Freshwater snail-borne parasitic diseases in Africa [PDF]

open access: yesTropical Medicine and Health
Background Freshwater snails are the first obligatory intermediate hosts in the trematode life cycle. Several parasitic diseases transmitted by these snails are endemic in Africa, and their distribution closely follows that of the intermediate hosts ...

Range limits and parasite prevalence in a freshwater snail [PDF]

open access: greenProceedings of the Royal Society of London. Series B: Biological Sciences, 2003
Geographical range limits are thought to be set by species' physiological or ecological adaptation to abiotic factors, but the importance of biotic factors such as parasitism in determining range limits has not been well explored. In this study the prevalence of trematode parasitism in populations of a freshwater gastropod snail, Lymnaea stagnalis ...

Draft genome of Semisulcospira libertina, a species of freshwater snail. [PDF]

open access: yesGenomics Inform, 2021
Semisulcospira libertina, a species of freshwater snail, is widespread in East Asia. It is important as a food source. Additionally, it is a vector of clonorchiasis, paragonimiasis, metagonimiasis, and other parasites. Although S. libertina has ecological, commercial, and clinical importance, its whole-genome has not been reported yet.

Responses of four submerged macrophytes to freshwater snail density (Radix swinhoei) under clear‐water conditions: A mesocosm study [PDF]

open access: yesEcology and Evolution, 2020
Macrophytes play a key role in stabilizing clear‐water conditions in shallow freshwater ecosystems. Their populations are maintained by a balance between plant grazing and plant growth.

Opportunity or catastrophe? effect of sea salt on host-parasite survival and reproduction.

open access: yesPLoS Neglected Tropical Diseases, 2022
Seawater intrusion associated with decreasing groundwater levels and rising seawater levels may affect freshwater species and their parasites. While brackish water certainly impacts freshwater systems globally, its impact on disease transmission is ...
