History

In 1978, an actinomycete was isolated at The Kitasato Institute from a soil sample collected at Kawana, Ito City, Shizuoka Prefecture, Japan. Later that year, the isolated actinomycete was sent to Merck Sharp & Dohme Research Laboratories for testing. Various, carefully controlled broths were fermented using the isolated actinomycete. Early tests indicated that some of the whole, fermented broths were active against Nematospiroides dubius in mice over at least an eightfold range without notable toxicity. Subsequently, the anthelmintic activity was isolated and identified as a family of closely related compounds. In early October 1978, a team from Merck Sharp & Dohme Research Laboratories led by Richard W Burg, and Ruiko Oiwa and Satoshi Omura of The Kitasato Institute and Kitasato University, presented their findings at the 18th Interscience Conference on Antimicrobial Agents and Chemotherapy, Atlanta, Georgia.In 2002, Yoko Takahashi and others at the Kitasato Institute for Life Sciences, Kitasato University and at The Kitasato Institute, proposed that Streptomyces avermitilis be renamed Streptomyces avermectinius.
