Ultrastructure and chaetotaxy of sensory eeceptors in the cercaria of a species of Allopodocotyle Pritchard, 1966 (Digenea: Opecoelidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 2001
Previous investigations of sensory systems in opecoelid cercariae have focused on chaetotaxy and ultrastructure of sensory receptors. They revealed chaetotaxic patterns within family, genus, and species as well as different receptors.

Local adaptation of the trematode Fasciola hepatica to the snail Galba truncatula

open access: yesParasite, 2012
Experimental infections of six riverbank populations of Galba truncatula with Fasciola hepatica were carried out to determine if the poor susceptibility of these populations to this digenean might be due to the scarcity or the absence of natural ...

Trematode Fluke Procerovum varium as Cause of Ocular Inflammation in Children, South India

open access: yesEmerging Infectious Diseases, 2016
Trematodes are recognized as a group of emerging parasites in tropical countries. We identified a trematode as a cause of ocular granulomas that developed in children who bathed in ponds or rivers in South India.

The redial and cercarial production of a Digenean in the snail host is lower when no cercarial shedding occurs

open access: yesParasite, 2009
Single- and double-miracidium exposures of Galba truncatula with Fasciola hepatica (two groups) or with Paramphistomum daubneyi (two groups) were carried out under laboratory conditions to compare parasite production in cercaria-shedding snails (CS ...

Haplometra cylindracea (Zeder, 1800) (Trematoda: Plagiorchiidae): variation in the dates of cercarial shedding for overwintering Galba truncatula

open access: yesParasite, 2011
Natural infections of Galba truncatula with Haplometra cylindracea were followed from 2001 to 2009 to determine if their characteristics were similar when snails came from water collections frequented by Bufo bufo or by frogs and newts for their egg ...

Kinetics of the cercaria-schistosomul um transformation in vivo: 2. The effect of oxamniquine

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 1985
To study the cercaria-schistosomulum transformation in vivo, underthe influence of an antischistosomal compound (oxamniquine), a model using cercarial infections into the abdominal cavity of mice was chosen.
