Bacteriophages: Definition & History Bacteriophages are viruses that infect and destroy bacteria. They have been referred to as bacterial parasites, with each phage type depending on a single strain of bacteria to act as host. Nucleic acid Nucleic acid Capside Capside Envelope Envelope tail tail
71
Bacteriophages: Classification At present, over 5000 bacteriophages have been identified by electron microscopy and can be divided into 13 virus families. Based on morphology and nucleic acid are classified

73
Bacteriophages: Lysogenic Cycle
74
Bacteriophages: Lysogenic Conversion Some lysogenic phage carry genes that can enhance the virulence of the bacterial host. For example, some phage carry genes that encode toxins. These genes, once integrated into the bacterial chromosome, can cause the once harmless bacteria to release potent toxins that can cause disease.
