Insights

Bacteriophages are a promising alternative to antibiotics for treating infections caused by multidrug-resistant Staphylococcus aureus. Researchers sequenced the genome of S. aureus phage Maine, identifying it as a Twort-like myophage.

Area of Science:

  • Microbiology
  • Genomics
  • Virology

Background:

  • Multidrug-resistant *Staphylococcus aureus* poses a significant global health threat.
  • Traditional antibiotics are becoming less effective against resistant bacterial strains.
  • Bacteriophages are viruses that infect bacteria and represent a potential alternative therapeutic strategy.

Purpose of the Study:

  • To sequence and characterize the genome of *Staphylococcus aureus* phage Maine.
  • To classify phage Maine within existing phage taxonomy.
  • To contribute genomic data for the development of phage therapy.

Main Methods:

  • Whole-genome sequencing of *S. aureus* phage Maine.
  • Bioinformatic analysis to predict genome features, including terminal repeats.
  • Comparative genomic analysis to determine phylogenetic relationships with other *Staphylococcus* phages.

Main Results:

  • The complete genome of *S. aureus* phage Maine was sequenced, measuring 141,712 base pairs.
  • Phage Maine was identified as a myophage with 9,019-bp predicted terminal repeats.
  • Genomic analysis revealed high similarity to other *Staphylococcus* phages, placing it in the Twort-like group.

Conclusions:

  • The genomic characterization of phage Maine provides valuable data for phage therapy development.
  • Phage Maine's classification within the Twort-like group aids in understanding *Staphylococcus* phage evolution.
  • This study supports the potential of bacteriophages as a viable alternative to antibiotics for treating *S. aureus* infections.

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 Bacteriophages01:30

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...

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...

Genomic DNA in Prokaryotes00:46

Genomic DNA in Prokaryotes

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...
