Koch's Postulates

A set of four criteria designed to establish a causal relationship between a microbe and a disease. They involve isolating the microbe from a diseased organism, cultivating the microbe in pure culture, introducing the microbe into a healthy organism, and reisolating the microbe from the newly infected organism.

Globules of Kara

Round, lipid droplets found in the cytoplasm of some bacteria. They are involved in energy storage and buoyancy regulation.
