field trials of molluscicide wl8008 (n-tritylmorpholine) were carried out in khuzestan, iran. the liquid 2 (fx/28), a 16.5 w/v emulsifiable concentrate in tetrachloroethylene in concentrations of 0.25 ppm and 0.5 ppm was used against bulinus truncatus and lymnaea gedrosiana in standing and running water systems . bio-assay tests and laboratory experiments were made parallel to the field trials....

the laboratory infection of lymnaea gedrosiana with 2,5 and 10 miracidia of fasciola gigantica resulted in infection rates of 20%, 40% and 69%, respectively, with a prepatent period of 66-88 days. there was a significant difference in infection rate between the snails infected with 2 and those with 10 miracidia (p<0.05). at 92 days post- infection there was 25% to 33.3% of live snails still har...

many species of the freshwater pulmonate snail family lymnaeidae act as intermediate hosts in the transmission of digenean trematode larvae, including those of the causative agent of fasciolosis. based on this, current investigation was aimed to determine diversity and geographical distribution of lymnaeidae snails and role of biochemical indices in habitat of them in west azerbaijan province, ...

background: in this study the haemolymph components of infected and none infected lymnaea gedrosiana with xiphidiocercaria larvae was compared. methods: five hundred fifty lymnaea snails were collected from ilam and mazandaran prov­inces, iran, during 2008-2009. the snails were transported to the lab at tehran university of medi­cal sciences and their cercarial sheddings were studied. haemolmyp...

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...

BACKGROUND The study concerns the prevalence of avian schistosomes in intermediate and definite hosts in Mazandaran Province, northern Iran. METHODS A total of 14190 fresh-water snails belonging to various genera were sampled and tested for cercarial emission by lighting and then crushing. During the same period, the nasal blood vessels and mesenteric veins of aquatic birds, mainly belonging ...

ornithobilharziosis, as one of the parasitic infections, may give rise to serious economic problems in animal husbandry.the objective of the present study was determining prevalence of ornithobilharzia turkestanium in sheep in the mazandaran province and identify snails which could be responsible for transmission of infection animals from 2005 to 2010. a total of 900 faecal from 900 sheep herds...

trematodes are important in economic and public health. ornithobilharzia turkestanicum (o. turkestanicum) is one of the important economic trematodes in domestic animals. ornithobilharzia infection in intermediate host (lymnaea gedrosiana ) can be detected by either exposing snails to light to induce cercarial shedding or by squeezing them between glass slides to detect parasites. the current a...

Snails are creatures present in various ecosystems that, in addition to being present in human surroundings, some of them are also important in veterinary medicine and medicine as the intermediate hosts of Digenean trematodes. The present study was conducted to identify and determine the geographical distribution of freshwater snails and investigate the relationship of variables, such as season...

BACKGROUND Cercarial dermatitis' or swimmer's itch' is an itchy inflammatory response to the penetration of the skin by non-human schistosome parasites. In the hot season, (May to September) in Khuzestan province in the south west of Iran, swimming in canals and agriculture activities in swampy areas are common. This survey was made on people from villages north of Ahwaz city in south west Iran...
