[RATIONAL ASPECTS OF BACTERIOPHAGES USE]
Summary
Bacteriophage therapy shows variable efficacy against bacterial pathogens. Optimizing bacteriophage production and application is crucial for effective treatment of Staphylococcus aureus, Salmonella, and E. coli infections.
Area of Science:
- Microbiology
- Bacteriophage Therapy
- Antimicrobial Resistance
Background:
- Bacteriophages (phages) are viruses that infect bacteria and have potential as therapeutic agents.
- Evaluating the lytic activity of various bacteriophages against clinically relevant bacterial strains is essential for their therapeutic application.
Purpose of the Study:
- To analyze existing bacteriophage applications and study their lytic activity against Staphylococcus aureus, Klebsiella pneumoniae, Salmonella, and Escherichia coli.
- To assess the effectiveness of specific bacteriophages, including monophages and polyvalent preparations.
Main Methods:
- Tested the lytic activity of staphylococcal, piopolyvalent, intestiphage, klebsiella, and coli-proteic bacteriophages.
- Utilized 380 Staphylococcus aureus strains and 279 Klebsiella pneumoniae cultures.
- Assessed sensitivity of Salmonella, Escherichia coli, and Proteus strains to specific bacteriophages.
Main Results:
- Staphylococcus aureus showed 71.6% sensitivity to staphylococcus bacteriophage and 86.15% to pi bacteriophage.
- Salmonella bacteriophage demonstrated 100% lytic activity against Salmonella spp.
- Escherichia coli sensitivity ranged from 66-100%, while Klebsiella and Proteus showed lower sensitivity (35% and 43.15%) to pi bacteriophage.
Conclusions:
- Bacteriophage therapy requires rationalized application, including improved production and sensitivity testing.
- Expanding bacteriophage spectra and standardizing concentration indications are necessary for effective use.
- Further research is needed to optimize bacteriophage cocktails and production methods.

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
79.9K
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...

Viral Replication: Lytic Cycle
2.5K
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...

CRISPR and crRNAs
19.5K
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...

Viral Replication: Lysogenic Cycle
2.3K
The lysogenic cycle is a crucial viral replication strategy that allows bacteriophages to persist within host cells without immediately destroying them. This process is primarily observed in temperate phages, such as bacteriophage lambda (λ), which infects Escherichia coli. The cycle allows the viral genome to persist across bacterial generations while keeping host cells viable.Integration of the Viral GenomeUpon infection, bacteriophage lambda attaches to the bacterial surface and injects...

Lysogenic Cycle of Bacteriophages
69.4K
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...
