Bacteria are unicellular organisms that are a few micrometers long and have many shapes - curved rods, rods, spiral, spheres.

Virus us a sub-microscopic particle ranging in size from 20 nm to 300 nm.

What is viral DNA and bacterial DNA?

Viral DNA is the very simple DNA that runs the processes of viruses. Viruses can not live without feeding off of higher-level organisms, so there are not considered to be true life. If you know some about DNA, viruses have around 10,000 nucleotides. Bacterial DNA is much more complex, with millions of nucleotides. Bacteria are certainly life, because they often exist on their own. Both viruses and bacteria use DNA, but the difference is how much and how complex it is.


four difference between virus and bacteria?

Viruses are (debatably) not alive while bacteria are; meaning they are smaller and require a living host to survive. Bacteria are killed with antibiotics, but viruses are not.


What are the difference between antiviral immunity and anti bacterial immunity?

Antiviral immunity targets viruses by recognizing viral antigens and activating immune responses specific to viral infections. Antibacterial immunity targets bacteria by recognizing bacterial antigens and activating immune responses specific to bacterial infections. The mechanisms of immune cell activation, the types of cells involved, and the specific responses generated differ between antiviral and antibacterial immunity.


What are viruses that attach to bacteria and inject their hereditary material?

Viruses that attach to bacteria and inject their hereditary material are known as bacteriophages, or phages. These viruses specifically target bacterial cells, attaching to their surface and injecting their DNA or RNA into the host. Once inside, the phage can hijack the bacterial machinery to replicate itself, often leading to the destruction of the bacterial cell in a process called lysis. Bacteriophages are important tools in molecular biology and have potential applications in phage therapy to combat antibiotic-resistant bacterial infections.

What is difference between viral disease and bacterial disease?

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.


What is the difference between bacterial and viral diarrhea?

Even though the symptoms are mostly the same, bacterial diarrhea is caused by bacteria, and viral diarrhea is caused by viruses. This means that the treatment for each is different, since the same medicines do not affect both bacterias and viruses.


Difference between virus and antivirus?

Viruses destroy computers,BUT Anti-Viruses destroy viruses.


How can you tell the difference between bacteria and viruses?

Bacteria are single-celled organisms that can be seen under a microscope, while viruses are smaller and can only be seen using an electron microscope. Bacteria can reproduce on their own, while viruses need to infect a host cell to replicate. Additionally, antibiotics can treat bacterial infections, but not viral infections.


What are viruses that prevent bacteria?

Viruses that prevent bacterial infections are called as "bacteriophages".


True or false viruses are smaller than bacterial cells?

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.

Which difference between bacteria and viruses shows that bacteria are living organisms and viruses are not?

Viruses require a living organism to do anything - most especially to reproduce.


What is the difference between and antiviral drug and an antibiotic drug?

No. Antivirals work to limit the reproduction of viruses, and antibiotics work to kill bacteria. Antivirals do not kill bacteria, and antibiotics do not kill viruses.

What is the differents between bacterial laryngitis and viral laryngitis?

To understand the difference between bacterial laryngitis and viral, we must first have a good understanding of the difference between bacteria and viruses. Bacteria are living single celled-organisms that can live outside of a living host and multiply on surfaces such as telephones, door handles, counters, etc. Bacteria infect a host and reproduce in order to multiply. Viruses are non-living organisms that infect a host and then "reprogram" the host's cells to do the job of producing more virus. The difference between bacterial laryngitis and viral laryngitis, is bacterial laryngitis is not systemic, meaning that it only attacks one area of the body particularly the larynx (voice box) or immediate surrounding areas of the throat. Whereas viral laryngitis is systemic meaning that it causes other symptoms such as runny nose, congestion, sneezing, coughing, etc. The more "cold-like" symptoms you have, the less likely you are to have the bacterial version of laryngitis. Also, the presence of a fever points more towards bacterial laryngitis than viral. Bacterial laryngitis is highly contagious where viral is not. Bacterial laryngitis can be spread very easily to others because it is an airborne bacteria. So if you suspect that you have the bacterial version of laryngitis, stay away from others and take precautions such as washing your hands and using antibacterial hand sanitizers. The treatment of viral laryngitis is lots of hot, clear fluids such as tea and chicken broth and plenty of rest. Whereas the treatment of bacterial laryngitis is antibiotics perscribed from your doctor.
