Efficacy of a modified live Flavobacterium columnare vaccine in fish

Catfish hybrid Ictalurus punctatus × I. furcatus exhibits higher resistance to columnaris disease than the parental species

“…Previous studies have shown that ARS-1 can cause up to 46% mortality in channel catfish fry (Shoemaker et al 2008), but < 40% in channel fingerlings (Shoemaker et al 2011). …”

Concurrent infections of Flavobacterium columnare and Edwardsiella ictaluri in striped catfish, Pangasianodon hypophthalmus in Thailand

“…Early management strategies to control the spreading of E. ictaluri and F. columnare, in a sustainable intensively cultured system in Thailand, therefore, are highly recommended. As a model lesson, disease manipulation strategy against infectious pathogens using monovalent or bivalent vaccine has been developed as a priority and widely applied to fish farms in the United States (Klesius and Shoemaker, 1999;Shoemaker et al, 2007Shoemaker et al, , 2011. Our further study will focus on the development of a combined vaccine against coinfection of E. ictaluri and F. columnare in striped catfish.…”

A Review of Molecular Responses of Catfish to Bacterial Diseases and Abiotic Stresses

“…In extreme conditions, the mortality for channel catfish fries after columnaris infection can reach up to 90%. The mortality rate for pond raised channel catfish can also reach as high as 50–60% (Decostere et al, 1998; Morley and Lewis, 2010; Plumb and Hanson, 2011), causing annual economic loss of approximately $30 million for the U.S. catfish industry (Shoemaker et al, 2011). …”
