Myoviridae is a family of viruses known as bacteriophages, which specifically infect bacteria. They are characterized by their long, contractile tails and icosahedral heads. These viruses play a crucial role in regulating bacterial populations and can be found in various environments, including soil and water. Members of the Myoviridae family are important tools in molecular biology and biotechnology. They can be used in phage therapy to target and kill antibiotic-resistant bacteria. Their unique structure and ability to infect specific bacterial strains make them valuable for research and potential medical applications.
