| telomere analysis of platyhelminths and acanthocephalans by fish and southern hybridization. | we examined the composition of telomeres in chromosomes of parasitic worms, representatives of the flatworm groups monogenea and cestoda (platyhelminthes), and thorny-headed worms (syndermata: acanthocephala) by fluorescence in situ hybridization (fish) with different telomeric repeat probes. our results show that the (ttaggg)n sequence, supposed to be the ancestral telomeric repeat motif of metazoa, is conserved in monogenea (paradiplozoon homoion) and cestoda (caryophyllaeus laticeps, caryophy ... | 2009 | 19935913 |
| endoparasites of chub (leuciscus cephalus) in two rivers of the abruzzo region of italy. | the relationship between communities of chub endoparasites (leuciscus cephalus) fished in the orta and pescara rivers in the abruzzo region of italy, and the quality of the water in which they are caught, were studied in surveys designed to evaluate the feed quality of fish in the inland waters of the abruzzo. samples were taken monthly from october 2000 to september 2001 in the orta river (buscesi district) and the pescara river (near the villareia bridge); a total of 86 chub were caught. durin ... | 2006 | 20429064 |
| [distribution of the cestode caryophyllaeides fennica (cestoda: lytocestidae) in the population of cyprinid fish in the rybinsk water reservoir]. | the distribution of the cestode caryophyllaeides fennica in populations of the ide, roach, white bream and bream from the rybinsk reservoir has been analyzed in regard to fish age. the relative abundance of c. fennica in populations of each host species was calculated as product of the helminthes abundance by the fish number in age groups. the highest prevalence and abundance of cestodes was found in the ide. all age classes of this species were infected, with the maximum in fishes of the age 3+ ... | 2003 | 12815814 |
| karyotype, chromosomal characteristics of multiple rdna clusters and intragenomic variability of ribosomal its2 in caryophyllaeides fennica (cestoda). | karyotype and chromosomal characteristics, i.e. number and location of ribosomal dna (rdna) clusters, and sequence variation of the ribosomal internal transcribed spacer 2 (its2) were studied in a monozoic (unsegmented) tapeworm, caryophyllaeides fennica (caryophyllidea), using conventional and ag-staining, fluorescent in situ hybridization (fish) with 18s rdna probe, and pcr amplification, cloning and sequencing of the complete ribosomal its2 spacer. the karyotype of this species was composed o ... | 2010 | 20466070 |
| checklist of tapeworms (platyhelminthes, cestoda) of vertebrates in finland. | a checklist of tapeworms (cestoda) of vertebrates (fishes, birds and mammals) in finland is presented, based on published observations, specimens deposited in the collections of the finnish museum of natural history (helsinki) and the zoological museum of the university of turku, and additional specimens identified by the present author. the checklist includes 170 tapeworm species from 151 host species, comprising 447 parasite species/host species combinations. thirty of the tapeworm species and ... | 2015 | 26668540 |
| plasma etching and ashing: a technique for demonstrating internal structures of helminths using scanning electron microscopy. | plasma etching and ashing for demonstrating the three-dimensional ultrastructure of the internal organs of helminths is described. adult worms of the cestode caryophyllaeides fennica were dehydrated through an ethanol series, critical point dried (polaron e3000) and sputter coated with 60% gold-palladium (polaron e5100) and glued to a standard scanning electron microscope (sem) stub positioned as required for ashing. after initial sem viewing of worm surfaces for orientation, stubs were placed i ... | 2006 | 16469178 |
