Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsia salmonis , the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.

First Report of the Malacosporean Parasite Tetracapsuloides bryosalmonae in the Faroe Islands Reveals Widespread Distribution and High Prevalence in Brown Trout

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT The myxozoan endoparasite Tetracapsuloides bryosalmonae (Tb), the causative agent of proliferative kidney disease (PKD) in salmonids, has predominantly been reported in temperate regions of continental Europe and North America. Here, we present the first record of Tb in the Faroe Islands, extending the known northern distribution of the ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

St John's Wort (Hypericum perforatum) Oil on Immune Response, Growth Performance and Bacterial Resistance Against Lactococcus garvieae Pathogen in Rainbow Trout (Oncorhynchus mykiss)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT In this study, we investigated the immunomodulatory effects of St. John's Wort (Hypericum perforatum) oil on the growth performance, immune responses and resistance against Lactococcus garvieae in rainbow trout (Oncorhynchus mykiss). The plant oil was incorporated into feeds at concentrations of 1, 3, and 5 g kg−1, designated as K1, K3, and K5,

Proliferative Kidney Disease and Viral Pathogens in Wild Brown Trout (Salmo trutta) Populations in the Czech Republic

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Populations of wild brown trout (Salmo trutta) have been in long‐term decline across Central Europe, including the Czech Republic, with multiple factors, such as habitat alteration, climate change, predation and emerging diseases, implicated.

Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsia salmonis is a well‐established intracellular pathogen of farmed Atlantic salmon around the world. The bacterium has also been detected from a number of other hosts including lumpfish (Cyclopterus lumpus), seabass (Dicentrarchus labrax) and rainbow trout (Oncorhynchus mykiss).

Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs

open access: yesJournal of Anatomy, EarlyView.
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.
