this guide to the identification of iranian freshwater snails has been prepared with aim of helping individuals involved in field work, but who have had no specialized training in taxonomy to differentiate snail specimens which they collect to certain groups by means of simple identification key. the guide pays special attention to the principal snail groups which transmit human schistosomiasis...

studies undertaken on the susceptibility of various local snails to some of the important human and animal trematodes found in iran have revealed that bulinus truncatus, the distribution of which is restricted to the province of khuzestan in the southwest of iran is the intermediate host of shistosoma haematobium, s. bovis and paramaphistomum microbothrium in this area.this snail is also suscep...

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 re...

there are many freshwater snails involved in the life cycle of parasitic flukes. some of these animals, such as bulinus spp and lymnaea spp are very important in public health and veterinary medicine. for example, bulinus trucatus and lymnaeid snails transmit human bilharziosis and zoonotic fascioliosis, respectively. for this reason most freshwater bodies of northern iran, were searched for po...

BACKGROUND The construction and operation of small multipurpose dams in Africa have a history of altering the transmission of water-based diseases, including schistosomiasis. The current study was designed to investigate the abundance and dynamics of schistosomiasis intermediate host snails and Schistosoma infections in humans during the construction and the first years of operation of a small ...

Schistosomiasis is an important parasitic disease, touching roughly 200 million people worldwide. The causative agents are different Schistosoma species. Schistosomes have a complex life cycle, with a freshwater snail as intermediate host. After infection, sporocysts develop inside the snail host and give rise to human dwelling larvae. We present here a detailed step-by-step video instruction i...

The rapidly increasing number of spatial studies and the complexity of schistosomiasis transmission dynamics in Brazil indicate that surveillance and control programmes can benefit from the spatial approach, not only in areas susceptible to the introduction and establishment of new transmission foci but also in areas experiencing declines in schistosomiasis transmission. Several additional area...
