Identification and partial characterization of a novel serpin from Eudiplozoon nipponicum (Monogenea, Polyopisthocotylea) [PDF]

Parasite, 2018
Background: Serpins are a superfamily of serine peptidase inhibitors that participate in the regulation of many physiological and cell peptidase-mediated processes in all organisms (e.g.

Morphological identification tools of Pseudodiscocotyla opakapaka and Kannaphallus raphidium (Monogenea: Polyopisthocotylea) from Acanthopagrus bifasciatus (Spariformes: Sparidae) [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Fish is considered one of the nutritive protein sources affected by various parameters including parasitism. Monogeneans are an ectoparasitic species infecting fish’s skin, fins, and gills.

First record of Amphipolycotyle chloroscombrus Hargis, 1957 (Monogenea, Polyopisthocotylea, Gastrocotylidae) in the South Atlantic Ocean [PDF]

Brazilian Journal of Oceanography, 2016
Monogeneans are a group of largely ectoparasitic members of the phylum Platyhelminthes. These worms are considered to be among the most host-specific parasites in fish, commonly found on fins, body skin, gills, gill chambers, buccal cavity, cornea and nostrils of their host (BUCHMANN et al., 2004).

Spermiogenesis and spermatozoon ultrastructure in basal polyopisthocotylean monogeneans, Hexabothriidae and Chimaericolidae, and their significance for the phylogeny of the Monogenea [PDF]

Parasite, 2018
Sperm ultrastructure provides morphological characters useful for understanding phylogeny; no study was available for two basal branches of the Polyopisthocotylea, the Chimaericolidea and Diclybothriidea.

Ultrastructure of spermiogenesis and spermatozoa of Discocotyle sagittata (Monogenea: Polyopisthocotylea: Discocotylinea) [PDF]

Folia Parasitologica, 2001
Ultrastructural analysis revealed that the spermatozoon of Discocotyle sagittata (Leuckart, 1842) is composed of two parallel axonemes, mitochondrion, nucleus and cortical microtubules. The nucleus, which occupies a central/distal position and has an unusual crescent-shaped profile, is slightly shorter than the mitochondrial rod.

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

Knowledge 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.

Chaetotaxy of members of the Gyrodactylidae (Monogenea), with comments upon their systematic relationships with the Monopisthocotylea and Polyopisthocotylea

Systematic Parasitology, 1998
This study investigates intra- and inter-generic variation in the chaetotaxy pattern of members of the Gyrodactylidae and compares these data with those from other monogenean groups elucidated by other workers. The staining of surface sensillary structures has revealed areas of homology between the two genera Gyrodactylus and Ooegyrodactylus, which ...

“Something old, something new, something borrowed, and the oioxeny is true”: description of Plectanocotyle jeanloujustinei n. sp. (Polyopisthocotylea, Plectanocotylidae) from the MNHN Helminthology collection with novel molecular and morphological data for P. gurnardi (Van Beneden & Hesse, 1863) (sensu stricto) from Sweden

International Journal for Parasitology: Parasites and Wildlife
Natural history museums worldwide house billions of apposite specimens, offering the potential for cost-free parasitological datasets. Herein, we provide novel morphological and molecular data (28S and cox1) for the polyopisthocotylean Plectanocotyle ...

Laser capture microdissection in combination with mass spectrometry: Approach to characterization of tissue-specific proteomes of Eudiplozoon nipponicum (Monogenea, Polyopisthocotylea).

PLoS ONE, 2020
Eudiplozoon nipponicum (Goto, 1891) is a hematophagous monogenean ectoparasite which inhabits the gills of the common carp (Cyprinus carpio). Heavy infestation can lead to anemia and in conjunction with secondary bacterial infections cause poor health ...

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

Memorias 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 ...
