| Trichodinid (Ciliophora: Trichodinidae) Infections in Perch (Perca fluviatilis) Experimentally Exposed to Pulp and Paper Mill Effluents. | Wild-caught European perch (Perca fluviatilis) were exposed in the laboratory to untreated bleached pulp and paper mill effluent in two separate experiments. The first experiment was conducted at 7-8°C using effluent concentrations of 5 and 10%, and the second experiment was conducted at ambient river temperature of 4-20°C using an effluent concentration of 1%. Trichodinid ciliates were identified and enumerated at the end of the exposure using a mucus subsampling technique from gill and skin as ... | 2011 | 22143942 |
| parasite infections in danish trout farms. | samples from 5 danish freshwater trout farms rearing rainbow trout (oncorhynchus mykiss) were examined for parasite infections from october 1993 until november 1994 and recorded parasites are listed. in addition, results from an examination of a mariculture net cage system are presented as well. a total of 10 metazoan and 10 protozoan parasites were recorded. the metazoans included gyrodactylus derjavini, gyrodactylus salaris, eubothrium crassum, triaenophorus nodulosus, proteocephalus sp., dipl ... | 1995 | 7502946 |
| gross and microscopic pathological changes associated with parasitic infection in european eel (anguilla anguilla, linnaeus 1758). | the gross pathological and histopathological changes associated with parasitic infection in the european eel (anguilla anguilla linnaeus, 1758) was investigated. a total of 65 eels collected from three sampling localities in eastern delta, egypt were examined over the period of january-may 2008. the fish were subjected to standard procedures for parasitological and pathological examinations. overall, 22 (33.8%) of the 65 fish examined were found to have parasitic infections. the eels harbored a ... | 2010 | 19953271 |
| parasite fauna of the eel, anguilla anguilla (linnaeus, 1758), from the polish part of the vistula lagoon. | eel is one of the most valuable commercial fish species of the vistula lagoon. for this reason its infection by non-indigenous species of parasites is the subject of the interest of sciencists. | 2006 | 17120993 |
| trichodinid ectoparasites (ciliophora: peritrichida) of some river nile fish, egypt. | four species of trichodinid ectoparasites (ciliophora: peritrichida) were collected from the gills of the following river nile fish in egypt: hydrocynus forskalii, mormyrus kannume, schilbe mystus. these species are: trichodina heterodentata duncan, 1977, trichodina fahaka sp. n., trichodinella epizootica raabe, 1950, tripartiella dactylodentata sp. n. photomicrographs and morphometric data are presented for each species. | 2000 | 10882902 |
| use of protozoan communities for pollution monitoring. | a gradient of chronic organic pollution was identified in a small river in south-east england. the parasite fauna of the ubiquitous three-spined stickleback (gasterosteus aculeatus l.) was studied at the extremes of the pollution gradient and trichodinid ciliates identified as a potential bioindicator. a simple technique was developed for the quantification of whole body-burdens of trichodinids on small fish. three species of trichodinids were identified: trichodina domerguei, t. tenuidens and t ... | 1997 | 9802068 |
| phylogenetic analyses of trichodinids (ciliophora, oligohymenophora) inferred from 18s rrna gene sequence data. | partial 18s rrna gene sequences of the three trichodinids, namely trichodina modesta lom, 1970, trichodina paraheterodentata tang and zhao 2012. and trichodinella epizootica (raabe 1950) šrámek-hušek, 1953, were acquired and used to construct phylogenetic trees. the results revealed that trichodinella epizootica clustered with trichodinella sp.; trichodina paraheterodentata tang and zhao 2012 was sister to the clade composed of trichodina heterodentata duncan, 1977 and trichodina nobilis chen, 1 ... | 2013 | 23196703 |
| first report of some known trichodinella epizootica šramek-hušek, 1953, <br />and tripartiella lom, 1959 from the cultured oranda gold fish (carassius auratus auratus) in india. | trichodiniasis of fishes cause economic losses in the fish industry through mortality and decrease growth rate. very few studies of these ectoparasites have been made in india. a comprehensive icthyoparasotological survey in some ornamental fish farms of different parts of india has been done since march 2014-may 2015. during the study these trichodinid parasites have been identified from the gills of oranda gold fish (carassius auratus auratus l.). they are trichodinella epizootica, tripartiell ... | 2016 | 27811658 |
| [parasite fauna of the european river lamprey lampetra fluviatilis (l.) from lake onega]. | data on the parasite fauna of the adult european river lamprey lampetra fluviatilis (l.) from lake onega are reported. ten parasite species are found, including trematodes diplostomum petromyzifluviatilis and d. spathaceum (metacercariae), cestode proteocephalus longicollis, nematodes cucullanus truttae and raphidascaris acus, acanthocephalan echinorhynchus salmonis, ectoparasitic infusoria chilodonella hexastica, trichodina tenuidens, and trichodinella epizootica, and fungus saprolegnia parasit ... | 2007 | 17957959 |
| parasite fauna of selected fish species of lake miedwie. | a total of 136 fishes, representing 9 species (perch, perca fluviatilis l.; pike, esox lucius l.; european eel, anguilla anguilla (l.); common bream, abramis brama (l.); roach, rutilus rutilus (l.); tench tinca tinca (l.); european whitefish, coregonus lavaretus (l.); vendace, coregonus albula (l.); and zander, sander lucioperca (l.)), from lake miedwie were studied within 1997-1999. the necropsies yielded 41 parasite species (taxa). the most diversified were parasite faunas of pike (19 parasite ... | 2002 | 16888943 |
