The Uses of Narasin from Streptomyces auriofaciens

Narasin is the main component of a polyether antibiotic complex produced by Streptomyces auriofaciens NRRL 5758 & NRRL 8092. Ionophoric antibiotic which inhibits coccidial infection in poultry and mammals. Coccidiostat; growth stimulant.

The Uses of Narasin from Streptomyces auriofaciens

Narasin (4-methylsalinomycin) is a polyether antibiotic isolated from Streptomyces aureofaciens in 1978. Although narasin is a close analogue of salinomycin, the metabolites are produced by different species and are not co-metabolites. Narasin shows broad spectrum activity against Gram positive bacteria including anaerobes and mycoplasma, and also possesses antiviral and limited antifungal activity. Narasin is used in the animal health industry as an in-feed antibiotic and growth promotant.
