| [ecology of lymnaea truncatula müller, intermediate host of fasciola hepatica linné in the microclimate of tozeur (southeast of tunisia)]. | systematic visits were carried out in the traditional tozeur' oasis (tunisia), in 1997/1998 in order to study the ecology of lymnaea truncatula as well as its density in relation to habitat characteristics in the hydrographical networks of the oases. lymnaea truncatula was enumerated on 1 m2 surface by habitat, according to the quadrat method. samples of soil, irrigation and draining water were also analysed. the density of lymnaea truncatula detected in autumn was constantly higher. it depends ... | 1999 | 10690463 |
| [natural infestation of lymnaea truncatula muller by fasciola hepatica in the tozeur oasis in southwest tunisia]. | natural infestation of lymnaea truncatula by fasciola hepatica was studied at various sites in the traditional oasis of tozeur 8 times between september 1997 and august 1998. infestation of snails was documented in five of the eight sites with a mean level of 26.1 p. 100. level of infestation varied depending on the site. it was highest in secondary irrigation canals (32.8 p. 100), seguias, (34.8 p. 100), and secondary drainage canals (34.8 p. 100). lower levels were observed in the main drainag ... | 2000 | 11100443 |
| molluscicidal and antiparasitic activity of solanum nigrum villosum against galba truncatula infected or uninfected with fasciola hepatica. | the present study was based on assessments of the molluscicidal and antiparasitic activities of solanum nigrum villosum. this plant has been collected in tozeur's traditional oases (south-western tunisia). molluscicidal activities of leaves, ripe fruit and unripe fruit extracts of s. n. villosum have been assessed in experimental and semi-field conditions on uninfected galba truncatula. antiparasitic activities have also been assessed on larval stages (rediae, intraredial germinal masses and cer ... | 2008 | 18462554 |
