FOSTER CITY, Calif.--(BUSINESS WIRE)--OXIS International Inc (OTCBB: OXIS), a biopharmaceutical company focused on commercializing predictive biomarkers, clinical assays and neutraceutical and therapeutic products, announced today that it has signed a supply agreement for L-Ergothioneine (ERGO) with Golden Gourmet Mushrooms (GGM) of San Marcos, CA, a leading marketer to the equine industry of natural organic dietary supplements. The parties plan to market ERGO as a potential solution for the equine herpes virus, which has affected horses in at least 11 states, including leading horse racing and breeding states such as Florida, Connecticut, New York, Pennsylvania, Ohio and California. Recently, a mutation of the equine herpes virus (EHV-1) has appeared and gives the virus increased ability to multiply (more virus circulates in the horse’s body), infects cells of the nervous system and results in death of the horse.
