Trematode Infection Prevalence Increases With Snail Richness: Observations From a 4-Year Study of Snail-Trematode Interactions. [PDF]

Ecol Evol
We find that higher snail richness correlated with increased overall and generalist trematode infections, while specialist infections showed a similar but nonsignificant trend. The study also highlighted potential host‐switching events and the impact of long‐term sampling on parasite communities, emphasizing the need for continued monitoring of host ...

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 ...

Early Induction of Human Regulatory Dermal Antigen Presenting Cells by Skin-Penetrating Schistosoma Mansoni Cercariae

Frontiers in Immunology, 2018
Following initial invasion of Schistosoma mansoni cercariae, schistosomula reside in the skin for several days during which they can interact with the dermal immune system. While murine experiments have indicated that exposure to radiation-attenuated (RA)

First Record of Trichobilharzia physellae (Talbot, 1936) in Europe, a Possible Causative Agent of Cercarial Dermatitis

Pathogens, 2021
Several species of avian schistosomes are known to cause dermatitis in humans worldwide. In Europe, this applies above all to species of the genus Trichobilharzia.

A Faunistic Survey of Cercariae from Fresh Water Snails: Melanopsis spp. and their Role in Transmission Diseases [PDF]

Iranian Journal of Public Health, 2006
Snail transmitted diseases are one of the major group of helminth parasitic diseases which have been established by trematode parasites. The larvae of trematodes (cercariae) use the snails as host.

The taxonomic survey of the fauna of cercariae (Platyhelminthes, Trematoda) in the mollusks of Uzbekistan

Zoodiversity, 2020
The article provides a list of trematodes cercariae found in the molluscs of Uzbekistan based on the analysis and generalisation of well-known data published in the period between 1934 and 2019. Currently, the list comprises 50 cercaria species belonging

Trematode infection in a freshwater snail Hydrobioides nassa (Gastropoda: Bithyniidae) in Thailand

Helminthologia, 2022
1,024 individuals of Hydrobioides nassa were collected from 12 different localities in eight provinces from north, west, and central regions of Thailand. The infection of parasitic trematodes was investigated using shedding and crushing methods to search

First intermediate hosts of Paragonimus spp. in Vietnam and identification of intramolluscan stages of different Paragonimus species

Parasites & Vectors, 2018
Background Members of the genus Paragonimus require at least three hosts in their life-cycles. The obligatory first intermediate hosts are freshwater snails.

Malacological Survey and Spatial Distribution of Intermediate Host Snails in Schistosomiasis Endemic Districts of Rwanda

Tropical Medicine and Infectious Disease, 2023
Background: Schistosomiasis, due to S. mansoni, is prevalent in Rwanda. However, there is a paucity of information related to the abundance, species, distribution, and infectivity of Schistosoma intermediate host snails.

Identification of Putative Neuropeptides That Alter the Behaviour of Schistosoma mansoni Cercariae

Biology, 2022
Elucidating the infectivity of Schistosoma mansoni, one of the main etiological agents of human schistosomiasis, requires an improved understanding of the behavioural mechanisms of cercariae, the non-feeding mammalian infective stage.
