| [phyletic affinities among polystomatidae (monogenea)]. | the chaetotaxy and ciliated cells in two monogenean larvae of marine fishes are described for the first time: a monopisthocotylea diplectanum aequans (wagener, 1857) diesing, 1858 parasite of dicentrarchus labrax (l) and a polyopisthocotylea, microcotyle mormyri lorenz, 1878 parasite of pagellus mormyrus (l). a comparative study with the known larvae shows evidence of two larval types in the monogenea of fishes, related to the two great phyla of the class: the monopisthocoytylea and polyopisthoc ... | 1977 | 413661 |
| [the oncomiracidium of ancyrocephalus paradoxus creplin, 1839 (monongenea, monopisthocotylea), parasite of sander lucioperca (teleostei, percidae)]. | the distribution of ciliated cells and the oncomiracidium chaetotaxy in ancyrocephalus paradoxus creplin, 1839 (ancyrocephalidae) parasite of sander lucioperca (teleostean, percidae) are described for the first time as well as the larval ciliated cells in dactylogyrus extensus (dactylogyridae) parasite of cyprinus carpio. also is given a description of the larval haptorial armature of ancyrocephalus paradoxus which shows some original features in our region. the ciliated cell pattern and chaetot ... | 1977 | 603199 |
| [viral infection in a platyhelminth parasite]. | in parenchyme cells of the parasitic plathelminthe diplectanum aequans virus-like cytoplasmic particles were observed. their formation is noted in virogenic areas and they are often gathered in regular geometric arrangements. the infected cells show important lesions. | 1976 | 827365 |
| [gill repartition of two monogenea: diplectanum aequans (wagener 1857), diesing 1958 and d. laubieri lambert and maillard 1974 (monogenea, monopisthocotylea) simultaneous parasites of the sea bass dicentrarchus labrax (author's transl)]. | the close observation of the gill habitat of two monogeneans diplectanum aequans (wagener 1857) diesing 1858 and diplectanum laubieri lambert and maillard 1974 shows the microbiotopes of these two simultaneous parasites of the sea-bass: dicentrarchus labrax. the authors propose to study the distribution of the monogeneans with references to three theoretic axes in the gill chambers. for the diplectanum, the populations spread on each of these axes according to preferential gradients. | 1975 | 1227377 |

| hyperparasitism of trichodinid ciliates on monogenean gill flukes of two marine fish. | two unusual cases of hyperparasitism of trichodinid ciliates on monogenean gill flukes are described from southern israel (red sea). the first case occurred in cultured european sea bass dicentrarchus labrax infected by diplectanum aequans, while the second was observed in a feral devil firefish pterois miles infected by haliotrema sp. in both cases, the trichodinids heavily co-infested the host fish gills. the flukes were completely coated by the ciliates, which gave them a cobblestone appearan ... | 2005 | 16060271 |
| gill histopathology of cultured european sea bass, dicentrarchus labrax (l.), infected with diplectanum aequans (wagener 1857) diesing 1958 (diplectanidae: monogenea). | the mortality of juvenile european sea bass, dicentrarchus labrax (l.), in the spring of the last 5 years in the northern coast of the adriatic sea has been attributed to heavy infections of the gill monogenean diplectanum aequans (wagener 1857) diesing 1858. the histopathological examination of 38 sets of gills from hosts measuring 16.46 +/- 0.26 cm in total length (mean+/-s.e.) and weighing 45.98 +/- 2.37 g (mean+/-s.e.) were conducted using light and transmission electron microscopy. twenty-e ... | 2007 | 17061113 |
| dynamic expression of immune response genes in the sea bass, dicentrarchus labrax, experimentally infected with the monogenean diplectanum aequans. | the sea bass, dicentrarchus labrax, is one of the most extensively farmed marine fishes in the mediterranean. under the high-density condition common in aquaculture, the monogenean gill parasite diplectanum aequans can cause significant economic losses. this study used real-time quantitative pcr to investigate the dynamic expression of immune response genes in sea bass infected with diplectanum aequans. the target genes, interleukin-1 (il-1beta, transforming growth factor (tgf-beta and t-cell re ... | 2008 | 18396061 |
| immunocytochemical localization of piscidin in mast cells of infected seabass gill. | annual losses of approximately 5-10% of the juvenile stock of european seabass, dicentrarchus labrax (l.) in the northern coast of the adriatic sea has been attributed to heavy infections of the gill monogenean diplectanum aequans. immunocytochemical, light and ultrastructural studies were carried out on seabass naturally parasitized with this monogenean. the site of the worm's attachment was marked by the common presence of haemorrhages and white mucoid exudate. in histological sections, infect ... | 2010 | 20034572 |
| influence of season and site location on european cultured sea bass parasites in corsican fish farms using indicator species analysis (indval). | the parasites of 536 european sea bass, dicentrarchus labrax, were studied between january 2012 and december 2013 in six corsican fish farms. the indicator value (indval) method, which combines measures of fidelity and specificity, has been used in this study. because of its resilience to changes in abundance, indval is a particularly effective tool for ecological bioindicator. the indval method showed how season can influence the occurrence of parasite species in cultured sea bass and also iden ... | 2016 | 26446088 |
