Frederick William Twort
English microbiologist and bacteriologist who discovered a virus that attacked bacteria, later known as bacteriophages. While the superintendent of a veterinary dispensary in London, Twort isolated himself and engaged in solitary research for 35 years, interrupted only by World War I. Little recognized in his life, he discovered bacteriophages while studying cultures of Staphylococcus aureus (a bacterium responsible for boils), and in a 1907 paper established the idea of mutation and adaptation of bacteria. He also did pioneering work on the nutritional needs of bacteria. In 1944 his laboratory was destroyed by wartime bombing.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
