Physiology and immunology of Lepeophtheirus salmonis infections of salmonids
Trends in Parasitology, 2008'Sea lice' is a common name for a large number of species of marine ectoparasitic copepods, many of which are widespread and important disease-causing agents that infect both cultured and wild fish. Of these copepods, the salmon louse Lepeophtheirus salmonis is the most extensively studied because of its economic impact on the salmonid aquaculture ...

New replacement name for a homonym in Lepeophtheirus (Crustacea: Copepoda: Caligidae)
Zootaxa, 2020Markevich (1940) established Pseudolepeophtheirus Markevich, 1940 for Pseudolepeophtheirus longicauda Markevich, 1940 based on copepods collected from the pleuronectid fish Platichthys stellatus (Pallas, 1787). Dojiri & Ho (2013) synonymized the genus and the species with Lepeophtheirus Nordmann, 1832 and Lepeophtheirus parvicruris Fraser, 1920 ...

Modulation of cellular innate immunity by Lepeophtheirus salmonis secretory products
Fish & Shellfish Immunology, 2014Lepeophtheirus salmonis produces pharmacologically active substances that have been shown to modify genetic expression of inflammatory mediators in SHK-1 cells and head kidney macrophages of salmon. Differences in genetic expression among genera of Oncorhynchus and Salmo reflect different susceptibilities to L. salmonis.

Monooxygenase mediated pyrethroid detoxification in sea lice (Lepeophtheirus salmonis)
Pest Management Science, 2005AbstractThe role of monooxygenases in detoxification of the pyrethroids cypermethrin and deltamethrin was examined. Four strains of sea lice (Lepeophtheirus salmonis Krøyer) with normal or moderately reduced sensitivity towards the pyrethroids were tested in bioassays by exposure to the pyrethroid alone and in combination with an oxygenase inhibitor ...

Cholinergic activity in different stages of sealice (Lepeophtheirus salmonis)
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989Abstract 1. 1. All stages of sealice, from mature egg to adult, had choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) activity, indicating cholinergic nervous activity. 2. 2. This means that the insensitivity in the early stages of the sealouse against treatment with organophosphates cannot be explained by the lack of ...

Anti-chemotactic activity in the secretory/excretory products of Lepeophtheirus salmonis
Fish & Shellfish Immunology, 2020The ectoparasite, Lepeophtheirus salmonis (Kroyer 1837), is effective at avoiding elimination from its host, Atlantic salmon, Salmo salar L., by inhibiting the recruitment of immune cells to the site of attachment. In other ectoparasitic arthropods, numerous factors have been identified that bind or neutralize chemokines preventing their interaction ...

Life History of Lepeophtheirus salmonis
Journal of the Fisheries Research Board of Canada, 1942Heavy infestations of this copepod in various developmental stages occur on Salmo salar and Salvelinus fontinalis at Moser River, N.S. Males and females occur in about equal numbers. Metanauplius and chalimus stages were present on the fins of the hosts. The male and four of the developmental stages are described and figures given.
