Streptomyces avermitilis is a type of bacteria belonging to the genus Streptomyces, which is known for its ability to produce various antibiotics. This soil-dwelling organism is particularly notable for its role in the production of avermectin, a compound used as an antiparasitic agent in both veterinary and human medicine. The bacterium thrives in nutrient-rich environments and is characterized by its filamentous structure. Streptomyces avermitilis is also studied for its potential in biotechnological applications, including the development of new drugs and agricultural products, due to its diverse metabolic capabilities.
