Introduction. Dactylogyrus (common name: Gill Fluke) are oviparous (egg-laying) monogeneans trematodes that have two pairs of anchors. These anchors can be used to latch onto the gills of a host, particularly freshwater fish such as carp. In heavily infected fish, Dactylogyrus can also be found on the buccal cavity, and at times fins and skin of the freshwater : Monogenea.

Introduction. Fishes are important to man as a good source of protein in man’s diet and as a vector of some human disease pathogens. The common carp, Cyprinus carpio, is apparently the most widely geographically distributed fish species in Iran and other region of world.

Owing to its adaptation to a wide range of climatic and geographical conditions, a substantial number of Cited by: Introduction. The parasites of the Dactylogyrus species are monogenean trematodes of the family Dactylogyridae.

Members of the Dactylogyrus species prefer to live on the gills of host fish, most often cultured Cyprinids (common carp, grass carp, silver carp). The adults are oviparous and the eggs are released into the water to hatch. These eggs are often very resistant and can survive.

The taxonomy of Dactylogyrus Diesing, (Monogenea: Dactylogyridae), like that of most monopisthocotyleans, relies heavily on the morphology of sclerites of the posterior attachment organ (haptor). However, the associated neuromusculature is essentially unknown and, therefore, the aim of this study was to use confocal microscopy to examine the haptoral Cited by: 4.

Dactylonectria macrodidyma (Halleen, Schroers & Crous) L. Lombard & Crous, Phytopathologia Mediterranea 53 (3): () [MB#]. This article reviews the history of gyrodactylid research focussing on the unique anatomy, behaviour, ecology and evolution of the viviparous forms while identifying gaps in our knowledge and directions for future research.

We provide the first summary of research on the oviparous gyrodactylids from South American catfish, and highlight the plesiomorphic characters shared. Early studies (Olsen, ) suggested that as theropod tracks in the Grallator-Eubrontes plexus increase in size, they shift from narrow to wide and from strongly to weakly mesaxonic.

However, such polarities also reiterate (independent of size) among medium-sized and diminutive theropod tracks (e.g., Minisauripus). Double dactyls, a light-verse form consisting of eight lines of two dactyls each, arranged in two stanzas.

pages each, good Range: $ - $ Taxonomies have always been fluid and contentious, in part because of a paucity of data, and in part because of the inherently subjective nature of classification decisions. Many biologists, including ourselves, firmly believe that taxonomy should be based upon evolutionary history (phylogeny) whenever possible.

Dactylogyrids were isolated from 12 siluriform species, belonging to six families (Bagridae, Clariidae, Claroteidae, Malapteruridae, Mochokidae and Schilbeidae). Dactylogyrid species of the following genera were found: Bagrobdella, Protoancylodiscoides, Quadriacanthus, Schilbetrema and : Kateřina Francová, Mária Seifertová, Eva Řehulková.
