The person credited with first discovering bacteria is Dutch tradesman and scientist Antony van Leeuwenhoek. Escherichia coli or E. coli is a type fecal coliform bacteria that is commonly found in the intestines of animals and humans. The subsequent discovery and partial characterization of bacteriophages by Frederick Twort and Félix d'Herelle further catalyzed the field, and by the early 20th century many viruses had been discovered.
