Streptomyces avermitilis
Streptomyces avermitilis is a bacterium species in the genus Streptomyces. This bacterium was discovered by Satoshi Ōmura in Shizuoka Prefecture, Japan.
The first complete genome sequence of S. avermitilis was completed in 2003. This genome forms a chromosome with a linear structure, unlike most bacterial genomes, which exist in the form of circular chromosomes.
Avermectins are produced from S. avermitilis. 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.
