| chaetotaxy of cercariae of opisthioglyphe ranae (frölich, 1791) (trematoda: plagiorchidae). | a detailed observation of the sensory apparatus of opisthioglyphe ranae (frölich, 1791) cercariae was carried out. the species was determined on the basis of an experimental study of the life cycle and morphology of sporocysts, cercariae, metacercariae, and adults. in contrast to other species of the family plagiorchidae, no papillae were present in the positions cid1, cid2, cii0, cii3 and cii4. papillae with markedly ventral situation on the postacetabular zone were found very rarely. some of t ... | 1989 | 2583616 |
| [investigations on dynamics of somatic growth in juvenile snails lymnaea stagnalis (pulmonata: basommatophora) in conditions of experimental infection with parthenites of the trematode opisthioglyphe ranae (digenia: plagiorchiida)]. | the effect of exposure of juvenile individuals of lymnaea stagnalis to infectious eggs of opisthioglyphe ranae on dynamics of their growth was investigated under controlled conditions in laboratory. in infected snails enlargement of body weight and linear parameters of shell were observed. any differences in shell shape, analysed on the base of regression of shell width towards to its height, were not ascertained in uninfected snails and those infected with parthenites of the trematode. the find ... | 1994 | 7801640 |
| [investigations on the pathogenesis of changes in somatic growth of lymnaea stagnalis (gastropoda:pulmonata) experimentally infected with parthenites of trematode opisthioglyphe ranae (digenea:plagiorchiida). ii. karyometry and aerobic metabolism of the neurosecretory cells]. | enlargement of nuclear volume of the neurosecretory cells producing growth hormone (light green cells of cerebral ganglia) was observed in experimentally infected snails. in addition to noted earlier increase in the amounts of: neurosecretory material, rna and the loose fraction of nuclear chromatin in the perikarya, it can be the next argument for the influence of the parasite on the activity of the hormonal system cells of its intermediate host. found in infected individuals, the increase in t ... | 1996 | 8967076 |

| larval trematodes in freshwater molluscs from the elbe to danube rivers (southeast germany): before and today. | studies on life cycles of trematodes have a long tradition in germany; (odening 1978) listed a total of 177 trematodes, which can potentially complete their life cycles in german inland waters. however, almost no recent data on the occurrence of larval stages in molluscs are available. therefore, a survey of trematodes in southeast germany was carried out in 2004. a total of 31 species of ten families (29 species of cercariae, seven species of metacercariae, and five species found of both) were ... | 2006 | 16670883 |
| digenea species in chosen populations of freshwater snails in northern and central part of poland. | background: the aim of this work was to determine the biodiversity of digenean larvae in the snail populations from various water bodies. material and methods: snails under study were collected from 29 reservoirs situated in northern and central part of poland. during the period 1999-2005 10.581 snails from 6 species (among which two species dominated: lymnaea stagnalis--9.469, and planorbarius corneus--737 specimens) were examined for shedding cercariae. the total number of 4.404 molluscs was p ... | 2007 | 18441876 |
| [age structure and dynamics of abundance of the adult trematode opisthioglyphe ranae (fasciolida, plagiorchidae) hemipopulation in lake frog from the saratov reservoir]. | age structure and dynamics of abundance of adult opisthioglyphe ranae, a parasite of intestine of lake frog, are analyzed. in the period of activity of the host (may-october), the hemipopulation of o. ranae maritae is represented by two generations, which are situated in host lesser than one year and differ from each other in the rate of maturation. | 2009 | 20198966 |
| larval trematodes (digenea) of the great pond snail, lymnaea stagnalis (l.), (gastropoda, pulmonata) in central europe: a survey of species and key to their identification. | a survey of cercariae and metacercariae (trematoda, digenea) from the great pond snail (lymnaea stagnalis) in central europe (austria, czech republic, south-east germany, poland and slovak republic) is presented, based on a study of 3,628 snails examined from 1998 to 2005. a total of 953 (26.3%) l. stagnalis were infected with 24 trematode species comprising 19 species of cercariae and 11 species of metacercariae (six species occurred both as cercarie and metacercarie) of eight families. the dom ... | 2007 | 17432056 |
| differences in shell shape of naturally infected lymnaea stagnalis (l.) individuals as the effect of the activity of digenetic trematode larvae. | the shells of lymnaea stagnalis show great morphological variability. this phenomenon has been described as the result of an environmental influence. the main object of the present study was to compare some biometric data from shells of naturally infected and uninfected snails from 25 different lakes in the central part of poland. the height of the shell, the height of the spiral, and the width of the shell were measured. some inter- and intrapopulation differences among individuals were found. ... | 2005 | 16419747 |
| [investigations on the pathogenesis of changes in somatic growth of lymnaea stagnalis (gastropoda: pulmonata) experimentally infected with parthenites opisthioglyphe ranae (digenea: plagiorchiida). i. relative weight of accessory sex organs and synthetic activity of neurosecretory cells]. | in the paper an attempt to define pathogenesis of changes in somatic growth of juvenile individuals of the popular freshwater snail lymnaea stagnalis experimentally infected with parthenites of the trematode opisthioglyphe ranae was undertaken. significant enlargement of relative wet weight of examined accessory sex organs (albumen gland, oothecal gland, prostate, male copulatory organ) observed in infected snails permits to explain increase of their somatic growth basing on the hypothesis of di ... | 1996 | 8755148 |
