Bacteriophages, the tiny hunters, are like superheroes in the microbial world. Bacteriophages are viruses that can infect and replicate within bacteria, eventually leading to their destruction. They have a unique structure with a head containing genetic material and a tail that helps them latch onto bacteria."
Bacteriophages kill bacteria through a process called the lytic cycle, which involves several steps leading to the destruction of the host bacterial cell.
The first step is the attachment of the bacteriophage to the surface of the target bacterial cell. The tail fibers or receptor-binding proteins on the baseplate of the phage recognize and bind to specific receptors on the bacterial surface. This interaction is highly specific and determines the bacteriophage's ability to infect a particular type of bacterium.
The lytic cycle results in the death of the infected bacterial cell, and the released bacteriophages can continue to infect and kill other bacterial cells.
This process is highly efficient and specific, making bacteriophages valuable tools for targeted bacterial control and potential therapeutic applications in combating bacterial infections, particularly antibiotic-resistant bacteria.
Bacteriophages are being explored as a potential alternative or complementary therapy to antibiotics. Phage therapy involves the use of specific phages to treat bacterial infections, particularly those caused by antibiotic-resistant bacteria.
Phages can target and destroy these resistant bacteria, offering a promising solution to combat infections that are difficult to treat with traditional antibiotics.
