Phylogénie des monogènes basée sur une analyse de parcimonie des caractères de l'ultrastructure de la spermiogenèse et des spermatozoïdes incluant les résultats récents

open access: yesKnowledge and Management of Aquatic Ecosystems, 1993
Les caractères de la spermiogenèse et du spermatozoïde ont été utilisés pour une analyse de parcimonie des Monogènes avec le programme PAUP. Les données utilisées comprennent la matrice proposée dans une analyse précédente (JUSTINE, 1991, Int.

Neobenedenia melleni Parasite of Red Snapper, Lutjanus erythropterus, with Regression Statistical Analysis between Fish Length, Temperature, and Parasitic Intensity in Infected Fish, Cultured at Jerejak Island, Penang, Malaysia

open access: yesJournal of Parasitology Research, Volume 2016, Issue 1, 2016., 2016
The fish parasites collected from Lutjanus erythropterus fish species showed a correlation with parasitic intensity, fish size, and temperature, and statistical model summary was produced using SPSS version 20, statistical software. Statistical model summary concluded that among the variables which significantly predict the prevalence of Neobenedenia ...

Experimental transmission of Sparicotyle chrysophrii (Monogenea: Polyopisthocotylea) to gilthead seabream (Sparus aurata) and histopathology of the infection [PDF]

open access: yesFolia Parasitologica, 2009
The polyopisthocotylean Sparicotyle chrysophrii (Van Beneden et Hesse, 1863) was experimentally transmitted to gilthead seabream (Sparus aurata L.) by exposure to eggs (EGT) and by cohabitation with naturally parasitized fish (CT). In EGT trials, the infection was successfully transmitted by introducing containers with monogenean eggs in the fish tanks,

Hypothèse sur l’origine biogéographique deDiplozoon(Monogenea, Polyopisthocotylea) [PDF]

open access: yesAnnales de Parasitologie Humaine et Comparée, 1988
SUMMARY. The evolutionary geographic origin of Diplozoon and Octomacrum (Monogenea, Polyopisthocotylea) is discussed. Diplozoon occurs in Eurasia and Africa, whereas the distribution of Octomacrum is limited to North-America. These two monogeneans likely had a common proge­ nitor originating from the Pacific.

New records of nine monogenean parasites infesting non‐native freshwater fish species in New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1052-1068, December 2025.
ABSTRACT Twenty‐one non‐native freshwater fish species have established populations in New Zealand, yet only two have been reported with monogenean infestations; grass carp, Ctenopharyngodon idella (Valenciennes in Cuvier and Valenciennes, 1844) and western mosquitofish, Gambusia affinis (Baird and Girard, 1853), each with two identified monogenean ...

Observations on the food and the gut pigment of the Polyopisthocotylea (Trematoda: Monogenea)

open access: yesParasitology, 1954
1. It has been shown by spectroscopic and histochemical methods that eight representative species of Polyopisthocotylea feed mainly on the blood of their hosts.2. The blood is probably haemolysed fairly rapidly and subsequently absorbed by amoeboid ingestion, the globin moiety of the haemoglobin forming the chief nutriment of the parasite and the ...

First Report of Calceostoma glandulosum (Monogenea) in Argyrosomus regius: Morphological and Molecular Characterization and Temperature Effects on Life Cycle

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
The increase in fish production in aquaculture reflects the growth of the world population. However, this expansion is accompanied by challenges, such as the intensification of production systems through increased stocking density, which induces stress in fish, weakening their immune system and making them more susceptible to disease outbreaks ...

Monogenean Sparicotyle chrysophrii: The major pathogen of the Mediterranean gilthead seabream aquaculture

open access: yesReviews in Aquaculture, Volume 16, Issue 1, Page 287-308, January 2024.
Sparicotylosis has been present in Mediterranean aquaculture of the gilthead seabream for the past 25 years, yet disease management and treatments are not effective. This is further jeopardised by global warming and resistance of Sparicotyle chrysophrii to available anthelminthic compounds.
