Insights

A new method preserves bacteriophages, essential viruses that infect bacteria, by storing them within infected host cells at -80°C. This approach maintains high phage and host viability for long-term bacteriophage preservation.

Area of Science:

  • Microbiology
  • Virology
  • Biotechnology

Background:

  • Bacteriophages (phages) are crucial tools in molecular biology and potential therapeutic agents.
  • Effective, universal long-term storage methods for phages are currently lacking.
  • Preservation methods impact phage viability and usability.

Purpose of the Study:

  • To develop and evaluate a novel, simple method for the long-term preservation of bacteriophages.
  • To assess the viability of both phages and their host cells after storage using the proposed method.
  • To determine if this method can be standardized for routine phage preservation.

Main Methods:

  • Randomly selected tailed bacteriophages were used for the study.
  • Phages were stored within their infected bacterial host cells.
  • Storage was conducted at a temperature of -80°C.
  • Phage and host cell viability were assessed post-storage.

Main Results:

  • Bacteriophages stored within infected cells at -80°C showed no significant loss in viability.
  • Host bacterial cells also maintained viability after the storage period.
  • The method proved effective for the tested population of tailed phages.

Conclusions:

  • Storing bacteriophages within infected cells at -80°C is a viable and effective long-term preservation strategy.
  • This method offers a simple and potentially universal approach to phage preservation.
  • The findings suggest this technique could be adopted as a standard for maintaining phage collections.

DNA Bacteriophages

Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...

Lytic Cycle of Bacteriophages

Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the lytic replication...

Viral Replication: Lytic Cycle

Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...
Lysogenic Cycle of Bacteriophages00:43

Lysogenic Cycle of Bacteriophages

In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...
