A life-changing relationship. Host H. lacusprofundi is the rod-shaped microbe dominating the image; Ca. N. antarcticus is the small circle attached on the right.And researchers have found that these parasites are very selective about the resources they steal from the body of their host.. N. antarcticus belongs to a group of archaea known as DPANN – small archaea.
The researchers also noted that some of the changes in infected hosts' membrane composition may be a defensive response to the parasite. Bolstering defenses and altering lipid production in response to a parasite, the researchers say, could have implications for how the host responds to other external influences, such as changing temperatures or acidity levels.

Archaea can be picky parasites | ScienceDailyA parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic microbes, so-called DPANN archea. Their study shows that these archaea are very 'picky eaters', which might drive their hosts to change the menu.

How parasites shape complex food websA new study sheds light on how parasites, often overlooked, can dramatically affect the balance between predator and prey populations. Researchers developed a groundbreaking mathematical framework that predicts when predators, prey, and parasites can coexist, considering factors like random fluctuations and parasite effects on both populations.
