water snails as paratenic hosts of hymenolepididae fuhrmann, 1907 in czechoslovakia.the distribution of cysticercoids of hymenolepididae fuhrmann, 1907 parasitizing water birds (anseriformes and ralliformes) in czechoslovakia was studied. a total of 2970 snail specimens (429 lymnaea stagnalis (l.), 531 l. ovata (drap.), 1, 462 l. peregra (o. f. müll.), 158 l. auricularia (l.), 262 planorbis planorbis (l.) and 65 viviparus viviparus (l.)) were examined for this purpose. among them, 122 snails were infected with cysticercoids of 13 cestode species (dicranotaenia coronula (dujardi ...19863758867

[biology of cestodes of domestic ducks and wild water birds].life cycles of 16 cestode species of the families hymenolepididae and diploposthidae were studied in 52 ponds of the state fishery in bohemia and moravia. the parasites were recovered from domestic ducks kept on the ponds and from wild birds, mostly of the genera anas and aythya, occurring in these water biotopes. cestode larvae were found in 9 species of copepoda (9669 out of 1 600 200 examined specimens, i. e. 0.6%) and 3 species of ostracoda (500 out of 272 300 examined specimens, i. e. 0.18% ...19836417876
[helminth fauna anseriformes (aves) in the lodz zoological garden].in the years 1959-1990 429 birds on 30 species of anseriformes were examined post mortem at zoo lódź. the helminths were found in 108 birds (25.17%) of 19 species. in infected birds there were found 4 species of trematodes: one of them, catatropis verrucosa is in poland new for cygnus olor; 9 species of cestodes--7 of them are in poland new for examined hosts; namely: drepanidotaenia lanceolata for dendrocygna viduata, cygnus atratus, branta bernicla, and anas platyrhynchos; microsomacanthus par ...19979424942
fimbriaria fasciolaris and cloacotaenia megalops (eucestoda, hymenolepididae), cestodes from brazilian waterfowl.two cestode species, fimbriaria fasciolaris (pallas, 1781) frölich, 1802 cloacotaenia megalops (nitzsch in creplin, 1829) wolffhügel, 1938 collected from anas bahamensis linné, 1758 and amazonetta brasiliensis (gmelin, 1758) in lagoons of the maricá district, state of rio de janeiro, brazil, are described. this is the first record of f. fasciolaris parasitizing a. bahamensis. the prevalence, intensity of infection, and mean intensity of infection for both species are given. overdispersion distri ...19989921301
transmission electron micrograph studies of developing oncospheral envelopes of fimbriaria fasciolaris (hymenolepididae).studies of the ultrastructure of oncospheral envelopes of fimbriaria fasciolaris in utero using transmission electron microscopy revealed three primary layers: uterine, outer and inner envelopes. a capsule was not found. the uterine envelope surrounds up to 12 oncospheres enclosed by the outer and inner oncospheral envelopes. the secondary envelopes arise during the embryos' development and, in part, are formed in a way different from that described for other hymenolepididae. a thin, folded shel ...19911924257
