This study was conducted to observe the recovery and fecundity of intestinal trematode, Echinostoma revolutum in domestic chick (Gallus gallus domesticus) and notes on their egg development. Each 60 three days old domestic chicks were fed 50 cysts of E. revolutum isolated from Filopaludina martensi martensi. Worm recovery, uterine egg counts, numbers of eggs per gram of feces (EPG), egg morphology and development of E. revolutum during of experimental infection in chicks were analyzed. The worms survived in chicks for 36 days post infection (PI). The incidence of infection was 60.0% (36/60). Of the 1,800 cysts fed to chicks, 465 (27.1%) worms mainly recovered from the jejunum and ileum, occasionally in caeca. The worms became ovigerous by day 10 and produced eggs, which were detected in feces as early as 10 days PI. The number of EPG, determined by a modified formalin-ether concentration technique, as well as EPG per worm increased slowly during day 10-16 PI and then remaining stable and showed a little fluctuation until day 36 PI. Additionally, egg development was characterized from day 0 to 10 post embryonation. Eggs developed fully formed miracidia from chicks after 10 days and emerged later.
