the invasive fish tapeworm atractolytocestus huronensis (cestoda), a parasite of carp, colonises africa.	biological invasions represent a serious threat for aquaculture because many of introduced parasites may negatively affect the health state of feral and cultured fish. in the present account, the invasive tapeworm atractolytocestus huronensis anthony, 1958 (cestoda: caryophyllidea), which was originally described from north america and has been introduced to europe including the british isles with its specific host, common carp (cyprinus carpio l.), is reported from africa for the first time. it ...	2015	26091762
the tapeworm atractolytocestus tenuicollis (cestoda: caryophyllidea)--a sister species or ancestor of an invasive a. huronensis?	atractolytocestus tenuicollis (li, 1964) xi, wang, wu, gao et nie, 2009 is a monozoic, non-segmented tapeworm of the order caryophyllidea, parasitizing exclusively common carp (cyprinus carpio l.). in the current work, the first molecular data, in particular complete ribosomal internal transcribed spacer 2 (its2) and partial mitochondrial cytochrome c oxidase subunit i (cox1) on a. tenuicollis from niushan lake, wuhan, china, are provided. in order to evaluate molecular interrelationships within ...	2013	23832640
population study of atractolytocestus huronensis (cestoda: caryophyllidea), an invasive parasite of common carp introduced to europe: mitochondrial cox1 haplotypes and intragenomic ribosomal its2 variants.	the invasive monozoic tapeworm atractolytocestus huronensis, a specific parasite of common carp, was originally found and described in the north american continent. it has been introduced to europe and reported in several countries in the last 15 years, as well. in the current study, tapeworms from one north american (usa) and five european localities (united kingdom/uk, slovakia, hungary, croatia, and romania) were subjected to molecular analyses in order to determine the level of intrapopulati ...	2011	21210151
Molecular characterization of Atractolytocestus sagittatus (Cestoda: Caryophyllidea), monozoic parasite of common carp, and its differentiation from the invasive species Atractolytocestus huronensis.	Sequence structure of complete internal transcribed spacer 1 and 2 (ITS1 and ITS2) of the ribosomal DNA region and partial mitochondrial cytochrome c oxidase subunit I (cox1) gene sequences were studied in the monozoic tapeworm Atractolytocestus sagittatus (Kulakovskaya et Akhmerov, 1965) (Cestoda: Caryophyllidea), a parasite of common carp (Cyprinus carpio carpio L.). Intraindividual sequence diversity was observed in both ribosomal spacers. In ITS1, a total number of 19 recombinant clones yiel ...	2011	21987104
intra-individual internal transcribed spacer 1 (its1) and its2 ribosomal sequence variation linked with multiple rdna loci: a case of triploid atractolytocestus huronensis, the monozoic cestode of common carp.	complete sequences of the ribosomal internal transcribed spacers (its1 and its2) and karyological characters of the monozoic (unsegmented) tapeworm atractolytocestus huronensis anthony, 1958 (cestoda: caryophyllidea) from slovakia were analysed, revealing considerable intra-genomic variability and triploidy in all analysed specimens. analysis of 20 sequences of each its1 and its2 spacer yielded eight and 10 different sequence types, respectively. in individual tapeworms, two to four its1 and thr ...	2010	19651130
vitellogenesis in the cestode atractolytocestus huronensis anthony, 1958 (caryophyllidea: lytocestidae).	vitellogenesis in the parthenogenetic caryophyllidean tapeworm atractolytocestus huronensis anthony, 1958, parasitizing the carp cyprinus carpio l., has been examined using light (lm) and transmission electron microscopy and cytochemical staining with periodic acid-thiosemicarbazide-silver proteinate for glycogen. it was found that formation of vitellocytes shares the same basic patterns in lower tapeworms with parthenogenetic and normal reproduction. each vitelline follicle of a. huronensis con ...	2009	19352702
ultrastructural aspects of spermatogenesis, testes, and vas deferens in the parthenogenetic tapeworm atractolytocestus huronensis anthony, 1958 (cestoda: caryophyllidea), a carp parasite from slovakia.	spermatogenesis, testes, and vas deferens in the parthenogenetic monozoic tapeworm atractolytocestus huronensis anthony, 1958 (cestoda: caryophyllidea) from slovakia, parasitizing the carp cyprinus carpio l., have been investigated by means of transmission electron microscopy for the first time. the present results show that helminths with parthenogenetic and normal reproduction may share some common spermatology features, e.g., dense cytoplasm of the peripherally localized spermatogonia or a ro ...	2011	20838810
re-establishment of the fish parasite fauna in the tisa river system (slovakia) after a catastrophic pollution event.	an extensive survey of helminth parasites in 1,316 freshwater fish representing 31 species from two aquatic ecosystems in southeastern slovakia characterized by different level of environmental pollution was carried out. the helminth species diversity was compared between the tisa river, heavily polluted with cyanides and heavy metals after a series of ecological disasters in 2000, and the less anthropogenically influenced latorica river. a parasitological survey found 31 gastrointestinal helmin ...	2009	19214574
tapeworm khawia sinensis: review of the introduction and subsequent decline of a pathogen of carp, cyprinus carpio.	the asian tapeworm khawia sinensis hsü, 1935 (cestoda: caryophyllidea) is a large-sized (body length up to 11.5 cm) monozoic (unsegmented) parasite of common carp (cyprinus carpio l.) that may cause mortality of young fish (fry). since the 1960s, this cestode successfully colonized a large part of europe, including the british isles, north america and japan. however, a review of published records provides evidence that the tapeworm k. sinensis, invasive parasite of carp, has become less common d ...	2009	19520514
Early intrauterine embryonic development in Khawia sinensis Hsü, 1935 (Cestoda, Caryophyllidea, Lytocestidae), an invasive tapeworm of carp (Cyprinus carpio): an ultrastructural study.	Intrauterine embryonic development in the caryophyllidean tapeworm Khawia sinensis has been investigated using transmission electron microscopy and cytochemical staining with periodic acid-thiosemicarbazide-silver proteinate for glycogen. Contrary to previous light microscopy findings that reported the release of non-embryonated eggs of K. sinenesis to the external environment, the present study documents various stages of embryonation (ovoviviparity) within the intrauterine eggs of this cestode ...	2011	21894510
occurrence of atractolytocestus huronensis (cestoda, caryophyllaeidae) in german pond-farmed common carp cyprinus carpio.	up to now, the caryophyllid cestode atractolytocestus huronensis anthony, 1958, a parasite of common carp, has attracted little attention in germany. based on recent publications from the czech republic and hungary, it appears probable that this cestode may be increasingly common in germany. there is a strong connection between the occurrence of a. huronensis and imports of common carp from the czech republic and southern germany. although in most cases no clinical alterations in parasitized car ...	2006	16903238
the cestode atractolytocestus huronensis (caryophyllidea) continues to spread in europe: new data on the helminth parasite of the common carp.	the caryophyllidean tapeworm atractolytocestus huronensis anthony, 1958, originally described from the common carp cyprinus carpio carpio l. from north america, has recently been introduced into europe (uk, hungary). in the present study, the dispersion of the tapeworm in other countries of central europe (slovakia and the czech republic) is described, including its first observation in the common carp of the tisa river, southeastern slovakia. because of the transboundary location of the river, ...	2004	15648838
