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,

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,

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 ...

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 ...
