BACKGROUND The present study was carried out to detect the infection of larval stages of Trichobilharzia species in the snail Lymnaea auricularia in northwestern Iran based on DNA analysis. METHODS A total number of 320 snails of L. auricularia were sampled from four water-bodies located in the suburb of Urmia City, North West Iran, during May to November 2011. The snails were first microscop...

The ram's horn snail (Planorbella trivolvis (Say)) is an intermediate host for a digenetic trematode (Bolbophorus confusus (Krause) Dubois) that has recently been discovered to be a significant problem in commercial channel catfish (Ictalurus punctatus Raf) production ponds in the Mississippi Delta region in the USA. In these catfish ponds, the digenetic life cycle of this parasitic trematode i...

Bulinus truncatus snail is the intermediate host of Schistosoma haematobium, which causes serious damage to urinary system infected patients. To control it in its rapid interruption and/or elimination disease transmission would be efficient. Copper chlorophyllin (Cu-chl) and magnesium (Mg-chl); two photosensitizers used several biological applications, were bio-assayed against B. snails.  Mg-ch...

After infection with the digenetic trematode Echinostoma paraensei, hemolymph of the snail Biomphalaria glabrata contains lectins comprised of 65-kDa subunits that precipitate polypeptides secreted by E. paraensei intramolluscan larvae. Comparable activity is lacking in hemolymph of uninfected snails. Three different cDNAs with sequence similarities to peptides derived from the 65-kDa lectins w...

The rate of ingestion of Fasciola normal metacercariae (NMc) encysted on plants by Lymnaea ollula was examined, and the infectivity of the ingested metacercariae (IMc) in the feces of the host snail to mice was studied. As a result of ingestion by snails, the metacercarial outer cyst disappeared in about 50% of IMc in feces. There was no significant difference in the liver juvenile recovery at ...

Schistosoma mansoni is an important human parasitic disease which is widespread throughout Africa. As Biomphalaria pfeifferi snails act as intermediate host, knowledge of their population ecology is an essential prerequisite towards understanding disease transmission. We conducted a field study and assessed the density and microhabitat preferences of B.pfeifferi in a natural habitat which was a...

BACKGROUND The last study on snail population density in relation to rainfall pattern in Kigungu canoe landing and recreational sites on Lake Victoria shore was earlier carried out about fifteen years ago. This study also reviewed the influence of other environmental factors on the snails' infection rate. OBJECTIVE To reassess the density dynamic of Biomphalaria (B) choanomphala and Biomphala...

background: hadjelia truncata is a nematode that causes lesions in the gizzard lining of pigeons, which may even lead to death. the aim of this study was to introduce alphitobius diaperinus as a new intermediate host for hadjelia truncata . methods: h. truncata infection was identified in a pigeon flock in ahvaz city, khuzestan province, iran by performing fecal examination and autopsy. adult a...

Gastrodiscosis outbreaks due to Gastrodiscus aegyptiacus were recorded in horses in the vicinity of Harare, Zimbabwe, in the absence of Bulinus forskalii, B. senegalensis and Cleopatra sp. which are considered to be the only intermediate host snails. This suggested the possibility of other snail species acting as intermediate hosts in the life cycle of the trematode. A study was carried out to ...
