Abstract:
L’étude de la parasitofaune branchiale de 558 Barbus martorelli a été menée dans un cours d’eau douce aux alentours de Yaoundé (Cameroun) en milieu tropical, afin d’obtenir des informations sur la répartition des agents pathogènes dans une population d’hôtes sauvages ; ces données sont indispensables dans la recherche de moyens pour éviter les pertes énormes souvent observées en pisciculture intensive. Cette analyse a révélé la présence de deux espèces de myxosporidies (Myxobolus barbi et M. njinei) et de huit espèces de monogènes (Dactylogyrus bopeleti, D. insolitus, D. simplex, D. maillardi, Dogielius martorellii, Dogielius sp., une espèce de Gyrodactylidae et une larve de Polystomatidae). Quatre poissons n’ont pas présenté de parasites, 24 ont présenté une infection monospécifique et 530 une infection plurispécifique. Chaque individu infesté a hébergé en moyenne quatre espèces de parasites. Alors que la prévalence et l’intensité moyenne parasitaire diminuaient avec la taille de l’hôte pour les protozoaires, le phénomène inverse a été observé pour les helminthes. L’effet sexe a été noté dans l’infestation de B. martorelli par la myxosporidie M. njinei et par la plupart des espèces de monogènes. Les femelles ont ainsi été plus infestées que les mâles en raison de leur biologie en période de frai. Enfin, la richesse des espèces parasitaires a semblé affecter négativement le poids des hôtes.

Abstract:
Mullets (Mugilidae) are economically-important fish exploited extensively by artisanal fisheries on the Amazon coast of Brazil. In the present study, 150 specimens of redeye mullet (Mugil rubrioculus) acquired from the public fish market were examined, and the gill filaments of 90 (60%) were found to be infected with spores of Myxobolus. The mature spores were spherical, with a mean diameter of 6.28±0.33 μm, and had polar capsules of equal size (2.47±0.34 μm in length and 1.58±0.27 μm in width). The 18S rRNA sequence of the parasite was compared with those of other myxosporidian species available in the GenBank database. The morphological and molecular characteristics of the parasite indicate strongly the existence of a new species, denominated Myxobolus bragantinus n. sp., the first case of a new myxosporidian species to be found in this host.

Abstract:
Die Arbeit verfolgt das Ziel, eine Übersicht über die bei verschiedenen Süßwasserfischarten festgestellten Myxosporidien zu geben. Aus Gewässern der DDR-Bezirke Potsdam, Berlin, Frankfurt (Oder), Cottbus und Dresden wurden 1.850 Fische (1.015 Karpfen, 258 Regenbogenforellen, 143 Silberkarpfen, 104 Plötzen sowie weitere 22 Fischarten in geringer Zahl untersucht. Es wurden 40 Myxosporidienarten folgender taxonomischer Gruppen nachgewiesen: Myxidiidae (7), Sphaerosporidae (6), Chloromyxidae (4) und Myxobolidae (23). In der Arbeit sind Maße, Fotos und Zeichnungen der Parasiten enthalten. Es wurden Angaben über die Taxonomie, Organspezifität, Saisondynamik, Epizootiologie und Auswirkungen auf die Fischgesundheit gemacht. Es erfolgte ein Vergleich mit früheren Arbeiten in der DDR auf diesem Gebiet. Der Artenbestand an Myxosporidien konnte um 39 Arten erweitert werden. Anhand faunistischer Arbeiten aus benachbarten Ländern wurden die Bedeutung und Perspektiven zum Auftreten von Myxosporidiosen in der DDR herausgestellt.
This work aims to give an overview about the detected Myxosporeans in different species of freshwater fishes. From inland waters of the GDR districts Potsdam, Berlin, Frankfurt (Oder), Cottbus and Dresden 1.850 fishes (1.015 carps, 258 rainbow trouts, 143 silver carps, 104 roach and more 22 Fish species in small numbers were studied. 40 Myxosporean species of following taxonomic groups were detected: Myxidiidae (7), Sphaerosporidae (6), Chloromyxidae (4) und Myxobolidae (23). In this work are presented dimensions, photos and drawings of the parasites. Details are given on taxonomy, organ specificity, season dynamics, epizootiology and the impact on fish health A comparison with previous work in the GDR on this subject was carried out. The species inventory on Myxosporidia could be extended to 39 species. Based on faunal work from neighboring countries the importance and prospects for occurrence of Myxosporidiosis in the GDR were highlighted.

Abstract:
Cette etude porte sur les myxosporidies parasites des muges de mediterranee occidentale principalement mugil cephalus et liza ramada provenant du lac ichkeul de tunisie. Les donnees ultrastructurales ont permis de differencier 7 especes du genre myxobolus dont trois nouvelles m. Bizerti n. Sp. ; m. Ichkeulensis n. Sp. ; m. Ramadae n. Sp. , formant des kystes branchiaux. Trois formes viscerales ont ete identifiees: m. Spinacurvatura ; m. Mulleri, localisees dans les vaisseaux mesenteriques et m. Exiguus infestant la paroi intestinale. La 7eme espece recoltee au niveau du tegument a ete rattachee a m. Espisquamalis, responsable du rejet commercial des poissons atteints. Les caracteres ultrastructuraux des kystes et des stages sporogoniques ont ete decrits. Leur action pathologique a ete examinee. L'incidence sur l'embonpoint de leurs hotes ainsi que le facteur de risque d'infestation de ces parasites lie a la taille de l'hote ont ete analyses. L'obtention d'une sonde anticorps polyclonale anti-myxobolus episquamalis, a permis de realiser une etude antigenique de ce parasite, de determiner des antigenes specifiques, d'autres communs a plusieurs especes de myxosporidies etudiees et de demontrer une parente antigenique entre myxobolus episquamalis et son hote mugil cephalus

L'etude de la parasitofaune des poissons marins mediterraneens des cotes francaises du languedoc-roussillon et de la baie de kotor (adriatique) en yougoslavie, a revele la presence de 45 especes de myxosporidies, dont huit nouvelles pour la science. Plusieurs aspects de la biologie de ces parasites sont abordes. L'impact de ces parasites en aquaculture a ete etudie a travers le modele thelohanellus nikolskii responsable d'epizooties dans les elevages de carpes d'europe centrale et d'asie. La pathologie liee a cette espece, ainsi que les stades initiaux de la sporogenese ont ete precises. Les affinites des myxosporidies avec le parasite pkx et les marteilia nous a amene a etudier egalement le cas de ces deux autres parasitoses: l'hepatonephrite parasitaire des salmonides (pkd), ainsi que la marteiliose de l'huitre plate ostrea edulis. Les premieres approches moleculaires de ces organismes ont permis la construction d'une banque genomique de m. Refringens et la caracterisation d'une premiere sonde nucleique specifique. L'etude preliminaire de celle-ci a ete realisee, et son utilisation comme outil epidemiologique et de diagnostic, est abordee

Todos os indivíduos amostrados encontravam-se parasitados. Dezenove espécies de parasitos foram identificadas, sendo sete cestodas proteocefalídeos, três monogeneas, um digenea, três nematodas, um acantocéfalo, um crustáceo, um pentastomídeo e duas espécies de mixosporídeos. As espécies de cestóides, Harriscolex kaparari e Megathylacus travassosi são registradas pela primeira vez para P. fasciatum capturados no rio Aquidauana. Os monogeneas foram os endohelmintos que apresentaram maior prevalência (100 %), seguidos pelos cestodas (91,18 %) e nematodas (58,82 %).
