A major allergen in rainbow trout (Oncorhynchus mykiss): complete sequences of parvalbumin by MALDI tandem mass spectrometry.

A putative serine protease, SpSsp1, from Saprolegnia parasitica is recognised by sera of rainbow trout, Oncorhynchus mykiss

Saprolegniosis, the disease caused by Saprolegnia sp., results in considerable economic losses in aquaculture. Current control methods are inadequate, as they are either largely ineffective or present environmental and fish health concerns. Vaccination of fish presents an attractive alternative to these control methods. Therefore we set out to identify suitable antigens that could help generate...

Parvalbumin expression in trout swimming muscle correlates with relaxation rate.

Rainbow trout (Oncorhynchus mykiss) display longitudinal and developmental shifts in muscle relaxation rate. This study aimed to determine the role of variations in parvalbumin content in modulating muscle relaxation. Parvalbumin is a low molecular weight protein that buffers myoplasmic Ca2+ and enhances muscle relaxation. In some fish, longitudinal variations in muscle relaxation have been lin...

The influence of Wisconsinan glaciation and contemporary stream hydrology on microsatellite DNA variation in rainbow trout (Oncorhynchus mykiss)

Microsatellite DNA variation was examined in rainbow trout (Oncorhynchus mykiss) populations from throughout British Columbia, Canada, to address the roles of historical isolation, postglacial dispersal, and contemporary geomorphology in structuring genetic variation and differentiation. We detected signatures of historical isolation and postglacial recolonization in the form of ‘‘interior’’ an...

A Comparision on FCR in fish ponds of Rainbow Trout (Oncorhynchus mykiss) fed by extruder food and pellete food

Cloning and sequencing of rainbow trout (Oncorhynchus mykiss) interferon regulatory factor 7

  Interferon regulatory factor 7 (IRF7) gene was cloned from a subtractive cDNA library constructed with mRNAs obtained from rainbow trout (Oncorhynchus mykiss) macrophage cell line (RTS-11). Using expressed sequence tag clones of submitted IRF7 amino acid sequences, specific primers were designed. Results showed that IRF7 cDNA contains an ORF of 1251 nucleotides that translates into a 416 resi...
