Escherichia coli: A Common Intestinal Bacteria

Overview

Escherichia coli (E. coli) is a rod-shaped, Gram-negative bacterium commonly found in the intestinal microbiome of humans and animals.

Ecological Importance

While most E. coli strains are harmless, certain strains, such as Shiga toxin-producing E. coli (STEC), can cause severe intestinal infections.

Metabolic Capabilities

E. coli is a chemoheterotroph, meaning it obtains energy from chemical sources. Its growth medium requires a source of carbon and energy.

Scientific Significance

E. coli is a well-studied prokaryotic organism and serves as a model system for studying fundamental biological processes, including genetics, metabolism, and microbial ecology.
