Nine polymorphic microsatellite loci were characterized from the freshwater trematode Coitocaecum parvum . This parasite can either reproduce sexually in the definitive host or produce eggs by selfing inside its second intermediate host. Two to 11 alleles per locus were detected in 24 trematode sporocysts and observed heterozygosities ranged from 0.04 to 0.96. These loci will be useful for iden...

Since its use as a model to study metazoan parasite culture and in vitro development, the plerocercoid of the tapeworm, Ligula intestinalis, has served as a useful scientific tool to study a range of biological factors, particularly within its fish intermediate host. From the extensive long-term ecological studies on the interactions between the parasite and cyprinid hosts, to the recent advanc...

Pomphorhynchus laevis, a fish acanthocephalan parasite, manipulates the behaviour of its gammarid intermediate host to increase its trophic transmission to the definitive host. However, the intensity of behavioural manipulation is variable between individual gammarids and between parasite populations. To elucidate causes of this variability, we compared the level of phototaxis alteration induce...

  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...
