Pro-Inflammatory Properties Of Flavobacterium Columnare Cells And Products On Channel Catfish (Ictalurus Punctatus) Neutrophils, Shannon Billings

All Theses

Flavobacterium columnare and Edwardsiella ictaluri are the leading causes for losses in the aquaculture industry. The losses from the diseases caused by these pathogens total $2.5 million for catfish and $100 million for total aquaculture. F. columnare's infection rates and stressors associated with outbreaks have been well-characterized, but the specific inflammatory responses of catfish neutrophils to the bacteria have not been studied. The objective, therefore, was to investigate the pro-inflammatory effects of the outer membrane proteins, extracellular products, and whole live bacteria, heat-killed (HK), and formalin-killed (FK) F. columnare and E. ictaluri to determine the effects on channel catfish phagocyte …
