The first complete genome sequence of S. avermitilis was completed in 2003.^[4] The genome consists of a single chromosome with a linear structure, unlike most bacterial genomes, which exist in the form of circular chromosomes.^[5]

Avermectins are industrially derived from the fermentation products of S. avermitilis.^[1][6] Avermectin itself was discovered by the Satoshi Ōmura group^[6] and first disclosed in Burg et al. 1979.^[1] One of the most widely employed drugs against nematode and arthropod infestations is the avermectin derivative ivermectin, as well as abamectin, a widely used insecticide and antihelmintic.
