the pond snail lymnaea auricularia serves as an intermediate host for many digenian species. in west azerbaijan province, northwestern iran, the cercariae infection investigation was undertaken in l. auricularia from may to november 2010. of 6759 collected lymnaeid snails, 370(5.5%) l. auricularia snails were identified. cercariae infection was found in a number of 276 (74.56 %) snails. the res...

in the field trials of slow-release nollusicide, copper content mcckechnie chemical inc. 30 cuso4 5h2o or 7.5 cupellet/sinking material 7 days release life were tested against the common aquatic snails bulinus truncatus, physa acuta and lymnaea gedrosiana in stagnant water bodies in khuzestan province, south-west of iran. snail densities before treatment and 7 days after mollucicide application...

two snail species belonging to genus lymnaea, l.auricularia and l.gedrosiana, were collected from 6 different districts of shadegan area of khoozestan. eight percent of the total collections of the snails revealed the occurrence of larva in them. the prevalence of larva within the snails varied in different districts may be due to different geoclimatic conditions and availability of fresh water...

background: fasciolosis in livestock is a crucial concern in the globe, mainly due to its impact on human health. the aim of this study was to determine the rate of infection with fasciola gigantica (cobbold, 1855) larvae in the field-collected snails of lymnaea auricularia (linnaeus, 1785) from northwestern iran using a molecular approach. methods : a total of 6,759 pond snails were collected ...

The ability to correlate the behaviour of neurones in intact ganglia with events in isolation as has been shown in the leech (Ready & Nicholls, 1979; Fuchs, Nicholls & Ready, 1981), may provide insight into the intrinsic properties of individual neurones. The culture of molluscan neurones is relatively new and the exact procedures for the control of environmental conditions necessary for obtain...

The suitability of neurons of the freshwater snail Lymnaea stagnalis as a test system for the neurotoxic side effects of antitumour Vinca alkaloids has been investigated, by studying the process of paracrystal induction by Vinca antitumour agents. Three Vinca alkaloids have been compared: the natural vinblastine and vincristine and the semisynthetic vindesine. They appear to induce two types of...
