“…Similarly as already emphasized by Mas-Coma basing on the data of Brumpt et al (1939Brumpt et al ( -1940, very low infection results (0.6%) and low infection rates (34%) in the same lymnaeid species (L. cousini = L. bogotensis) were also reported in Colombia by Muñoz-Rivas (1953) and more recently noted by Salazar et al (2006), respectively, suggesting that this lymnaeid may not be a good vector. Consequently, the high fascioliasis prevalence in L. cousini snails collected shall be linked to the very high number of cattle living in the farm studied.…”

“…The environmental conditions favouring the development of snail populations and the transmission of the parasite in that Andean area were highlighted to explain such a high transmission rate. The relatively high infection rates of 34.0% and of 39-60% recently obtained in the laboratory with a Colombian isolate of the same lymnaeid species from Vereda la Toibita in Paipa, Boyaca [36], indicate that L. cousini may develop an important transmission role in concrete areas.…”

“…In all these areas, epidemiological and transmission characteristics should a priori fit the valley pattern. Among the lymnaeid species acting as vectors of fascioliasis in these countries, Lymnaea cousini Jousseaume, 1887 is one of the species mainly involved in the transmission in high altitude areas in Ecuador [24,35], Colombia [25,36] and Venezuela [37,38]. Shell morphology, ecological characteristics and seasonal population dynamics of this species [25,39-41] explain why it may be confused, when dealing with young specimens, with other lymnaeids, mainly vector species of the so-called Galba / Fossaria group [42].…”

DNA sequence characterisation and phylogeography of Lymnaea cousini and related species, vectors of fascioliasis in northern Andean countries, with description of L. meridensis n. sp. (Gastropoda: Lymnaeidae)

BackgroundLivestock fascioliasis is a problem throughout Ecuador, Colombia and Venezuela, mainly in Andean areas where the disease also appears to affect humans. Transmission patterns and epidemiological scenarios of liver fluke infection have shown to differ according to the lymnaeid vector snail species involved. These Andean countries present the vectors Lymnaea cousini, L. bogotensis and L. ubaquensis, unknown in the rest of Latin America. An exhaustive combined haplotype study of these species is performed by means of DNA sequencing of the nuclear ribosomal 18S RNA gene, ITS-2 and ITS-1, and mitochondrial DNA cox1 gene.ResultsThe conserved 5.8S rDNA sequence corroborated that no pseudogenes are involved in the numerous non-microsatellite/minisatellite-related indels appearing between the ITS-2 and ITS-1 sequences when comparing different L. cousini - L. bogotensis populations. Sequence analyses and phylogenetic reconstruction methods including other lymnaeid vector species show that (i) L. bogotensis is a synonym of L. cousini, (ii) L. ubaquensis is a synonym of Pseudosuccinea columella, and (iii) populations of L. cousini hitherto known from Venezuelan highlands indeed belong to a new species for which the name L. meridensis n. sp. is proposed. This new species is described and a complete phenotypic differentiation provided.ConclusionsITS-2, ITS-1 and cox1 prove to be good markers for specimen classification and haplotype characterisation of these morphologically similar lymnaeids in endemic areas. Analysis of the 18S gene and phylogenetic reconstructions indicate that L. cousini and L. meridensis n. sp. cluster in an evolutionary line different from the one of P. columella, despite their external resemblance. This suggests an evolutionary phenotypic convergence related to similar environments and which has given rise to frequent specimen misclassification. Body size and phylogenetic relationships of L. meridensis n. sp. with well-known vectors as Lymnaea cousini and P. columella, as well as with Galba/Fossaria species, suggest that the new species may participate in disease transmission to both animals and humans in altitude areas during the yearly window in which temperatures are higher than the F. hepatica minimum development threshold. The involvement of L. cousini and P. columella in the transmission and geographical/altitudinal distribution of fascioliasis in these Andean countries is analysed.

“…Pseudosuccinea columella is a snail of medical interest, since it has been reported as an effective and highly susceptible intermediate host for the zoonotic trematode Fasciola hepatica (Linnaeus, 1758) in different parts of the world (Boray et al 1985;Cruz-Reyes and Malek 1987;Rondelaud and Barthe 1987;Dacal et al 1988;Mas-Coma et al 2009), and being found naturally infected in Australia (Boray et al 1985), Brazil (Ueta 1980;Oliveira et al 2002), Cuba (Gutiérrez et al 2011), Perú (Larrea et al 2007, Colombia (Salazar et al 2006) and Argentina (Prepelitchi et al 2003).…”

Pseudosuccinea columella (Say, 1817) is a lymnaeid snail with great invasive capabilities, and has, at present, a worldwide distribution. So far, the presence of this lymnaeid snail in Argentina was restricted to a few provinces in the northeastern region, such as Misiones, Corrientes, Entre Ríos and some botanical gardens in Buenos Aires, but the recent discovery of specimens in central Argentina (Córdoba) not only represents the first record for the region, but also the southernmost confirmed record in the wild for the Neotropical region and the westernmost for the country.
