Theodor Escherich

Theodor Escherich was a German pediatrician and bacteriologist, best known for discovering the bacteria Escherichia coli (E. coli) in 1885. This microorganism is a common inhabitant of the human intestinal tract and plays an essential role in digestion. While most E. coli strains are harmless, some can cause serious foodborne illnesses. Escherich's work was significant in microbiology and has helped advance our understanding of gut health, infectious diseases, and food safety. His research laid the groundwork for future studies on the role of bacteria in human health and disease.
