Gill monogeneans of neotropical cichlid fish: diversity, phylogenetic relationships, and host-parasite cophylogenetic associations.

International Journal of Parasitology, 2022
Host-parasite coevolution is one of the main topics of the evolutionary biology of host-parasite associations. The majority of monogeneans parasitizing fish exhibit a high degree of host specificity.

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 ...

Diversity of monogeneans and tapeworms in cypriniform fishes across two continents.

International Journal of Parasitology, 2020
Cypriniformes, which exhibit a wide geographical distribution, are the most species-rich group of freshwater fishes. Despite considerable research on their parasites, no reliable estimates of their parasite diversity on a large geographical scale are ...

Efficacy of geraniol and ß-citronellol against freshwater and marine monogeneans.

Journal of Aquatic Animal Health, 2020
Monogeneans are parasitic flatworms that may be a threat for finfish aquaculture. In this study, the anthelminthic activity of two terpenes, geraniol and β-citronellol, was tested in vitro against ancyrocephalin and diplectanid monogeneans.

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.

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.

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.

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 (

Chitin modulates immunity and resistance of Labeo rohita (Hamilton, 1822) against gill monogeneans

Aquaculture, 2019
The present study was conducted to delineate the effects of dietary chitin on the immune status and resistance of rohu (Labeo rohita) against gill monogeneans. The study consisted of two experimental trials.

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.
