Genomic analysis of a parasite invasion: Colonization of the Americas by the blood fluke Schistosoma mansoni

Molecular Ecology, Volume 31, Issue 8, Page 2242-2263, April 2022., 2022
Abstract Schistosoma mansoni, a snail‐borne, blood fluke that infects humans, was introduced into the Americas from Africa during the Trans‐Atlantic slave trade. As this parasite shows strong specificity to the snail intermediate host, we expected that adaptation to South American Biomphalaria spp.

Cercarial production from Biomphalaria alexandrina infected with Schistosoma mansoni. [PDF]

Bulletin of the World Health Organization, 1970
The present paper deals with longitudinal and cross-sectional methods of counting cercariae shed from Biomphalaria alexandrina in Egypt, both experimentally and naturally infected with schistosomes. By the longitudinal method, the daily output of cercariae was counted from the first shedding from experimentally infected snails and from the day of ...

INFECTED FRESHWATER SNAILS, BIOMPHALARIA ALEXANDRINA, THE INTERMEDIATE HOST OF SCHISTOSOMA MANSONI [PDF]

Journal of the Egyptian Society of Parasitology, 2018
The objective was to study the chromosomes of Biomphalaria alexandrina snails (class Gastropoda) in control and infected state which could be helpful in understanding how host-parasite relationships in feasible and effective control measures.

The effect of mating on female reproduction across hermaphroditic freshwater snails

Invertebrate Biology, Volume 139, Issue 1, March 2020., 2020
Abstract Sexual conflicts often arise between mating partners because each sex tries to maximize its own reproductive success. One major male strategy to influence a partner's resource allocation is the transfer of accessory gland proteins. This has been shown to occur in simultaneous hermaphrodites as well as in organisms with separate sexes. Although

Prevalence of Schistosoma mansoni and S. haematobium in Snail Intermediate Hosts in Africa: A Systematic Review and Meta‐analysis

Journal of Tropical Medicine, Volume 2020, Issue 1, 2020., 2020
Background. Schistosomiasis is caused by Schistosoma mansoni and S. haematobium in Africa. These schistosome parasites use freshwater snail intermediate hosts to complete their lifecycle. Varied prevalence rates of these parasites in the snail intermediate hosts were reported from several African countries, but there were no summarized data for ...
