The hot-spots of transmission food-borne zoonotic trematodes in northern Vietnam have been known as the integrated fish-livestock (VAC- Garden, Fish pond, Poultry shed) ponds. A cross-sectional study was conducted Ha Noi capital and Yen Bai province to investigate trematode larval infections (cercariae) freshwater snails these areas. Snails were collected from 35 VAC ponds, including 25 grow-ou...

The 5’ end of the small subunit ribosomal RNA gene was used to determine whether 3rd larval stage Angiostrongylus cantonensis are present in populations of the giant African land snail Achatina fulica from French Polynesia. Two populations, one from Moaroa Valley, Tahiti (n=5) and the other from Haapiti Valley, Moorea (n=10), were examined. All snails from Tahiti were infected with nematodes, w...

Objective: An experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  Methods: One hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. Each replicate contains 15 chicks. The t...

the biology of immature stages of s.sphegea and different techniques for their laboratory rearing has been studied during the past five years (1972-77). this fly is one of the 18 iranian species of snail-killing flies which is dominant in the focus area of schistosomiasis (khuzestan province) in the south-west of iran. the following procedures improved appreciably our laboratory rearin-technics...

Mosquito-borne diseases are a consistent problem in Vietnam. Additionally, freshwater snail species agricultural pests and known to be intermediate hosts for several parasitic worms. There is need new complementary botanical pesticidal agents controlling these essential oils have shown promise. In this work, from 2 of Callicarpa ( C. rubella sinuata) 4 Premna P. chevalieri, corymbosa, maclurei,...

Use of molluscicides in the attractant food pellet (AFP) is an effective method of snail control. Different concentrations of these molluscicides viz. Azadirachta indica bark powder, Allium sativum bulb powder, Polianthes tuberosa bulb powder, Annona squamosa seed powder, their active components azadirachtin, allicin, hecogenin, acetogenin; herbal molluscicide pestoban and a synthetic m...

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...
