Kinetics of local and systemic immune cell responses in whirling disease infection and resistance in rainbow trout

Whirling disease (WD), caused by the myxozoan parasite Myxobolus cerebralis, is responsible for high mortalities in rainbow trout hatcheries and natural populations. To elucidate how resistant and susceptible rai...

Abstract Gene editing offers opportunities to solve fish farming sustainability issues that presently hampers expansion of the aquaculture industry. In for example Atlantic salmon farming, there are now two major bottlenecks limiting the expansion of the industry. One is the genetic impact of escaped farmed salmon on wild populations, which is considered the most long-term negative effect on the environment. Secondly and the utmost acute problem is the fish parasite salmon lice, which is currently causing high lethality in wild salmonids due to high concentrations of the parasite in the sea owing to sea cage salmo...

Lorenz, Rocio Crespo, Tatjana Iezhova, Gediminas Valkiūnas, Ravinder N.M. SehgalAbstractA juvenile White-headed woodpecker (Dryobates albolarvatus) fitted with a radio tag was located dead at approximately 22-days post-fledging in Yakima county in central Washington in July 2015. Postmortem examination revealed an enlarged liver and spleen plus evidence of iron sequestration. Microscopic examination observed young gametocytes within the cytoplasm of erythrocytes, and ex...

Madurro, Ana G.Brito-MadurroAbstractToxoplasma gondii is an intracellular protozoan parasite responsible for toxoplasmosis, which affects humans and animals. Serologic detection of anti-T. gondii immunoglobulins plays a crucial role in the clinical diagnosis of toxoplasmosis. In this work, a novel elect...

Detection of Gyrodactylus spp. is based on the morphological identification of isolated parasites after fish necropsy. Contributing to the diagnosis of gyrodactylosis, in this study, a non-destructive PCR assay was standardized; the PCR was first performed using genomic DNA of Gyrodactylus spp. isolated from the surface of the N...

Authors: Greber UF Abstract Virus particles, 'virions', range in size from nano-scale to micro-scale. They have many different shapes and are composed of proteins, sugars, nucleic acids, lipids, water and solutes. Virions are autonomous entities and affect all forms of life in a parasitic relationship. They infect prokaryotic and eukaryotic cells. The physical properties of virions are tuned to the way they interact with cells. When virions interact with cells, they gain huge complexity and give rise to an infected cell, also known as 'virus'. Virion-cell interactions entail the processes of entry, replication and ...

If the human bodies are infected with bacteria, fungi or parasites, the value of PCT in blood will be significantly raised. Thereby, we report an electrochemical immunosensor for measurement of PCT using gold nanoparticle (Au NP) decorated CeO2-CuO (CeO2-CuO-Au) as the platform and thionine modified Au@Ag heterojunction nanorods (Au@Ag-Th) as signal labels. Au NP decorated CeO2-CuO ...
