 Bdelloid rotifers

  • Microscopic freshwater animals ("crawling wheel-animals").

  • Simpler body structure than other animals (head, mouth, gut, muscles, nerves).

Defense Mechanism:

  • Acquire genes from bacteria and other microbes over millions of years (horizontal gene transfer).

  • New study shows they activate these acquired genes to fight infections.

  • Genes produce antibiotics and other antimicrobial agents.

  • First known example of animals using "stolen" genes for large-scale disease defense.

Potential Benefits for Humans:

  • Acquired genes are unique and not found in other animals.

  • Rotifers might be producing novel antibiotics with less toxicity to humans.

  • This discovery could aid the search for new drugs to fight bacterial and fungal infections.

Challenges of Current Antibiotics:

  • Many antibiotics come from bacteria and fungi.

  • These natural antibiotics can be poisonous or have side effects in humans.


Hope for the Future:

  • Studying rotifers might lead to the development of safer and more effective antibiotics for humans.
