Urban ponds as a potential risk in the transmission of parasites
We studied freshwater snails inhabiting an urban pond in an enclosed private community from the northern Province of Buenos Aires, Argentina for a year and monitored individuals in order to observe parasite emergence.

Specimens of the predominant snail species were measured and analyzed histologically to examine possible larval effects on the gonadal tissue causing alterations in the developmental stages of the gonads and the degree of parasite prevalence per age, sex, and host size calculated. Four species of snails were registered: Pomacea canaliculata, Physa acuta, Biomphalaria peregrina and Heleobia parchappii. The last of these was the most abundant, whose breeding season was in the spring. The parasitized snails exhibited a greater average length than those free of parasites. The larval prevalence increased with host length, becoming the highest in post-reproductive stage, but was not different between the sexes.

Se estudiaron durante un año los gasterópodos de agua dulce que habitan en un estanque urbano en una comunidad privada cerrada del nordeste de la provincia de Buenos Aires, Argentina. Se monitorearon individuos para observar la emergencia de parásitos. Los especímenes de las especies de caracoles predominantes se midieron y se analizaron histológicamente para examinar los posibles efectos de larvas en el tejido gonadal, provocando alteraciones en las etapas de desarrollo de las gónadas y el grado de prevalencia de parásitos por edad, sexo, y el tamaño del hospedador calculado. Se registraron cuatro especies de gasterópodos: Pomacea canaliculata, Physa acuta, Biomphalaria peregrina y Heleobia parchappii. La última de estas fue más abundante, cuya época de oviposición fue en primavera. Los caracoles parasitados exhibieron una longitud promedio mayor que aquellos libres de parásitos. La prevalencia de larvas aumentó con la longitud del hospedador, llegando a ser la más alta en individuos en etapa postreproductiva, pero no fue diferente entre los sexos. Entre las cercarias emergentes, notamos un marcado predominio de la familia Notocotylidae.
