Phage biology

Is the phage virus harmful to humans

Bacteriophages are of two types: lytic and lysogenic bacteriophages. Lytic phages are virulent, causing lysis of bacterial cells, allowing lytic phage progeny to be released into the environment. Due to their lytic properties specific to bacteria, they are supposed to be used as alternative therapeutics against multi-drug resistant bacteria. On the other hand, lysogenic phages are the viruses that integrate their whole genome into bacterial chromosome and maintain their DNA replications along with bacterial genome within bacterial cells. …

10 phage used in the food industry

Antibiotic resistance has become a major concern of this world due to misuse and rapid use of antibiotics. This problem causes scientist to find new strategies to combat bacterial pathogens. As many studies have been done for this purpose, phage therapy is mostly discussed topic at present days.

Frederick Twort in 1915 and Fe’lix d’He’relle in 1917 first observed that viruses have antibacterial activities. Since then, phages had been being used against dome bacteria. But due to discovery of antibiotics in 1929 and its rapid emergence in 1940, the concept of phage application died out in west. …
