### microbacteria:

Listeria
* Can Be Deadly.
* also infects domestic and wild animals, livestock and fowl.
* are bacteria often found in soil and water, which can cause serious illness.
* bacteria particularly dangerous to pregnant women, their fetuses and newborns.
* binds to receptors on the cell surface, and is phagocytosed.
* can also cause abortion, diarrhea and speticemia
  - miscarriages or stillbirths, even if the expectant mother feels no symptoms
  - serious flu-like symptoms in healthy individuals
  - contaminate other foods
  - grow on soft cheeses during their ripening period
  - trigger miscarriages and stillbirths
  - be present in raw milk and soft cheese products or raw vegetables
  - become airborne
* can cause fever, abdominal cramps, bloodstream infection, meningitis, and stillbirths
  - headaches, nausea and neck stiffness
  - severe headaches, stiffness, nausea, and diarrhea
  - high fever, nausea, stiff necks and miscarriages in pregnant women
  - meningitis and stillbirths
  - problems for pregnant women, children and the elderly
* can contaminate other food through spills in the refrigerator
  - raw vegetables and poorly preserved processed foods
* can grow and multiply at low temperatures
  - at refrigeration temperatures
  - even in refrigerated foods
  - slowly at refrigerated temperatures
  - multiply slowly in refrigerated foods
  - spread from one surface to another
* common bacteria and is very difficult to eliminate
  - organism found in nature
* eventually resides in the central nervous system casing inflammations and tissue damage.
* exhibits a peculiar tumbling motility.
* gram negative bacterium that is present in soil.
* grow inside phagocytes and proliferate within macrophages.
* hardy bacteria with lots of opportunities to spread.
* has an interesting intracellular lifecycle.
* is acquired by ingestion of contaminated food products
  - also a human pathogen
  - an organism that is able to reproduce at refrigeration temperatures
  - caused by bacteria found in soil, water and plant matter
  - commonly present in soil, vegetation and sewage
* is found in soil and can contaminate food such as vegetables, meat chicken and milk
  - throughout nature, in animals, plants, water, and soil
* is killed by cooking and pasteurization
  - cooking, but it can grow and multiply in refrigerators
  - pasteurization and by thoroughly cooking raw food from animal sources
  - one of the most dangerous foodborne pathogens
  - only dangerous to pregnant women, their babies and people with a lowered immune system
  - particularly dangerous for pregnant women and people with reduced immunity to infection
  - well controlled in American food products
* rare but important cause of human illness in the United States.
* serious flu-like illness.
* tends to flourish in hidden places.
* type of bacteria that can contaminate food
  - food poisoning that can cause miscarriage, premature labour and stillbirth
* uses the cellular machinery to move around inside the host cell.

Magnetic bacteria
* live and die within the cells of our body.
* use the properties of a magnetic field in order to migrate magnetically.

Magnetotactic bacteria
* are also multicellular
  - among the bacteria types being studied
  - unusual in several ways
* dislike oxygen.

Many bacteria
* Most many bacteria have mechanisms.
* Some many bacteria carry out fermentation.
* Some many bacteria cause diarrhea
  - diseases
* Some many bacteria excrete organic compounds
  - small organic compounds
  - live in intestines

Marine bacteria
* Most marine bacteria adhere well to fish mucus.
* Some marine bacteria eat seaweed.
* Some marine bacteria excrete compounds
* are an essential component of the marine environment
  - extremely important, but little understood, group
