| the life cycle of rubenstrema opisthovitellinum sołtys, 1954 (trematoda: omphalometridae). | the life cycle of rubenstrema opisthovitellinum sołtys, 1954, a parasite of shrews, is elucidated. the following developmental stages are described in detail: daughter sporocyst, cercaria, metacercaria, and adult. the freshwater snail planorbarius corneus was found to be the first intermediate host in nature. the metacercariae were obtained from the larvae of mosquitoes culex molestus and only exceptionally from snails physa acuta. the adults were obtained from the small intestine of hamsters me ... | 1991 | 1808031 |
| symptoms of behavioural anapyrexia--reverse fever as a defence response of snails to fluke invasion. | the subject of the research was the thermal preferences of planorbarius corneus individuals infected by larvae of digenetic trematodes. snails were obtained over two consecutive years, 2009 and 2010, from 10 water bodies located in central poland. the relationship between the seasons and the occurrence of patent invasions in hosts found in the shore-zone of lakes was observed. behavioural experiments conducted on p. corneus individuals placed in a thermal gradient demonstrated that parasite infe ... | 2012 | 22244795 |
| invaders of an invader--trematodes in potamopyrgus antipodarum in poland. | the subject of the following study was the natural and experimental invasion of trematode larvae in potamopyrgus antipodarum from bory tucholskie national park (poland). only one out of the 14,908 dissected specimens had oval sporocysts and mature cercariae of fish fluke, which belongs to the sanguinicolidae family. it is the first recorded case in the european population of p. antipodarum living in inland water. the experimental study showed the possibility of native metacercariae (echinostoma ... | 2009 | 19249307 |
