Long-term effects of dinoseb and paraquat, both individually and combined, on embryonic development and hatching success of Fasciola hepatica miracidia.

Further Observation on the Susceptibility of Different Species of Lymnaea Snails of Iran to Miracidia of Fasciola hepatica and Fasciola gigantica

Extremely low frequency magnetic field and the hatching rate of Fasciola hepatica eggs, the fecundity and survival of liver fluke-infected snail, Lymnaea truncatula.

Eggs of Fasciola hepatica were exposed for 10 days to extremely low frequency magnetic field (ELFMF) at the frequency of 50 Hz and density of 2 mT (rms). The results show an accelerated hatching of F. hepatica eggs in relation to control (non-exposed) group. The host snails, Lymnaea truncatula, were divided into three groups; those of groups I and II were infected with the miracidia of F. hepat...

The effect of saprotrophic fungi on the development and hatching of Fasciola hepatica eggs.

The aim of this study was to determine the effect of 6 common soil fungi species: Alternaria alternata (Fr.) Keissl., Aspergillus candidus Link, Penicillium chrysogenum Thom, P. commune Thom, Trichothecium roseum (Pers.) Link and Ulocladium sp., on the hatching of miracidia, i.e., free living larvae of liver fluke (Fasciola hepatica). To this end, the eggs of F. hepatica were incubated in water...

Inhibition Effect of pH on the Hatchability of Fasciola Miracidia under Laboratory Conditions.

BACKGROUND Fasciolosis, caused by the liver flukes of the genus Fasciola, is one of the most prevalent diseases of domestic livestock and human throughout the world, imposing considerable economic losses. The present study was aimed to assess the effects of different pH values on hatching rate of Fasciola miracidia. METHODS The flukes were isolated from the infected livers of the slaughtered ...

Fasciola hepatica: comparative metacercarial productions in experimentally-infected Galba truncatula and Pseudosuccinea columella

As large numbers of metacercariae of Fasciola hepatica are necessary for research, experimental infections of Galba truncatula and Pseudosuccinea columella with this digenean were carried out to determine the better intermediate host for metacercarial production and, consequently, the most profitable snail for decreasing the cost price of these larvae. Pre-adult snails (4 mm in shell height) or...
