Microsatellite variation in the freshwater snail Physa acuta
Molecular Ecology Notes, 2002AbstractWe present data for seven new markers isolated from a microsatellite‐enriched DNA library from the freshwater snail Physa acuta. Six of them appear to be conserved in Physa cubensis. These loci might be useful for analysing population structure and reconstructing the story of invasion of freshwaters on a worldwide scale by P. acuta.

Utilização do gastrópode aquático Physa acuta em ensaios in situ
Revista Captar: Ciência e Ambiente para Todos, 2019Os ensaios in situ constituem uma ferramenta efetiva e ambientalmente relevante de avaliação de efeitos ecotoxicológicos, permitindo estabelecer relações causa-efeito em ambientes aquáticos sujeitos a vários agentes de stress. Entre as várias espécies aquáticas utilizadas neste tipo de testes, o gastrópode Physa acuta assume-se como um potencial ...

Three morphogenetic waves in early development of Physa acuta (gastropoda, pulmonata)
Cell Biology International Reports, 1985Evidence is presented that there are three morphogenetic waves in early development of Physa acuta: a) around 24-cell stage, b) at early gastrula, and c) at early trochophore, using a proflavin biological test. These morphogenetic maxima fit very well with three transcriptional maxima.

Multiple unfolding states of glutathione transferase from Physa acuta (Gastropada: Physidae)
Biochemical and Biophysical Research Communications, 2006The equilibrium unfolding of the major Physa acuta glutathione transferase isoenzyme (P. acuta GST(3)) has been performed using guanidinium chloride (GdmCl), urea, and acid denaturation to investigate the unfolding intermediates. Protein transitions were monitored by intrinsic fluorescence. The results indicate that unfolding of P.

Identification and characterization of a goose-type lysozyme from sewage snail Physa acuta
Fish & Shellfish Immunology, 2014Freshwater snail Physa acuta has been considered as an important invasive species and medical mollusc. Field investigation has shown that this snail could survive better than other snails in polluted water bodies. To understand the immune mechanisms of P. acuta, suppression subtractive hybridization hepatopancreas cDNA library has been constructed with

Effects of different ionic compositions on survival and growth of Physa acuta
Aquatic Ecology, 2007Most inland saline waters in southern Australia predominantly contain Na+ and Cl− as major ions. The proportions of Ca2+, Mg2+, SO4 2−, HCO3 − and CO3 2− in these waters somewhat vary and might influence salinity tolerance of freshwater organisms.

Abstract. It has long been speculated that Physa acuta, a pulmonate snail widespread and invasive in fresh waters of the old world, may have originated in North America. But the identification of a new‐world cognate has been complicated by the confused systematics and taxonomy of the Physidae in America.
