Estudo morfométrico da concha de Lymnaea columella say, 1817 (Mollusca, Gastropoda, Pulmonata)

Abstract: Foram estudadas variações morfométricas de conchas de L. columella, provenientes de dez criadouros localizados nos seguintes municípios do Estado de São Paulo: -Campinas, Americana, Atibaia, Pirassununga, Caçapava e Taubaté.Foram analisados os diferentes tipos de ambientes onde as limneas são encontradas com maior freqüência, estabelecendo-se a época do ano com maior abundância em espécimes, que correspondeu aos meses de julho a outubro.As medidas nas conhas dos diferentes criadouros referiram-se ao compriment… Show more

“…Contrary to F. cubensis, where egg-laying cease before the onset of the cercaria-shedding period in infected snails (Gutiérrez et al 2001), P. columella can lay eggs even while shedding cercaria (Gutiérrez et al 2002). In addition, P. columella has been found naturally infected in Brazil and Australia (Ueta 1980, Boray et al 1985, Oliveira et al 2002 and its invasive nature has been observed in places like the island of Guadeloupe (Jean P Pointier, pers. commun.).…”

“…However, in Brazil, there are no reports of natural infection by other non-lymnaeid snails. Morphologically, lymnaeid are characterized by having an elongated conical shell, with convex turns, shallow or deep sutures, turns to the right (dextrogyra) and with an opening tending to be elongated-oval or rounded-ovoid, which can occupy half or even three-fourths the total shell length (Ueta, 1980) (Figure 1). The species Pseudosuccinea columella, previously known in the literature as Lymnaea columella, is currently considered the main intermediate host of F. hepatica in Brazil (Bánki et al, 2024).…”

“…In the Caribbean area P. columella was reported from Puerto Rico (Van der Schalie, 1948), Dominican Republic (Gómez et al , 1986), Venezuela (Malek & Chrosciechowski, 1964) and Guadeloupe (Pointier, 2008) but was never recorded as an active intermediate host of F. hepatica in the field. However, as already pointed out, in several other invaded countries, such as Australia, Brazil and Argentina, P. columella has been reported to be naturally infected by F. hepatica (Ueta, 1980; Boray et al , 1985; Prepelitchi et al , 2003). Consequently, the discovery of naturally infected P. columella in Cuba shows that this species must be seriously taken into account in the development of future control programmes of this parasitosis.…”

“…In Cuba, only two lymnaeid species occur, Fossaria cubensis and Pseudosuccinea columella , but until now the former had been the only species found to be naturally infected in the field by the parasite (Melcon & Perera, 1994; Gutiérrez et al , 2003a, 2005a, b). Although no report on P. columella harbouring parasite larvae under natural conditions had previously been made for the Caribbean area, this snail is also considered an effective host of F. hepatica as it acts as a natural intermediate host in countries such as Brazil, Australia and Argentina (Ueta, 1980; Boray et al , 1985; Oliveira et al , 2002; Prepelitchi et al , 2003) and it shows a high susceptibility to miracidial exposures under laboratory conditions (Léon-Dancel, 1970; Boray et al , 1985; Gutiérrez et al , 2002).…”
