Insights

Six novel bacteriophage species were identified, offering potential biocontrol agents. Seven isolates show promise for phage therapy against multidrug-resistant bacterial infections.

Area of Science:

  • Microbiology
  • Virology
  • Genomics

Background:

  • Bacteriophages are viruses that infect bacteria.
  • The rise of multidrug-resistant bacteria necessitates novel therapeutic strategies.
  • Phage therapy presents a promising alternative to conventional antibiotics.

Purpose of the Study:

  • To identify and characterize novel bacteriophage species.
  • To evaluate the potential of these bacteriophages for therapeutic applications.
  • To expand the understanding of biocontrol agents against multidrug-resistant bacteria.

Main Methods:

  • Phylogenetic analysis of bacteriophage genomes.
  • Genome sequencing and comparative analysis.
  • Assessment of isolates for phage therapy suitability.

Main Results:

  • Six new bacteriophage species were discovered across four genera: Drulisvirus, Mosigvirus, Kayfunavirus, and Kagunavirus.
  • Genome similarity among the new species ranged from 77.2% to 94.5%.
  • Seven isolates demonstrated suitability as candidates for phage therapy.

Conclusions:

  • The newly identified bacteriophages contribute to the diversity of known phage species.
  • These bacteriophages represent valuable candidates for developing phage therapy strategies.
  • This research expands the arsenal of biocontrol alternatives against challenging bacterial infections.

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...

CRISPR and crRNAs02:53

CRISPR and crRNAs

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

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.
