The proteomic analysis was performed at the proteomics facility of SCSIE, University of Valencia (Burjassot, Spain) that belongs to ProteoRed, PRB2-ISCIII, Madrid, Spain. We also thank Dr. Tatiana Corey, Dr. Amy Beierschmitt and Dr. Pompei Bolfa for their support during sample collection.
Echinostomes in the definitive host: a model for the study of host-parasite relationships.
2008
Echinostomes are hermaphroditic digeneans that parasitize, as adults, numerous vertebrate hosts of all classes. In this chapter, the main features of the development of adult echinostome in the definitive host are analyzed in detail. The stage of the echinostome in the definitive host undergoes a number of features such as metacercarial excystment, establishment, habitat location, adult development, mate, and release of eggs. These features are documented with an emphasis in their potential use as experimental models. The analysis is focused on members of the genus Echinostoma, although members of other genera of the Echinostomatidae are mentioned when they are relevant to the discussion. A…
Immunology and pathology of echinostome infections in the definitive host.
2008
This chapter examines the salient literature on the immunology and pathology of members of the family Echinostomatidae in their definitive hosts, with emphasis on experimental studies that may provide useful information on factors that determine resistance to the parasites. For this purpose, several topics such as manifestations and mechanisms of resistance to infection, experimental strategies, and antigenic characterization of echinostomes are covered. Moreover, other topics such as immunodiagnosis are also analyzed. The analysis is focused on members of the genus Echinostoma. Although some of the nomenclature for echinostome species is disputed, the names used are those currently accepte…
The influence of adult worm age and definitive host on the transmission of Echinostoma caproni: egg hatchability and miracidial infectivity.
2012
AbstractWe analysed the influence of different ages of Echinostoma caproni adult worms reared in different definitive host-species on egg hatchability and miracidial infectivity. Eggs obtained from 2-, 4- and 6-week-old adult worms collected from rats, hamsters and mice, hatched miracidia that were used to infect laboratory-reared specimens of Biomphalaria glabrata. Highest egg hatchability was obtained with eggs derived from hamsters and mice. Egg hatchability did not seem to be affected by the age of E. caproni adult worms. Miracidial infectivity was not affected by the definitive host species. However, miracidial infectivity was affected by the age of adult worms when they developed in t…
