Microbes are organisms that we can not see without using a microscope. The major groups of microbes:  Eubacteria  Archeobacteria  Protozoans  Fungi  Viruses

“True Bacteria” Three basic shapes coccibacillispirilla

Streptococcus pyogenes Causes Strep throat

The spirochete Treponema pallidum Causes Syphilis

Borrelia burgdorferi FA stain (CDC) Causes Lyme disease.. Ticks are the carriers.

Stained with violet dye Treated then with Iodine Rinsed with alcohol Stained again with Safranine purple pink Gram negative Gram positive Stains work differently with different cell walls

A Gram positive rod is Bacillus cereus. This bacteria is one of a group of gram postive rods which are aerobic, ubiquitous and form endospores.Because its spores are heat resistance, they are difficult to kill. Toxins may be produced. Food spoilage is a favorite of these organisms
