Can you bring worms back to life?

MOSCOW: A sample of microscopic worms that were suspended in a deep freeze in Siberia for 42,000 years have come back to life after being defrosted, scientists say. After defrosting the worms, researchers saw them moving and eating, making this the first evidence of “natural cryopreservation” of multicellular animals.

The worms were originally transferred through the horticultural trade, probably in the soil bulbs of European plants being carried to the Americas.

What kind of parasites live in human intestine?

Protozoa. Protozoa are microscopic, one-celled organisms that can be free-living or parasitic in nature. They are able to multiply in humans, which contributes to their survival and also permits serious infections to develop from just a single organism. Transmission of protozoa that live in a human’s intestine to another human typically occurs…

How big does a parasite have to be to be an organism?

Parasites range from microscopic in size to over 30 meters in length. A parasite is an organism that lives within or on a host. The host is another organism. The parasite uses the host’s resources to fuel its life cycle.
