| the pathogenic helminth parasites of eels. | although 63 and 55 species of helminths have been reported from each species of atlantic eel and from 29 to 19 for each species of pacific eel only the monogeneans pseudodactylogyrus bini and p. anguillae and the nematode anguillicola crassus, originally specific to species of pacific eels, can be considered serious pathogens. none of the three are normally pathogenic to their preferred natural eel host species in the wild. pseudodactylogyrus spp. only cause serious local gill damage when presen ... | 2007 | 17498176 |

| microhabitat distribution of pseudodactylogyrus anguillae and pseudodactylogyrus bini among and within gill arches of the european eel (anguilla anguilla l.). | the outlying mean index (omi) method was used to test for seasonal microhabitat partitioning in pseudodactylogyrus anguillae and pseudodactylogyrus bini communities parasitising european eel ( anguilla anguilla l.) in four seasons. no differences in the occurrence of parasites were found in different seasons or on different gill arches. the omi analysis showed that hemibranch separation and gill segments were the main factors explaining the variation in parasite niche occupation for the first fa ... | 2003 | 12632166 |
| first report of the invasive eel pest pseudodactylogyrus bini in north america and in wild american eels. | we detected 2 species of monogenean gill worms, pseudodactylogyrus bini (kikuchi, 1929) gusev, 1965 and p. anguillae (yin & sproston, 1948) gusev, 1965 (monopisthocotylea: pseudodactylogyridae), on american eel anguilla rostrata in 2 rivers in south carolina, usa. one of these, p. anguillae, was reported 5 yr ago from nova scotia; as well as in south carolina, we also discovered it in 2 localities in chesapeake bay. differences in the morphologies of specimens of either species of worm from nort ... | 2001 | 11253875 |
| treatment of fish parasites. 10. effects of a new triazine derivative, hoe 092 v, on monogenea: a light and transmission electron microscopy study. | for chemotherapy of fish parasitized by monogeneans, a novel triazine derivative, 2-[3,5-alpha-dichloro-4-(4-methyl-sulfonylphenoxy)-phenyl]-1-methy l- hexahydro-1,2,4-triazine-3,5-dion (hoe 092 v), was tested in vivo against the gill- and skin-parasitizing species dactylogyrus extensus, d. vastator, and gyrodactylus arcuatus. naturally infected fish were incubated in aerated, separate tanks at 22 degrees c for 1, 2, 3, and 4 h in water containing 0, 1, 5, 10, or 15 micrograms hoe 092 v/ml, wher ... | 1993 | 8278338 |
| treatment of fish parasites. 4. effects of sym. triazinone (toltrazuril) on monogenea. | for chemotherapy in fish parasitized by monogeneans, toltrazuril was tested in vivo and in vitro against gill-parasitizing species (dactylogyrus vastator, d. extensus, d. cornu, pseudodactylogyrus anguillae, diplozoon paradoxum, dip. homoion) as well as the skin-parasitizing species gyrodactylus arcuatus. naturally infected fish were incubated at 20 degrees c for 0.3, 1, 2, 3, 4, and 6h in water containing 0.5, 10, 20, 30, and 50 microgram toltrazuril/ml. in general, the damage observed resulted ... | 1988 | 3237675 |

| divergence between asian, european and canadian populations of the monogenean pseudodactylogyrus bini indicated by ribosomal dna patterns. | the monogenean pseudodactylogyrus bini parasitizes the gills of eels belonging to the genus anguilla. circumstantial evidence suggests that the parasite has been spread accidentally from the pacific area (east asia) to europe by the intercontinental eel trade. this is based on early descriptions of the parasites from asian regions and the lack of records of the parasites in europe before 1977. in addition, the susceptibility of european eels to infections with the parasite is significantly highe ... | 2010 | 20230654 |
| low sensitivity of antemortem gill biopsies for the detection of subclinical pseudodactylogyrus bini infestations in american eels (anguilla rostrata). | the objectives of this study were twofold: to determine the sensitivity of gill biopsies used for the screening of pseudodactylogyrus bini in subclinically infested american eels (anguilla rostrata) and to evaluate the effect of bath anesthesia on the proportion of infested eels. fifty-four eels were euthanized following either intracoelomic injection of t61 or deep anesthesia with tricaine methanesulfonate. proportions of eels infested by p. bini diagnosed by gill biopsies taken through the gil ... | 2012 | 22448532 |
| three new species of pseudodactylogyrus (monogenea: pseudodactylogyridae) from australian eels. | three species of pseudodactylogyrus gusev, 1965 (monogenea: pseudodactylogyridae) were collected from the gills of anguilla reinhardtii steindachner and a. australis richardson from several localities in australia and eels imported to japan from australia. pseudodactylogyrus gusevi sp. n. from a. reinhardtii (type host) and a. australis in queensland, australia is most similar to p. bini (kikuchi, 1929), but can be differentiated by the shorter male copulatory tube, heavy sclerotisation of the v ... | 2015 | 26374824 |
| morphometric analysis of the hard parts of pseudodactylogyrus anguillae and pseudodactylogyrus bini (monogenea: dactylogyridae) on the gill apparatus of the european eels ( anguilla anguilla ) from the freshwaters of latvia. | we investigated the spatial distribution and measured the hard parts of the attachment apparatuses and reproductive organs of the 2 eel-specific monogenean species pseudodactylogyrus anguillae and pseudodactylogyrus bini. comparative analysis focused on parasite microhabitats within the gill apparatus. additionally, we compared the morphometric characteristics of the monogeneans based on geographical locality and seasonality. the attachment apparatus and reproductive organ characteristics of the ... | 2016 | 26741978 |
| relationship between european eel anguilla anguilla infection with non-native parasites and swimming behaviour on encountering accelerating flow. | the effect of anguillicola crassus, pseudodactylogyrus bini and pseudodactylogyrus anguillae infection on the behaviour of downstream migrating adult european eels anguilla anguilla as they encountered accelerating water velocity, common at engineered structures where flow is constricted (e.g. weirs and bypass systems), was evaluated in an experimental flume. the probability of reacting to, and rejecting, the velocity gradient was positively related to a. crassus larval, adult and total abundanc ... | 2015 | 25801939 |
| surface features of the monogenean gill parasites pseudodactylogyrus anguillae and pseudodactylogyrus bini from the european eel anguilla anguilla in egypt. | in the present study, scanning electron microscopy is used to demonstrate the surface features of pseudodactylogyrus anguillae yin and sproston (1948) gussev, 1965 and pseudodactylogyrus bini kikuchi (1929) gussev, 1965 from the european eel anguilla anguilla. specimens of the eel a. anguilla were collected from the river nile, near mansoura, dakahlia province, egypt. morphologically, p. anguillae could be distinguished from p. bini based on the total length, the shape and size of the haptor, an ... | 2011 | 21647675 |
| parasite communities in eels of the island of reunion (indian ocean): a lesson in parasite introduction. | eel populations from the small rivers on the island of reunion (french overseas department in the indian ocean) were investigated with respect to the occurrence and abundance of helminths during the autumn of 2005. the native species anguilla marmorata (n = 80), anguilla bicolor (n = 23), and anguilla mossambica (n = 15) were studied. six species of helminths were identified, four of them having a definitely nonnative status. furthermore, unidentified intra-intestinal juvenile cestodes and extra ... | 2008 | 18288491 |
