, Laos.

“…However, the fish of the genus Ham pala have not been referred to as a host of H. taichui metacercariae. H. pumilio metacercariae has hitherto been recorded in fish from Africa (Kenya, Egypt) and several Asian coun tries, e. g. Israel, India, China, Taiwan, Philippines (Hsü, 1950;Pearson, 1964;Pande and Shukla, 1972;Velasquez, 1973;Khalifa et al, 1977 ;Sommerville, 1982 a, b). However, we did not succeed in finding any data on the occurrence of H. pumilio metacercariae from countries of the past Indochina (Vietnam, Cambodia, Laos).…”

“…Localities: Nam Ngum water reservoir (2 localities), river Mekong in Vientiane. Comments: H. taichui metacercariae have been recorded in fish from any Asian countries, e. g., Israel, India, China, Taiwan, Philippines (Hsü, 1950;Pearson, 1964;Nath and Pande, 1970;Velasquez, 1973). In Thailand, H. taichui larvae were found in Puntius ( = Barbodes) gonionotus, Puntius leiacanthus ( = brevis) and P. orphoides (Kliks and Tantachamrun, 1974).…”

Epidemiological Survey on the Infection of Intestinal Flukes in Residents of Muan-gun, Jeollanam-do, the Republic of Korea

“…Therefore, it was confirmed for the first time that this fluke is a human-infecting species by the present study. In case of the other species of Acanthotrema, A. tanayensis and A. tridactyla were recovered from cats, A. cursitans from rodents, and A. martini, A. acanthotrema, A. armata, A. tridactyla and A. hancocki were found from avian hosts [18][19][20][21].…”

Identification of Acanthotrema felis (Digenea: Heterophyidae) metacercariae encysted in the brackish water fish Acanthogobius flavimanus

“…Kittens have been shown to be the experimental definitive host not only for A. felis but also for A. tanayensis (Velasquez, 1973) and A. tridactyla (Abdul-Salam et al, 2000). Other mammals, including laboratory rodents, were reported to be the natural and experimental definitive hosts for A. cursitans (Kinsella and Heard, 1974).…”

“…The second intermediate hosts of the species of Acanthotrema have been reported to be the brackish water fishes; Gillichthys mirabilis and Fundulus parvipinnis for A. hancocki (Martin, 1950), Aphanius fasciatus for A. tridactyla (Martin and Kuntz, 1955), Ophiocara aporos for A. tanayensis (Velasquez, 1973) and Fundulus confluentis, F. similis and F. grandis for A. cursitans (Kinsella and Heard, 1974). Additionally, in the case of A. felis, a species of the brackish water fish, A. flavimanus, has been confirmed to act as a second intermediate host.…”
