Abstract
An acidic polycyclic ether antibiotic, having structure established by X-ray crystallography, is formed by fermentation of a novel microorganism, Streptomyces sp. ATCC 55028. This novel antibiotic is useful as an anticoccidial in chickens, in the prevention or treatment of swine dysentery, as a growth promotant in cattle and swine, and as an anthelmintic in mammals, particularly in dogs, cats, sheep, cattle and swine.
