5 Must Know Facts For Your Next Test

  1. Streptomyces avermectinius produces avermectins, which are macrocyclic lactones used as antiparasitics.
  2. Avermectins from Streptomyces avermectinius can be chemically modified to produce ivermectin, a widely used antiparasitic drug.
  3. The discovery of Streptomyces avermectinius led to the development of treatments for parasitic infections in livestock and humans.
  4. This bacterium is found in soil and plays a significant role in natural decomposition processes.
  5. Avermectins target glutamate-gated chloride channels in parasites, leading to paralysis and death of the parasite.
