Three new Diplozoidae mitogenomes expose unusual compositional biases within the Monogenea class: implications for phylogenetic studies [PDF]

open access: yesBMC Evolutionary Biology, 2018
Background As the topologies produced by previous molecular and morphological studies were contradictory and unstable (polytomy), evolutionary relationships within the Diplozoidae family and the Monogenea class (controversial relationships among the ...

The Ultrastructure of the Gastrodermis and the Nutrition of the Gill Parasitic Atriaster heterodus Lebedev and Paruchin, 1969 (Platyhelminthes: Monogenea)

open access: yesMemorias do Instituto Oswaldo Cruz, 1998
The gastrodermis of Atriaster heterodus Lebedev & Paruchin, 1969 (Polyopisthocotylea), a gill parasite from Diplodus argenteus (Valenciennes, 1830), is composed of "U"-shape hematin cells and a connecting syncytium, both having cytoplasmic lamellae ...

Ultrastructure of spermiogenesis, spermatozoa and the tegument in Atriaster sp. (Platyhelminthes, Monogenea, Polyopisthocotylea, Microcotylidae)

open access: yesZoologica Scripta, 1992
Atriaster (Atriaster) sp., a gill parasite in the fish Diplodus cervinus caught near Dakar, Senegal, was studied by transmission electron microscopy. Spermiogenesis is similar to the general scheme in the Cercomeridae and particularly the polyopisthocotylean monogeneans, but shows two remarkable characteristics: (a) the zone of differentiation for ...

Light and electron microscopy of Paranella diplodae N. SP. (Polyopisthocotylea;Microcotylidae; Monogenea ) from some Red Sea Teleost fishes in Egypt

open access: yesJournal of Veterinary Medical Research, 2007
The present study deals with a monogenean parasite infecting, some marine fish through light and scan electron microscopy. It revealed that the percentage of infection was 48% (14 out of 50 fish), 28% (14 out of 50 fish), 22% (11 out of 50 fish) and 16% (

Four polyopisthocotyleans (Platyhelminthes: Monogenea) from carangid fishes in the Mediterranean, off the Algerian coasts

open access: yesCurrent Research in Parasitology and Vector-Borne Diseases, 2021
Four polyopisthocotyleans were collected from the gill filaments of carangids from off the Algerian coast, southern Mediterranean. Specimens of Gastrocotyle trachuri van Beneden & Hesse, 1863 (Gastrocotylidae) and Cemocotyle cf. trachuri Dillon &

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 ...

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.

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,
