Physiological alterations in Pseudosuccinea columella (Mollusca: Gastropoda) after infection by Heterorhabditis baujardi LPP7 (Rhabditida: Heterorhabditidae).

The snail Pseudosuccinea columella participates in the distribution of Fasciola hepatica in the environment by acting as its intermediate host. Therefore, the control of this lymnaeid is one of the ways to prevent hepatic fascioliasis. The objective of this study was to evaluate the susceptibility of P.

Association of radioactivity of the monazite sands of the beaches of the Guarapari city with the presence of parasites of zoonotic potential.

The city of Guarapari, known as "Healthy City", has as its main tourist attraction radioactive sands known as monazite sands. There are many studies aimed at quantifying radiation, but little is known about an influence of radiation levels on the life cycle of parasites with zoonotic potential, since many owners take their animals to beaches facilitating a maintenance of their cycle. The objective of the present work was to evaluate the association of the sand radiation of the beaches of the municipality of Guarapari and the presence of eggs and larvae of zoonotic potential parasites.
