SPATIAL DISTRIBUTION OF LYMNAEIDAE (MOLLUSCA, BASOMMATOPHORA), INTERMEDIATE HOST OF Fasciola hepatica LINNAEUS, 1758 (TREMATODA, DIGENEA) IN BRAZIL

Abstract

Snails of the family Lymnaeidae act as intermediate hosts in the biological cycle of Fasciola hepatica, which is a biological agent of fasciolosis, a parasitic disease of medical importance for humans and animals. The present work aimed to update and map the spatial distribution of the intermediate host snails of F. hepatica in Brazil. Data on the distribution of lymnaeids species were compiled from the Collection of Medical Malacology (Fiocruz-CMM, CPqRR), Collection of Malacology (MZUSP), “SpeciesLink” (CRIA) network and through systematic surveys in the literature. Our maps of the distribution of lymnaeids show that Pseudosuccinea columella is the most common species and it is widespread in the South and Southeast with few records in the Midwest, North and Northeast regions. The distribution of the Galba viatrix, G. cubensis and G. truncatula showed a few records in the South and Southeast regions, they were not reported for the Midwest, North and Northeast. In addition, in the South region there are a few records for G. viatrix and one occurrence of Lymnaea rupestris. Our findings resulted in the first map of the spatial distribution of Lymnaeidae species in Brazil which might be useful to better understand the fasciolosis distribution and delineate priority areas for control interventions.

Snail transmitters of schistosomiasis and other mollusks of medical and economic importance at the Simplício Queda Única Hydroelectric Plant, Southeast Brazil

“…The record of L. columella in the studied area extends this species' distribution to Minas Gerais 11 , increasing the number of inhabited municipalities to 42. We highlight the predominance of the native species P. marmorata over the exotic species P. acuta in the study area because, in the Serra da Mesa Hydroelectric Power Plant reservoir, a population decline occurred in P. marmorata after the introduction of P. acuta 14 .…”

Diversity of Biomphalaria spp. freshwater snails and associated mollusks in areas with schistosomiasis risk, using molecular and spatial analysis tools

“…These ecosystems are home to diverse freshwater mollusk fauna including the genus Biomphalaria; species described in this region are Biomphalaria glabrata (Say 1818), B. tenagophila (d'Orbigny 1835), B. straminea (Dunker 1848), B. occidentalis (Paraense 1981), and B. peregrina (d'Orbigny 1835), as well as Pomacea (Perry 1810), Drepanotrema (Fischer & Crosse 1880), Lymnaea (Lamarck 1799), Melanoides (Olivier 1804), and Physa (Draparnaud 1801).

The population density of Lymnaea columella (Say, 1817) (Mollusca, Lymnaeidae) an intermediate host of Fasciola hepatica (Linnaeus, 1758), in the Caparaó microregion, ES, Brazil

“…Lymnaea columella has a wide geographical distribution, being found in state of Espírito Santo (Medeiros et al, 2014). The structure and abundance of its populations are directly related to the intrinsic interactions of the species and extrinsic properties imposed by the local habitat.…”
