effect of milk thistle plant, vitis vinifera extract on immune system of rainbow trout (oncorhynchus mykiss) challenge by diazinon

Effects of Sewage Treatment Plant Effluent on the Immune System of Rainbow Trout (Oncorhynchus mykiss)

Rainbow Trout, Oncorhynchus mykiss

Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...

The effects of safflower (Carthamus tinctorius) ethanolic extract on non-specific immune system of rainbow trout (Oncorhynchus mykiss).

In the present study, the effect of the intraperitoneal injection of Carthamus tinctorius extract on non-specific immune system and some serological of Oncorhynchus mykiss has been investigated. To this end, the fish with average weight of 100±10 gr were intraperitoneally injected by different levels of safflower extract. In this regard, a negative control group (no injection), a positive contr...

Effect of the mycotoxin deoxynivalenol on the immune responses of rainbow trout (Oncorhynchus mykiss)

The trichothecene mycotoxin deoxynivalenol (DON) is commonly found as a natural contaminant in cereals such as wheat, barley, and corn, and exhibits various toxicological effects when present in animal feeds. The effects of DON at a nominal 2 mg/kg feed on immune responses of rainbow trout were investigated, including relative gene expression of important cytokines (TNF-α, IL-8, IL-1β, IL-10), ...

Modulation of rainbow trout (Oncorhynchus mykiss) intestinal immune gene expression following bacterial challenge.

The mucosal immune systems of fishes are still poorly understood, and defined models for studying natural host-pathogen interactions are lacking. The objective of this study was to evaluate different challenge models and pathogens to examine the magnitude of change in intestinal immune gene expression. Rainbow trout were exposed by immersion to Yersinia ruckeri or by intraperitoneal injection w...

Effects of dietary selenomethionine on larval rainbow trout (Oncorhynchus mykiss).

Increased selenium (Se) concentrations in water (>10 microg/L) have been measured in the San Diego Creek, which is a tributary of the Upper Newport Bay in Orange County, CA. The objective of this study was to develop tissue- and dietary-based thresholds for Se in resident fish species in San Diego Creek. A 90-day dietary experiment was conducted to determine the effects of seleno-L-methionine (...
