Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Exploring Silver as an Alternative Treatment for Controlling Macrogyrodactylus congolensis Populations

Aquaculture Research, Volume 2025, Issue 1, 2025.
Monogeneans are ectoparasites that in high densities, can cause harm and even death to their hosts. Therefore, treatment methods are continuously evaluated. The current study aims to determine the LC50 of ionic silver and silver‐engineered nanomaterials (ENMs) (nAg) in the monogenean Macrogyrodactylus congolensis and report on the toxicological effects

Mechanism of adhesion and detachment at the anterior end of Merizocotyle icopae (Monogenea: Monocotylidae) including ultrastructure of the anterior adhesive matrix [PDF]

, 2004
The anterior adhesive mechanism was studied for Merizocotyle icopae (Monogenea: Monocotylidae). Adult anterior apertures can open and close. In addition, duct endings terminating within the apertures are everted or retracted depending on the stage of ...

First Report of Calceostoma glandulosum (Monogenea) in Argyrosomus regius: Morphological and Molecular Characterization and Temperature Effects on Life Cycle

Aquaculture Research, Volume 2025, Issue 1, 2025.
The increase in fish production in aquaculture reflects the growth of the world population. However, this expansion is accompanied by challenges, such as the intensification of production systems through increased stocking density, which induces stress in fish, weakening their immune system and making them more susceptible to disease outbreaks ...

Killing of Gyrodactylus salaris by heat and chemical disinfection [PDF]

, 2015
BACKGROUND: Gyrodactylus salaris is a monogenean, which has collapsed tens of wild Atlantic salmon populations. One of the means of preventing the spread of the parasite is the disinfection of the fishing equipment, which is used in the rivers having ...

The phylogenetic position of the enigmatic Balkan Aulopyge huegelii (Teleostei: Cyprinidae) from the perspective of host-specific Dactylogyrus parasites (Monogenea), with a description of Dactylogyrus omenti n. sp.

Parasites & Vectors, 2017
BackgroundThe host specificity of fish parasites is considered a useful parasite characteristic with respect to understanding the biogeography of their fish hosts.
