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.

Host factors limiting monogenean infections: a case study
International Journal for Parasitology, 2002Comprehensive field data on polystomatid monogeneans record low prevalence and intensity of infection and suggest that worm burdens in this group are strongly regulated: thus, in the majority of Polystoma species infecting anuran amphibians mean abundance is typically less than one parasite/host.

Interactions between monogenean parasites and their fish hosts
International Journal for Parasitology, 2002Parasite factors associated with recognition and selection of the host and the mechanisms in the host responsible for acceptance or rejection of the invading organism were evaluated. Sensory structures in parasites are able to detect differences between different fish species and this ability to discern between fishes may be based on both chemical and ...

Insemination of the monogenean Neobenedenia girellae (Capsalidae, Benedeniinae)
Parasitology International, 2014In vitro spermatophore formation and insemination of Neobenedenia girellae (Monogenea: Capsalidae, Benedeniinae) were recorded on video and described for the first time. Upon contact of two individuals, the anterior adhesive discs of the donor firmly attached to the dorsal tegument of the recipient and the donor's fore body strongly contracted such ...

New technique for collecting eggs from monogenean parasites
Experimental Parasitology, 2013A novel and easily constructed apparatus for collecting monogenean eggs released by the parasites into the water is described and illustrated. Use of this technique may lead to a better understanding of the parasite's biology, which, in turn, may lead to the improvement of parasite management strategies in fish farms where monogeneans are potentially ...

Transmission of the monogenean Gyrodactylus salaris
Parasitology International, 1998The present study is focusing on the transmission of the monogenean ectoparasite Gyrodactylus salaris Malmberg, 1957, a major pathogen on natural populations of Norwegian Atlantic salmon, Salmo salar L. In laboratory experiments the transmission rate of G.

Non-monophyly of the monogeneans?
International Journal for Parasitology, 1998There is currently no congruence between phylogenies based on morphology, in which the Monogenea are considered a monophylum, and molecular phylogenies based on 18S or 28S rDNA, in which the Monogenea are never considered monophyletic. However, all analyses based on morphology and sperm characters or molecular data found constantly the two subgroups ...

Monogenean fauna of District Saharanpur UP Part -Ii
2004Present communication deals with one new and one known species of the genusParadactylogyrus Thapar (1948) and Bifurcohaptor Jain (1958) from freshwater fishes Labeorohita (Ham.) and Mystus vittatus (Bloch). The new species is characterized on the basis ofdifference in shape of copulatory complex, and haptoral armature, etc.
