CK-2 of rainbow trout (Oncorhynchus mykiss) has two differentially regulated alleles that encode a functional chemokine
Semple, Shawna L.; Eshaque, Shathi; Fujiki, Kazuhiro; Tang, Cynthia; Mitchell, Leslie; Bols, Niels C.; Dixon, Brian (Elsevier, 2018-04)Rainbow trout chemokine 2 (CK-2) is currently the only known CC chemokine to have a mucin stalk. Further analysis of the mucin stalk region revealed a second, related CC chemokine sequence, denoted here as CK-2.1. This ... -
Extracellular dsRNA induces a type I interferon response mediated via class A scavenger receptors in a novel Chinook salmon derived spleen cell line
Semple, Shawna L.; Vo, Nguyen T. K.; Poynter, Sarah J.; Li, M.; Heath, Daniel D.; DeWitte-Orr, Stephanie J.; Dixon, Brian (Elsevier, 2018-12-01)Despite increased global interest in Chinook salmon aquaculture, little is known of their viral immune defenses. This study describes the establishment and characterization of a continuous cell line derived from Chinook ... -
Improving Aquaculture: the Impact of Bacterial Disease Treatments on Salmonid Immune Performance
Semple, Shawna L. (University of Waterloo, 2019-12-13)Aquaculture is a global multibillion-dollar industry that is continuously threatened by infectious diseases, including those of bacterial origin. Currently, the only method to combat bacterial disease outbreaks as they ... -
Long-term implantation of acoustic transmitters induces chronic inflammatory cytokine expression in adult rainbow trout (Oncorhynchus mykiss)
Semple, Shawna L.; Mulder, Ingeborg M.; Rodriguez-Ramos, Tania; Power, Michael; Dixon, Brian (Elsevier, 2018-11-01)Telemetry transmitters are frequently used in studies of wild fish migration and behavior. Although the effects of surgically implanted transmitters on survival, tag retention, healing and growth have been studied, there ... -
Serum IgM, MH class IIβ genotype and respiratory burst activity do not differ between rainbow trout families displaying resistance or susceptibility to the coldwater pathogen, Flavobacterium psychrophilum
Semple, Shawna L.; Kellendonk, Calvin J.; Al-Hussinee, Lowia; MacInnes, Janet I.; Lumsden, John S.; Dixon, Brian (Elsevier, 2018-01-20)Flavobacterium psychrophilum, the causative agent of bacterial coldwater disease (BCWD) is a significant threat to global aquaculture. True to its name, BCWD tends to occur at temperatures between 8 and 12°C and presents ...
