### microbacteria:

Good bacteria
* Most good bacteria produce substances.
* Some good bacteria are in the soil and helps plants get vitamins to grow.
* are vital for the intestinal tract, fighting off germs.
* breaks down waste and toxins such as ammonia into relatively harmless nitrates.
* is needed to complete the cycle of changing ammonia into a useful and harmless state.
* make possible many of our food and beverages such as yogurt, cheese and beer.
* work in our intestine to keep the intestine wall clean and break food down further.

Gut bacteria
* Most gut bacteria are harmless types, and they can even provide essential nutrients to the host.
* Most gut bacteria cause infection
  - wind infection
* Most gut bacteria play essential roles
* Some gut bacteria have fibre.

### microbacteria:

Harmful bacteria
* Most harmful bacteria cause infection
  - intestinal infection
  - grow in water
* Some harmful bacteria are also immune to some antibiotics.
* Some harmful bacteria grow on membranes
  - outer membranes
* are practically non-existent in fresh, uncut meat
  - present in foods which are served raw
* can grow even in the refrigerator
  - in such an environment
  - multiply in the stuffing and cause foodborne illness
  - spread quickly in the kitchen and cause foodborne illness
* grow in food.
* is killed with proper cooking and handling
  - more likely to grow in the stuffing if it sits in the bird after cooking
* multiply quickly in kitchen towels, sponges and cloths.
* produce by-products like ammonia, purines and ethionine, which can cause cancer.
* proliferate in an unhealthy body.

Healthy bacteria
* Some healthy bacteria have fibre.
* Some healthy bacteria live within canals
  - vaginal canals
* prevent yeast and gram negative bacteria infections.

Helpful bacteria
* Some helpful bacteria live in digestive tracts.
* produce foods such as cheese and pickles.

Heterotrophic bacteria
* Most heterotrophic bacteria feed on materials.
* Some heterotrophic bacteria inhabit intestinal tracks
* can interfere with total coliform analysis.
* derive energy from the breakdown of organic molecules.
* require carbon compounds as a food source.

Intestinal bacteria
* manufacture vitamin K in the body.
* produces biotin.

Iron bacteria
* are nuisance organisms often associated with soluble iron in water
  - one type of chemoautotrophic bacteria
* create energy for growth by transforming dissolved iron into rust.
* feed on the iron in the water.
* forms a very obvious slime on the inside of pipes and fixtures.

Lactic bacteria
* Some lactic bacteria break down lactose.
* is added to give flavor.
* produce acetic acid by fermenting the sugar.

### microbacteria:

Lactobacillus
* beneficial bacteria which helps control overgrowth of disease causing bacteria.
* describes a certain type and group of bacteria.
* friendly bacteria that lives in intestines.
* genus of bacteria.
* helpful bacteria which is used to make pickles and cheese.
* is also available in powder and capsule forms at health food stores
  - the main enemy of the Candida
  - present in the small intestine
  - simply dried bacteria that occur naturally in unpasteurized whole milk
* primary competitor of candida for food in the intestine.
