Exposure to metals and other trace elements negatively affects infection dynamics of monogeneans, including diplozoids, but, physiological mechanisms linked to exposure have yet to be documented. In this study sequestration of trace elements and reactive oxygen intermediate production in the monogenean, Paradiplozoon ichthyoxanthon, was demonstrated. During dissection of host fish, Labeobarbus ...

Fish monogeneans are lethal parasites in aquaculture. We provide the first experimental evidence that a notorious fish monogenean, Neobenedenia sp., can produce viable eggs in isolation for three consecutive generations. We infected individual, isolated, farmed barramundi, Lates calcarifer (Bloch) with a single oncomiracidium (larva) of the hermaphroditic monogenean Neobenedenia sp.. Isolated p...

BACKGROUND Infection incidence increases with the average number of contacts between susceptible and infected individuals. Contact rates are normally assumed to increase linearly with host density. However, social species seek out each other at low density and saturate their contact rates at high densities. Although predicting epidemic behaviour requires knowing how contact rates scale with hos...

The representatives of the class Monogenea are great importance in fish pathology. Dactylogyrus vastator (Nybelin 1924) (Monogenea: Dactylogyridae) is a common pathogenic monogenean parasite carp (Cyprinus carpio Linnaeus, 1758) from freshwater lakes and cyprinid ponds, worldwide. In our study, total 133 specimens cage culture system on Mladost Reservoir (N. Macedonia) were subjected to parasit...

Mozambique tilapia Oreochromis mossambicus (Peters, 1852), an important aquaculture species investigated herein, is at risk and listed as vulnerable on the IUCN Red List. During a preliminary survey conducted in 2011, 30 from Lake Urema Gorongosa National Park central Mozambique, were examined for metazoan parasites. Two groups of ectoparasites recovered consisting two copepods monogenean. Endo...

DNA taxonomy and barcoding use nucleotide sequence data to achieve comprehensive species descriptions that facilitate reliable species diagnostics and rapid assessment of biodiversity, both of which are of great importance for parasitologists. Such molecular approaches have been applied to the monogenean genus Gyrodactylus, in particular to G. salaris, the cause of serious gyrodactylosis on Atl...

The present study describes the molecular phylogenetic analysis of Dactylogyroides longicirrus (Monogenea: Dactylogyridae) infecting the gill filaments of fish Puntius sophore from the site Guwahati, Assam, India. The parasite Dactylogyroides longicirrus (Tripathi, 1959) Gusev, 1976 from Northeast Indian region is presented based on sequence data of a 738 base-pair fragment of ribosomal 18S sma...
