How big is a bacteria compared to a virus?
Size. Bacteria are giants when compared to viruses. The smallest bacteria are about 0.4 micron (one millionth of a meter) in diameter while viruses range in size from 0.02 to 0.25 micron. This makes most viruses submicroscopic, unable to be seen in an ordinary light microscope.
What type of worms live in the intestines?
Trichinella worms are another type of roundworm that may pass to humans who eat undercooked or raw meats that contain the live larvae. The larvae then grow in the intestines. On reaching their full size, the Trichinella worms may leave the intestines and live in other tissues, such as the muscles.
