In vitro excystation of Haplorchis taichui (Trematoda: Heterophyidae).
The effects of trypsin, bile extract, temperature and acid-based condition for the in vitro excystation of Haplorchis taichui metacercariae were studied. At 37 degrees C, approximately half the number of metacercariae excysted when exposed to 1% trypsin for 15 minutes with no more excystation found beyond this time. Increasing trypsin concentration seemed to reduce the excystation rate while bi...
متن کاملRecovery and growth of Haplorchis taichui (Trematoda: Heterophyidae) in chicks.
An experimental study was performed to observe the recovery and growth of a minute intestinal fluke, Haplorchis taichui in chicks (Gallus gallus domesticus). Metacercariae of H. taichui were isolated from Jullien's mud carp, Henicorhynchus siamensis, which were collected in the Chiang Mai Province, Thailand. Two hundred metacercariae were orally force-fed to each chick. The intestine of the chi...
متن کاملIn vitro development of Haplorchis taichui (Trematoda: Heterophyidae).
Newly excysted metacercariae of Haplorchis taichui were cultured in a candle jar set at 37 degrees C. Both monophasic culture media [0.85% NaCl, RPMI 1640, RPMI 1640+10% fetal calf serum (FCS)] and diphasic culture media [RPMI 1640 + egg yolk agar, RPMI 1640 + 5%, 10% or 15% blood in blood agar (BA), RMPI 1640 + 5%, 10% and 15% FCS with 5% blood in BA] were used in vitro. Parasites survived for...
متن کاملLight and scanning electron microscopy of Stellantchasmus sp (Trematoda : Heterophyidae).
Light and scanning electron microscopy of heterophyid fluke, Stellantchasmus sp were studied. The adults were obtained from Rattus norvegicus, 7 days after experimental infections with the metacercariae from the body cavity of Dermogenus pusillus. Living specimens and stained flukes were examined by light microscope. The present worm differed from S. batillans having a single testis while teste...
متن کاملDevelopment of Haplorchis taichui (Trematoda: Heterophyidae) in Mus musculus mice.
The development of Haplorchis taichui was studied in sixteen mice, Mus musculus. Metacercarial cysts of H. taichui were obtained from the freshwater fish, Thynnichthys thynnoides, collected in Chiang Mai Province, north Thailand. Approximately 200 active metacercariae were orally introduced into each mouse. Two mice were randomly sacrificed and necropsied daily from day 2-9 postinfection (pi). ...
