Phototactic responses in four monogenean oncomiracidia

Parasitology Research, 2021
Phototaxis is the common behavioral response exhibited by the oncomiracidia of various monogeneans. However, the changes in the oncomiracidial swimming behavior in response to light cues are not well understood. Here, we investigated the light responses of four monogeneans that are important pathogens in mariculture, namely Benedenia epinepheli ...

GyroDb: gyrodactylid monogeneans on the web

Trends in Parasitology, 2008
GyroDb (www.gyrodb.net) is a web-based resource that enables access to information on a key group of monogenean ectoparasites – the gyrodactylids. These small (

Spermatogenesis in a monogenean, Diclidophora merlangi

International Journal for Parasitology, 1976
Abstract Halton D. W. & Hardcastle A. 1976. Spermatogenesis in a monogenean, Diclidophora merlangi. International Journal for Parasitology 6: 43–53. Development of the spermatozoa in the testis of a polyopisthocotylean fish-gill fluke, Diclidophora merlangi , has been examined by light and electron microscopy.

The evolution of monogenean diversity

International Journal for Parasitology, 2002
The Monogenea are an ideal group for investigations of the processes behind their past diversification and their present diversity for at least three reasons: they are diverse both in terms of morphology and numbers, they are generally host specific, and their phylogeny is well resolved, at least to the family level.

Monogenean parasitic flatworms

Current Biology
Vanhove and colleagues introduce monogenean parasitic flatworms, a species-rich group of ectoparasitic flatworms that are mostly found on the skin, gills, or fins of fish and have a life cycle involving a single host.

Vitelline cell development in monogenean parasites

Zeitschrift f�r Parasitenkunde, 1974
Histochemical and electron microscopic studies of the vitellaria of three polyopisthocotylean fish-gill flukes,Diplozoon paradoxum, Diclidophora merlangi andD. denticulata, and one monopisthocotylean fish-skin fluke,Calicotyle kroyeri have shown that, in each case, vitelline cell development is basically similar.

THE MONOGENEAN PARASITES OF CANADIAN FRESHWATER FISHES

Canadian Journal of Zoology, 1967
A brief history of work performed on the Monogenea of Canadian freshwater fishes is recounted; a list indicating the host – monogenean parasite relationships of Canadian freshwater fishes is included. Dactylogyrus albertensis sp. nov., recovered from the gills of the flathead chub, Hyhopsis gracilis (Richardson), is described.

Diversity “down under”: monogeneans in the Antipodes (Australia) with a prediction of monogenean biodiversity worldwide

International Journal for Parasitology, 1998
There are approximately 25,000 species of fishes known in the world. The Monogenea are believed to be among the most host-specific of parasites and if each species of fish is host to a different species of monogenean, there could be almost 25,000 monogenean species on Earth.

Sperm transfer in monogenean (platyhelminth) parasites

Acta Parasitologica, 2015
AbstractThere are three major groups of parasitic platyhelminths (flatworms). The digeneans and cestodes are endoparasites, while the monogeneans are ectoparasites mostly on the gills or skin of fishes. Monogeneans are hermaphrodite and, with the exception of the gyrodactylids, mostly protandrous, the male reproductive system maturing before the female
