Insights

Photodynamic inactivation (PDI) effectively inactivates viruses using photosensitizers. This review compares PDI methods for mammalian viruses and bacteriophages, focusing on mechanisms and targets.

Area of Science:

  • Microbiology
  • Photochemistry
  • Virology

Background:

  • Photodynamic inactivation (PDI) utilizes photosensitizers to eliminate microorganisms.
  • The application of photosensitization for inactivating mammalian viruses and bacteriophages dates back to the early 20th century.
  • Understanding PDI is crucial due to the public health threat posed by mammalian viruses and the use of bacteriophages as model organisms.

Purpose of the Study:

  • To review current photodynamic inactivation approaches for bacteriophages and mammalian viruses.
  • To compare the state-of-the-art PDI for mammalian viruses with phage photoinactivation.
  • To highlight key mechanisms, molecular targets, and factors influencing viral inactivation.

Main Methods:

  • Literature review of photodynamic inactivation studies.
  • Comparative analysis of PDI techniques for viruses and bacteriophages.
  • Focus on mechanisms, molecular targets, and influencing factors.

Main Results:

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

Physical Methods for Controlling Microbial Growth: Temperature

Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

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...

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...

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
