Current decline in the number and size of Galba truncatula and Omphiscola glabra populations, intermediate hosts of Fasciola hepatica, on the acidic soils of Central France [PDF]

open access: yesParasite, 2016
Field investigations on the habitats colonized by Galba truncatula or Omphiscola glabra were carried out on 162 farms of the Limousin region, Central France, to determine whether there is currently a decline in the number and size of snail populations ...

Changes in the Populations of Two Lymnaeidae and Their Infection by Fasciola hepatica and/or Calicophoron daubneyi over the Past 30 Years in Central France [PDF]

open access: yesAnimals, 2022
Field investigations were carried out during three periods (from 1976 to 1997, in 2013–2014, and in 2020–2021) on 39 cattle-raising farms on acidic soils to track changes in the populations of two Lymnaeidae (Galba truncatula and Omphiscola glabra) and ...

Molecular characterisation of Galba truncatula, Lymnaea neotropica and L. schirazensis from Cajamarca, Peru and their potential role in transmission of human and animal fascioliasis [PDF]

open access: yesParasites & Vectors, 2012
Background Human and animal fascioliasis is emerging in many world regions, among which Andean countries constitute the largest regional hot spot and Peru the country presenting more human endemic areas.

Galba truncatula: Distribution, Presence in Fountains and Identification of Factors Related to Its Occurrence in Bulgaria [PDF]

open access: yesAnimals
Galba truncatula acts as an intermediate host for several parasitic flukes of veterinary importance, but a targeted study on its spatial presence as well as the impact of environmental factors in Southeastern Europe has not been conducted.

Longitudinal study on the temporal and micro-spatial distribution of Galba truncatula in four farms in Belgium as a base for small-scale risk mapping of Fasciola hepatica [PDF]

open access: yesParasites & Vectors, 2014
Background The trematode parasite Fasciola hepatica causes important economic losses in ruminants worldwide. Current spatial distribution models do not provide sufficient detail to support farm-specific control strategies. A technology to reliably assess

Clonal amplification of Fasciola hepatica in Galba truncatula: within and between isolate variation of triclabendazole-susceptible and -resistant clones [PDF]

open access: yesParasites & Vectors, 2018
Background Fasciola hepatica is of worldwide significance, impacting on the health, welfare and productivity of livestock and regarded by WHO as a re-emerging zoonosis.

Environmental influences on the distribution and ecology of the fluke intermediate host Galba truncatula: a systematic review [PDF]

open access: yesParasitology
Galba truncatula is one of the most distributed intermediate hosts of Fasciola hepatica across Europe, North Africa and South America. Therefore, understanding the environmental preferences of this species is vital for developing control strategies for ...

Haplometra cylindracea (Zeder, 1800) (Trematoda: Plagiorchiidae): variation in the dates of cercarial shedding for overwintering Galba truncatula [PDF]

open access: yesParasite, 2011
Natural infections of Galba truncatula with Haplometra cylindracea were followed from 2001 to 2009 to determine if their characteristics were similar when snails came from water collections frequented by Bufo bufo or by frogs and newts for their egg ...

Fasciola hepatica: effect of the natural light level on cercarial emergence from temperature-challenged Galba truncatula [PDF]

open access: yesParasite, 2014
As abrupt changes in water temperature (thermal shock) triggered a significantly greater cercarial emergence of Fasciola hepatica from experimentally infected Galba truncatula, laboratory investigations were carried out to study the influence of light on

The prevalence and infection rates of amphistome species in intermediate snail hosts: a systematic review and meta-analysis [PDF]

open access: yesFrontiers in Veterinary Science
The systematic review and meta-analysis were conducted to determine the estimates of the prevalence and infection rates of natural and experimental infections of amphistome species in intermediate host snails (IHs) across different continents.
