Phage conversion
from class: Microbiology Definition Phage conversion is a process where a bacterium acquires new traits due to the integration of prophage DNA into its genome. This can result in changes such as increased virulence or antibiotic resistance.
congrats on reading the definition of phage conversion . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Phage conversion often occurs when a bacteriophage integrates its genetic material into the bacterial chromosome. This process can lead to the expression of new genes that were not originally present in the bacterium. A classic example is the diphtheria toxin, which is produced by Corynebacterium diphtheriae only when infected by a specific phage. Phage conversion can contribute to the spread of antibiotic resistance among bacterial populations. It plays a significant role in the evolution and adaptation of bacterial pathogens. Review Questions What is phage conversion and how does it affect bacteria? Can you provide an example of a bacterial trait acquired through phage conversion? How does phage conversion impact antibiotic resistance?
