Virus vs Bacteria

Cleaning for health, safety and the environment

Bacteria (singular: bacterium) are unicellular microorganisms. They are typically a few micrometers long and have many shapes including curved rods, spheres, rods, and spirals. A virus (from the Latin noun virus, meaning toxin or poison) is a sub-microscopic particle (ranging in size from 20–300 nm) that can infect the cells of a biological organism.   Bacteria Virus Ribosomes Present      Absent Living attributes Living organism Opinions differ on whether viruses are a form of life or organic structures that interact with living organisms. Number of cells Unicellular; one cell No cells; not living Structures DNA and RNA floating freely in DNA or RNA enclosed inside a coat of protein. cytoplasm. Has cell wall and cell membrane. Cell wall Peptidoglycan/Lipopolysaccharide No cell wall. Protein coat present instead. Treatment Antibiotics Vaccines prevent the spread and antiviral medications help to slow reproduction but can not stop it completely. Enzymes Yes Yes, in some Nucleus No No Virulence Yes Yes Infection Localized Systemic Benefits Some bacteria are beneficial Viruses are not beneficial. (e.g. certain bacteria are required in the gut) Viruses can be useful in genetic engineering. Reproduction Fission- a form of asexual reproduction Invades a host cell and takes over the cell causing it to make copies of the viral DNA/RNA. Destroys the host cell releasing new viruses. Size Larger (1000nm) Smaller (20 - 400nm)
Viruses are the smallest and simplest life form known. They are 10 to 100 times smaller than bacteria. The biggest difference between viruses and bacteria is that viruses must have a living host - like a plant or animal - to multiply, while most bacteria can grow on non-living surfaces. Bacteria are intercellular organisms (i.e. they live in-between cells); whereas viruses are intracellular organisms (they infiltrate the host cell and live inside the cell). They change the host cell's genetic material from its normal function to producing the virus itself. There are some useful bacteria but all viruses are harmful. Antibiotics can kill bacteria but not viruses. An example of a disease caused by bacteria is strep throat and an example of an affliction caused by a virus is the flu

Antibacterial cleaners

What’s in It?

Antibacterial cleaners usually contain water, a fragrance, a surfactant, and a pesticide named ‘Triclosan’. The surfactant breaks up the dirt, the pesticide kills the bacteria, the fragrance makes it smell good and the water holds the cleaner together. In antibacterial cleaners the pesticides are commonly quaternary ammonium or phenolic chemicals. They are known as antimicrobial pesticides.
Regular handwashing, particularly before and after certain activities, is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others.
