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 ...

Characterization, cloning and immunogenicity of antigens released by lung-stage larvae of Schistosoma mansoni [PDF]

, 1999
Lung-stage schistosomula are the target of protective immunity in mice vaccinated with attenuated cercariae of Schistosoma mansoni. Therefore, proteins present at this developmental stage, and in particular those which are secreted, are a potential ...

Signaling via interleukin-4, receptor alpha chain is required for successful vaccination against schistosomiasis in BALB/c mice [PDF]

, 2001
Radiation-attenuated (RA) schistosome larvae are potent stimulators of innate immune responses at the skin site of exposure (pinna) that are likely to be important factors in the development of Th1-mediated protective immunity.

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 ...

Cercariae (Digenea: Strigeidae, Diplostomidae) in Biomphalaria straminea (Planorbidae) from a rice field in Northeastern Argentina [PDF]

, 2017
The rice fields can provide habitats for many species of aquatic invertebrates, as insects, molluscs, crustaceans; and vertebrates, as fish, amphibians, reptiles and birds, which may act as hosts in the life cycles of digenean parasites. In this context,
