1. Bacteria and virus

4. BacteriaVirus Living attributes: Living organismOpinions differ on whether viruses are a form of life, or organic structures that interact with living organisms. Number of cells: Unicellular; one cellNo cells; not living Structures: DNA and RNA floating freely in cytoplasm. Cell wall and cell membrane DNA or RNA enclosed inside a coat of protein

5. BacteriaVirus Ribosomes (Molecular protein synthesis machine) PresentAbsent Enzymes:YesYes, in some Nucleus:No Can cause disease?Yes Infection:LocalizedSystemic How is it treated?:AnibioticsVaccines prevent the spread and antiviral medications help to slow reproduction but can not stop it completely. Beneficial?:Question of the week

6.  We know that there are some bacteria DIRECTLY beneficial to humans.  Are there viruses, similar to bacteria, that DIRECTLY benefit humans?

7. BacteriaVirus 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)

13.  Dental infections account for approximately eighty percent of cases of Ludwig's angina.  infection of the gums surrounding the partially erupted lower (usually third) molars.  it is very important to obtain dental consultation for lower-third molars at the first sign of any pain, bleeding from the gums, sensitivity to heat/cold or swelling at the angle of the jaw.  Can also be caused by piercing tongue.  http://en.wikipedia.org/wiki/Ludwig%27s_angina
