Summary:
- Researchers have discovered a new type of parasite that is resistant to the common anti-parasitic drug ivermectin.
- This parasite, which infects a species of roundworm, has never been seen before and appears to have evolved mechanisms to evade the effects of ivermectin.
- The discovery of this resistant parasite highlights the importance of continued research and development of new anti-parasitic drugs, as well as the need to use existing drugs responsibly to prevent the emergence of further drug-resistant parasites.
