Description

This video shows real footage of bacteria rapidly dividing.

Microbiologist Brett Finlay explains that when bacteria are grown in the lab, with unlimited food, they reach very large numbers quickly. Bacteria grow much more slowly in human intestines because they are competing for resources with other bacteria.

This clip is from a 1999 Holiday Lecture Series, 2000 and Beyond: Confronting the Microbe Menace.
