“…Ciliated and non-ciliated dome-shaped papillae have also been described in other adult trematode worms (see Chai et al, 1998Chai et al, , 2000Woo et al, 1998;Abdul-Salam et al, 2000;Dangprasert et al, 2001). The dome-shaped ciliated papillae of B. cribbi adult worms appear similar to those described in other trematodes except that the cilium is rarely seen extended from the stoma.…”

Brachylaima cribbi is a recently described species of terrestrial trematode that infects mammals and birds with helicid land snails as its first and second intermediate hosts. The adult worm is 2.5-6.0 mm long by 0.5-0.8 mm wide being a long slender cylindrical worm with oral and ventral suckers in the anterior quarter and genital pore in the posterior quarter. Scanning electron microscopy shows that there is a dense covering of tegumental spines at the anterior end which diminishes towards the posterior extremities of the worm. Development of spines was observed in juvenile and mature adult worms. In young worms 1-3 weeks post infection (wpi) spines appear as buds with a serrated edge each having 1-4 spikes per spine. As the worm ages the spines broaden and by 5 wpi the number of spikes per spine increases to an average of 8.1. The serial development of oral sucker papillae in the cercaria, metacercaria and adult worm was observed with the finding of an elongated papilla with a bifurcated tip on the cercaria becoming a shorter and thicker elongated papilla with a large central stoma on the metacercaria. In the adult worm, this papilla becomes dome-shaped with a small central stoma. For some of these papillae a cilium could be seen extended from the central stoma. Other life-cycle stages illustrated were the hatched egg with an extruded egg membrane minus an operculum and a portion of the branched sporocyst dissected from the digestive gland of the land snail Theba pisana showing a terminal birth pore. Scanning electron microscopy morphological features of the adult worm observed for the first time in a Brachylaima were the unarmed cirrus extended from the genital pore with released sperm present and the Laurer's canal opening visible in tegumental folds on the dorsal surface approximately 300 microm posterior to the genital pore.

“…One of heterophyid trematodes, Stictodora tridactyla was reported that they occasionally infested brackish water and marine snails, while metacercariae encyst in fish, with the definitive hosts being birds and mammals including humans (Chai et al 1988, Abdul-Salam et al 2000. S. tridactyla also infected M. tuberculata with other cercariae as well.…”

Larval stages of trematodes obtained from the freshwater snail Melanoides tuberculata (Cerithioidea, Thiaridae) as intermediate host were studied by using cercarial emergence and crushing snails. Between December 2004 and September 2009 snails from one hundred twenty locations in Thailand were collected every two months for one year at each sampling site. Counts per unit of time method was used in this study, and the samples of snails were collected every 10 minutes per sampling by five collectors. The cercarial stages were examined using shedding and crushing methods. The infection rate was found to be 18.79%, i.e. 6,019 animals infected in a total of 32,026. Nine different types in eighteen species of cercariae were categorized, viz. are (1) Parapleurophocercous

“…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).…”
