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.
