A bacterium is a single-celled, often parasitic microorganism without a distinct nucleus or an organized cell structure. It has cytoplasm and a cell wall, but no true nucleus. Various species are responsible for decay, fermentation, nitrogen fixation, and many plant and animal diseases.
Bacteria are classed in a kingdom of their own, prokaryota (although, this kingdom may now be regarded as two separate kingdoms, archaea and bacteria).
A virus is a submicroscopic parasitic particle consisting of a strand of nucleic acid surrounded by a protein coat (capsid). It does not have cytoplasm or a nucleus and can only replicate within a host cell (has parasitic nature).
Viruses are not considered to be independent living organisms as the only characteristic of life they show is reproduction.
Bacteria is live and a virus is not. This also means that only a bacteria infection or illness can be killed with antibiotics.
A bacteria is a unicellular microorganism while a virus is a submicroscopic particle.
As simple as that a viral infection is caused by a virus and a bacterial infection is caused by a bacteria.
Bacteriophage is a type of virus that infects a bacteria.
virus is an arkaryotic organism while bacteria is prokaryotic
It is not. HIV is a virus. It has a completely different make-up from a bacteria. The most important difference between a bacteria and a virus is that a virus does not have the ability to replicate on its own. It needs a host, another cell, to reproduce, unlike bacteria which can reproduce on their own.
Bacteria have cellular organization and show metabolical reactions.Virus do not.Virus are complementary parasites.
antibiotics are only affective against bacteria, and a virus is different then bacteria
Bacteria is live and a virus is not. This also means that only a bacteria infection or illness can be killed with antibiotics.
It could be either.
The mimivirus
A pathogenic bacterium is alive while a virus is not.
Bacteria are not dependent on a host. :)
The term pathogen is a general term that is applied to an infectious agent, or germ. The infectious agent itself could be a bacteria or a virus that is harmful to a body. The virus is a type of pathogen.
Bacteria has both DNA and RNA where as Virus has either DNA or RNA
A virus that infects bacteria is called a bacteriophage
AIDS is a disease caused by the HIV virus. This is different than a bacteria.
