Fish-borne Trematodes in Vietnam
From 1976 to 2000, over 30,000 human stool samples from 38 communes in 15 provinces were examined. The average infection rate of Clonorchis and Opisthorchis in the provinces examined was 21%. In these provinces, the infection rates were distributed as follows: 0.6% in Ha Giang, 0.2% in Thai Binh, 16.3% in Bac Giang, 13.1% in Hai Phong, 5% in Hoa Binh, 16% in Ha Tay, 3-37.5% in Nam Dinh, 3% in H...
متن کاملElectroretinographically-determined scotopic spectral sensitivities of some marine fish.
INTRODUCTION BOTH BURKHARDT (1966) and WITKOVSKY (1968) used the electroretinogram to determine the dark-adapted spectral sensitivity of the gold&h and carp, respectively. They found that the b-wave was much more sensitive to long wavelengths than one would predict from the absorption spectrum of carp porphyropsin (CRESCITELLI and DARTNALL, 1954). They suggested that the cones were responsible ...
متن کاملSome digenetic trematodes from synaphobranchid eels.

متن کاملPrevention and Control of Fish-borne Zoonotic Trematodes in Fish Nurseries, Vietnam
Worldwide, >18 million persons were infected with fish-borne zoonotic trematodes in 2002. To evaluate the effectiveness of interventions for reducing prevalence and intensity of fish-borne zoonotic trematode infections in juvenile fish, we compared transmission rates at nurseries in the Red River Delta, northern Vietnam. Rates were significantly lower for nurseries that reduced snail population...
متن کاملPrevalence of zoonotic trematodes in fish from a Vietnamese fish-farming community.
The prevalence of fish-borne zoonotic trematode (FZT) metacercariae was investigated in fish farmed by rural households in Nghe An Province, located in northern Vietnam. In total, 716 fish, including tilapia (Oreochromis niloticus) and 6 carp species, i.e., grass carp (Ctenopharyngodon idellus), bighead carp (Aristichthys nobilis), mrigal (Cirrhinus mrigala), common carp (Cyprinus carpio), silv...
