Effects of Physicochemical Factors on Loss of Infectivity of Opisthorchis viverrini Cercariae

Walailak Journal of Science and Technology, 2021
This study aims to develop an alternative field-based approach to interrupt the life cycle of O. viverrini. The effects of temperature, salinity, acidity, ultraviolet A, B, C radiation, and combinations of these physicochemical factors on the loss of ...

Trematode cercarial fauna obtained from the field-collected freshwater snails Lymnaea natalensis in Egypt

Bulletin of the National Research Centre, 2019
Background Lymnaea natalensis is the snail intermediate host for Fasciola spp. parasites. The purpose of the present investigation is to detect the different trematodes’ larval stages in this snail from three rural localities in Giza Governorate ...

Trematodes obtained from the thiarid freshwater snail Melanoides tuberculata (Müller, 1774) as vector of human infections in Thailand

Zoosystematics and Evolution, 2014
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.

THE DEVASTING EFFECTS OF PRAZIQUANTEL AND ALBENDAZOLE, ON CERCARIAE OFTHEDIGENEANPHANEROPSOLUS PRAOMIDIS (BAER, 1971) [PDF]

Journal of the Egyptian Society of Parasitology
Phaneropsolidae is one of the digenean intestinal parasites of reptiles, birds, and mammals. To cease its life cycle, some cercariacidal drugs were used, such as praziquantel and albendazole. The intermediate host, a freshwater snail, Lanistes carinatus,

Effects of Land-Use and Environmental Factors on Snail Distribution and Trematode Infection in Ethiopia

Tropical Medicine and Infectious Disease, 2023
Freshwater snails are intermediate hosts for several snail-borne diseases affecting humans and animals. Understanding the distribution of snail intermediate hosts and their infection status is very important to plan and implement effective disease ...

Environmental determinants of distribution of freshwater snails and trematode infection in the Omo Gibe River Basin, southwest Ethiopia

Infectious Diseases of Poverty, 2019
Background Determination of infection rates of snail populations is one of the basic tools for epidemiological studies of snail borne diseases. In this study, we opted to determine the trematode infection of freshwater snails in the Omo-Gibe River Basin,

Exploring the evolutionary potential of parasites: Larval stages of pathogen digenic trematodes in their thiarid snail host Tarebia granifera in Thailand

Zoosystematics and Evolution, 2018
Minute intestinal flukes from several distinct families of endoparasitic platyhelminths are a medically important group of foodborne trematodes prevalent throughout Southeast Asia and Australasia.

Cercariae of a Bird Schistosome Follow a Similar Emergence Pattern under Different Subarctic Conditions: First Experimental Study

Pathogens, 2022
The emergence of cercariae from infected mollusks is considered one of the most important adaptive strategies for maintaining the trematode life cycle. Short transmission opportunities of cercariae are often compensated by periodic daily rhythms in the ...

Trematode infections in frogs: Do all cercarial morphotypes infect and induce effects on the common hourglass tree frog, Polypedates cruciger?

Ceylon Journal of Science, 2018
Trematode infections are known to induce malformations and increase mortality in amphibians. However, not all the larval trematodes induce effects on the host. Nine types of cercariae (A-I) belonging to five morphotypes (oculopleurolophocercous, distome,

Adhesion of Cercaria (Larva of Helminth Parasites) to Host by Lectins- carbohydrates bonds as a Model for Evaluation of Schistosoma Entrance Mechanisms in Cercarial Dermatitis [PDF]

Iranian Journal of Public Health, 2008
Background: Cercariae (larva of helminth parasites) are covered by a thick glycocalyx coat, which serves as an osmotic pro­tection during their free existence, and contain carbohydrates conjugated as glycoproteins, glycolipids and mu­co­polysaccharides ...
