Felix d'Hérelle

Definition

Felix d'Hérelle was a Canadian microbiologist known for his discovery of bacteriophages, viruses that infect and kill bacteria. His groundbreaking work in the early 20th century laid the foundation for using these viruses in medicine and biotechnology, particularly as a potential treatment for bacterial infections. D'Hérelle's enthusiasm for bacteriophages has led to their applications in various fields, showcasing their significance in the fight against antibiotic-resistant bacteria.

5 Must Know Facts For Your Next Test

1. D'Hérelle first identified bacteriophages in 1917 while studying an outbreak of dysentery and proposed their use as antibacterial agents.
2. He coined the term 'bacteriophage', which means 'bacteria eater', highlighting the viruses' ability to specifically target and destroy bacteria.
3. D'Hérelle's work significantly influenced the development of phage therapy, especially in Eastern Europe and the former Soviet Union, where it was used as a treatment method long before becoming popular in the West.
4. In addition to his work with bacteriophages, d'Hérelle also contributed to understanding the role of microorganisms in disease and helped advance the field of microbiology.
5. Despite facing skepticism from some in the scientific community, d'Hérelle's research on bacteriophages has gained renewed interest due to the rising threat of antibiotic-resistant bacteria.
