What is the difference between a bacterium and a virus?

Answer 1

Answer 1. A virus is not alive. Bacteria is. Bacteria can reproduce on their own, Viruses can't.

Answer 2. Both a virus and a Bacterium can get into you through your lungs if droplet breathed, coughed or sneezed out by someone infected near you, or through your digestive tract when you eat ir drink infected substances, or through your genitourinary system like when having sex, or by penetrating your skin such as through cuts or wounds or through hair follicles.

Once one gets in both a virus and a bacterium can multiply and so can colonise your body and that is what makes you ill. But they multiply in different ways and behave differently once inside you.

Dealing firstly with Bacteria, they are a group of single celled microorganisms, only some of which cause disease in humans, these being called pathogenic bacteria. Bacteria unlike viruses reproduce by dividing into two cells which in turn divide, As well as dividing some types of bacterium also multiply be each producing a spore, that is a single new bacterium protected by a tough membrane that can survive high temperatures and lack of nourishment.

Dealing secondly with Viruses, they are about one half to one hundredth the size of the smallest bacterium, and have a much simpler structure a single virus particle, known as a virion, consists simply of an inner core of nuclei acid surrounded by one or two protective shells known as capsids made of protein. These capsids are built from a number of identical protein subunits arranged in a highly symmetrical form usually either as a 20 faced solid or as a spiral tube. Surrounding the outer capsid may be another layers often lost when the virus invades a cell in a human body.

Many viruses begin to invade human cells and multiply near site of entry into you, such as in your nose where you breathed in. They may come into your lymphatic vessels and spread to the lymph nodes, and many move on to your blood and in some cases within a few minutes have spread to every part of your body so making you very ill.

The way a virus replicates is much simpler than a bacterium. The virus particle first attaches itself to and then injects itself into one of your cells, known as the host cells. The virus capsid then breaks down and the viral nucleic acid (DNA or RNA) contained inside is released.. The viral nucleic acid then replicates itself; the new copies of itself being made from raw materials in the host cell. Each of the new copies of the viral nucleic acid now makes a capsid for itself, then the newly formed virus particles get released in large numbers and the host cell may be destroyed

So they may make you ill by destroying or severely disrupting the activities of your body's cells they have invaded and start multiplying inside your specific large organs so causing disease when your vital organs are affected, as well in some cases by the virus interacting with the chromosomes of their host cells and by weakening the cell mediated arm of your body's immune system so your body's normal defence against a wide range of infections may be lost.

With illnesses caused by bacteria, your immune systen is sometimes enough by itself to make you recover. Bit for bacteria caused diseases overall the main form of treatment is by antibiotic drugs, but antibiotic drugs cannot help you if you have a disease caused by vurus. With bacteria diseases some anti biotics such as penicillin are themselves bactertia; and destroy the invading bacteria, others such as tetracycline work by preventing the invading bacteria from multiplying further. Some bacteria illnesses like tetanus, botulism and gas gangrene are treated by an injection into you of an antiserum.

While antibiotics are good for treating illnesses caused by bacteria, Antibiotics will not kill viruses and taking them for a viral disease is pointless. Overall viruses are more difficult than bacteria to combat with drugs because it is very difficult to design drugs that kill viruses. Drugs known as interferons, a group of natural substances produced by virus infected cells van protect uninfected cells. Otherwise treatment of viral infections depends mainly on alleviating your illness symptoms and trusting your body's immune defence to bring about a cure. Alternatively immunisation by highly effective vaccines before the virus gets into you are available to protecting you from getting many bad viral illnesses such as smallpox, polio, measles, , mumps, rubella, hepatitis B, yellow fever and rabies before the virus starts replicating and colonising your body.

Answer 3

• bacteria are cellular, viruses are acellular
• bacteria have one DNA chromosome, viruses can have one RNA or DNA piece
• bacteria have cytoplasm, viruses don't
• bacteria have metabolism, viruses don't
• etc.

Answer 4

Viruses and bacteria are two very distinctly different types of organisms. The most obvious differences are their structure and how they interact with their environment. A bacteria is a unicellular, complete, living organism. It has many different parts, each with its own purpose. A virus however is not technically "living". Their structure consists of genetic material (DNA and RNA) covered by a protein coat. They cannot function by themselves, and must reproduce in inside another cell. This is the second main difference between bacteria and viruses. For example, a pathogenic bacteria causes damage by attacking human cells, either by physically destroying or basically poisoning them form the outside. A virus on the other hand will actually enter the human cell, and combines its DNA or RNA with the cells productive abilities to cause harm by changing the way the cell functions, in essence "hijacking" it. Eventually this kills the cell, releasing the virus that has reproduced to infect many other cells. There are many more differences, but these are the main two.

Answer 5

• bacteria are living cells with active metabolism and the ability to reproduce themselves
• viruses are parasites that must take over living cells, forcing that cell to replicate them; when not parasitizing a cell a virus is basically a microscopic "crystal" of proteins and one nucleic acid strand

Answer 6

Bacteria are living, complete cells.

Viruses are not alive and technically can consist only of DNA or RNA. They need hosts to multiply.

Answer 7

bacteria has a cell wall and the virus doesn't also the virus has a protein coat and bacterium doesn't
