First we need to clarify your question. Viruses (like the one that causes the common cold) are NOT bacteria. Viruses are their own subset, in fact they aren't even considered 'living' organisms.
Viruses that attack bacteria are called bacteriophage, if that is what you're interested, I suggest a search using that term.
When it comes to viruses that attack humans, the nastiest are probably some of the STDs, like herpes, that are recurrent and you can never be cured of. An obvious answer is HIV-AIDS, an incurable illness from a virus. Also, viral meningitis is a horrible disease where the virus attacks the meninges (or brain / nerve tissue) and cause paralysis and in many cases death.
Viruses that prevent bacterial infections are called as "bacteriophages".
True. Viruses are smaller than bacterial cells. Bacterial cells are living organisms and are much larger in size compared to viruses, which are non-living particles that require a host cell to replicate.
Flu and HIV
No, bacterial viruses with a polyhedral head typically have a tail associated with the head structure. These viruses are known as bacteriophages. The tail plays a critical role in attaching to the host bacteria and injecting the viral genetic material into the bacterial cell for replication.
It is caused by viruses not by bacteria.
retro virus = any of a family of single-stranded RNA viruses having a helical envelope and containing an enzyme that allows for a reversal of genetic transcription, from RNA to DNA rather than the usual DNA to RNA, the newly transcribed viral DNA being incorporated into the host cell's DNA strand for the production of new RNA retroviruses: the family includes the AIDS virus and certain oncogene-carrying viruses implicated in various cancers.
Bacterial diseases are diseases caused by bacteria, in contrast to those caused by parasites, viruses, or fungi.
It is Neutralization
Antibiotics treat bacterial infections, they have no affect on viruses. Vaccinations treat viruses.
One is caused by bacteria and the other is caused by viruses. Only bacterial diseases can be successfully treated with antibiotics. Bacteria are alive, viruses are not. Viruses invade bacteria and take over their properties, including the ability to infect.
Bacteriophages, or phages, are viruses that specifically infect and destroy bacteria, not other viruses. They attach to bacterial cells, inject their genetic material, and ultimately cause the bacteria to lyse, releasing new phage particles. While phages are effective against bacterial infections, they do not target or eliminate other viruses. Therefore, their role is primarily in bacterial control rather than viral destruction.
