I wrote about these little dudes before— Viruses that parasitize other viruses, fleas on the backs of fleas. Its actually beneficial to the host to be infected with the virophage, because the virophage inhibits the growth of the virus, which kills the host. “The enemy of my enemy is my friend.”
Whats neat about the two virophages that were just discovered, is that they were discovered ‘in real life’. First guy might have been a weird lab/human contaminant thingie, an oddball– but it turns out it has lots of relatives irl too!
