|Title: New Fish Vaccine for Flavobacterium Columnare|
US Patent Office Full Record
ARS researchers have developed a new live vaccine that is safe and effective for the control of Flavobacterium columnare in catfish. F. columnare is an aquatic bacterium that infects channel catfish, sport fish such as perch, walleye, pike, centrachids (bass and sunfish), aquarium fish and baitfish. Columnaris is the second leading cause of mortality in pond raised catfish in the southeastern
Medicated feed with several chemotherapeutics currently used to control the disease have limited effect and are not approved for use on food fish. Most producers have discontinued use of medicated feeds. The vaccine, which can be given by injection or by immersion, is effective in providing long lasting acquired immunity in channel catfish to F. columnare.
Companies that make vaccines for aquaculture could use this technology. Developing a Flavobacterium columnare vaccine could potentially save aquaculture producers money by preventing this disease.
