Bacteriophages are viruses that infect and replicate within bacteria. They do not infect human cells or other eukaryotic organisms. Bacteriophages are specific to infecting particular bacterial species or strains.
No. A virus must attack a cellular life form in order to survive.
Bacteria can attack and kill cells. White blood cells can kill bacteria.
That is certainly not true. There are for example viruses that routinely wipe out almost the entire tentworm population. There are others that attack bacteria. Some viruses attack cancers!
B. Colds are caused by viruses, and antibiotics only kill bacteria
Groups of viruses that attack a certain pack of bacteria.
The shape of a virus that attacks bacteria is typically cylindrical or polyhedral. These viruses that infect bacteria are known as bacteriophages and come in various shapes and sizes.
Viruses that attack prokaryotes are called bacteriophages. They specifically infect bacteria by injecting their genetic material into the bacterial cell, which then uses the cell's machinery to replicate and produce more viruses.
The best-known bacteriophage is T4 bacteriophage, which attacks E. coli bacteria.
Bacteria by injecting their genetic material into the bacterial cells, which causes the cells to produce more viruses until they burst, releasing new viruses to infect other bacteria. Bacteriophages are being researched as a potential alternative to antibiotics for treating bacterial infections.
A biodefence is any defensive measure taken against an attack using bacteria, viruses or toxins.
One thing bacteria has that animal and plant cells do not is restriction enzymes for fighting off the attack of viruses.
