Summary
Bacteriophages (phages), viruses that infect bacteria, show promise in combating antibiotic-resistant superbugs. Genetic engineering, particularly using CRISPR-Cas, enhances phage efficacy and specificity for novel therapies.
Area of Science:
- Microbiology and Virology
- Genetics and Genetic Engineering
- Infectious Diseases and Public Health
Background:
- Antibiotic-resistant bacteria, or superbugs, pose a significant global health threat, diminishing the effectiveness of current treatments.
- Nosocomial infections caused by these resistant pathogens are particularly challenging to manage.
- Conventional antibiotic therapies are increasingly failing against evolving bacterial resistance mechanisms.
Purpose of the Study:
- To review the potential of bacteriophages as a therapeutic strategy against antibiotic-resistant bacteria.
- To examine advancements in bacteriophage genetic engineering for improved efficacy and specificity.
- To discuss novel phage-based strategies and associated challenges for combating superbugs.
Main Methods:
- Review of current literature on bacteriophage therapy and genetic engineering techniques.
- Focus on modifications enhancing phage host range, lysis, and bacterial defense evasion.
- Analysis of the CRISPR-Cas system for precise phage genome manipulation.
Main Results:
- Genetic engineering, especially with CRISPR-Cas, enables precise modification of bacteriophages.
- Engineered phages demonstrate improved efficacy, specificity, and ability to overcome bacterial defenses.
- Novel strategies like phage cocktails and phage-antibiotic combinations are being developed.
Conclusions:
- Bacteriophage engineering offers a promising avenue for developing novel therapies against superbugs.
- CRISPR-Cas technology is pivotal for creating enhanced and specific phage-based treatments.
- Responsible research into phage engineering is crucial for safe and effective deployment against antibiotic resistance.

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...

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...

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...
