- nkurz 1y agoI appreciate the attempt to ground the discussion in research, but as MillironX pointed out elsewhere, ivermectin turns out to be less effective on Cochliomyia hominivorax (which the article is about) than on Chrysomya bezziana (which the paper you cited is about).
- TeaBrain 1y agoThat is interesting, although I'm not seeing the comment you're referencing. I read the article this morning, but I hadn't noted that there were possibly multiple types of screw worm. Looks like the Cochliomyia hominivorax is only one that the Americas typically have to deal with, so that was the only one that made sense in the context. However, that a anti-parasitic is more effective at killing one type of screw worm than another doesn't mean much by itself. That statement would hold true even if it had 99% efficacy against one type vs 98% efficacy against another.
- nkurz 1y agoThe comment I referred to is here: https://news.ycombinator.com/item?id=43881065#43882771 https://news.ycombinator.com/item?id=43881065#43882771. It links to https://pubmed.ncbi.nlm.nih.gov/9403981/ https://pubmed.ncbi.nlm.nih.gov/9403981/. Looking at the abstract now (I hadn't before) it claims that injected doramectin was fully effective while ivermectin had limited effectiveness (29% of cases not treated). It doesn't seem to give a comparison between types of screwworm.
