Bacteria+Vs.+Viruses

VIRUSES -Viruses are none living until it invades a cell -Viruses attack specific cells -Most viruses are too small to be seen with a light microscope.( smaller then Bacteria)

Good Virus: Phage virus eats bacterias which could be harmfull to humans, but does nothing to humans. -An electron micrograph of bacteriophages attached to a bacterial cell

Bad Virus: **chicken pox** is a highly contagious illness caused by primary infection with varicella zoster virus



BACTERIA -Prokaryotic cells: Lack membrane bound organelles. Smaller, simpler. -Micro organism -Bacteria's role in the environment is to decompose Classifying bacteria: Shape -Rod= Bacilli -Sphere= Cocci -Spiral= Spirilla -There are other more complex shapes that do exist. Gram+/ Gram- Autotrophic or Heterotrophic Need oxygen / Don't need oxygen

Good: Lactobacillus: Some Lactobacillus species are used industrially for the production of yogurt  cheese, saukraut, pickles, beer, wine, cider, kimchi, chocolate, and other fermented foods, as well as animal feeds, such as silage. - //Lactobacillus//

Bad: Anthrax: Anthrax is an acute disease caused by the bacteria //Bacillus anthracis//. Most forms of the disease are lethal, and it affects both humans and other animals. There are effective vaccines against anthrax, and some forms of the disease respond well to antibiotic treatment. -Microphotograph of a Gram stain of the bacterium //Bacillus anthracis//, the cause of the anthrax disease
