Definition
| It is a simple microorganism, Characterized by 3 major basic shapes: Round, Rod, and Spiral. Has staining characteristics |
|
|
Term
| What are Staining Characteristics |
|
Definition
| Used to highlight micro-organisms to determin shape, and arrangement: Gram Postitive - Thick cell wall/purple. Gram negative: Thin cell wall colorless or red |

Term
|
Definition
| A substance produced by microorganisms that kill bacteria |
|
|
Term
|
Definition
| Resting structures made by some bacteria for survival under adverse conditions such as extreme heat, lack of water and exposure to toxic chemicals (can lie dormant for long time even hundreds of years) |

Term
| What are some examples of Bacteria? |
|
Definition
| Tuberculosis and Sextually Transmitted Infections |
|
|
Term
|
Definition
| Non-cellular entities that are parasites of cells (Derives nutrients from lifing host without benefit to host, cant reproduce by self, can t metabolize energy or proties , consist of DNA or RNA but not both. |

Definition
| - Fungi (Yeast, Molds), - Protozoa(Amoebic dysentery, Giardiasis, Malaria), Algae (Red Tide) |
|
|
Term
|
Definition
| Microscopic animals found in soil, water, and in the intestinal tract of animals (classified by their means of movement) |
|
|
Term
| What are examples of Protozoa |
|
Definition
| Flagellates, Ciliates, Pseudopdia, Some cant move by themselves to be carried |
|
|
Term

|
Definition
| Yes allowing you to catch some protozoa from other animals |
|
|
Term
| What are some medically important protozoa? |
|
Definition
| Amoebic dysentery, Giardiasis, Malaria |
|
|
Term
|
Definition
| May be unicellular or multicellular, covert carbon dioxide to oxygen during photosynthesis, mostly aquatic or on trees if sufficient moisture availabe, prefer light. EXAMPLE: Red tides that produce toxin that paralyzes chell fish |
|
|
Term
| Describe microbial growth |
|
Definition
| Environmental requirements for growth can be divided into two categories: Physical and Chemical. |
|
|
Term
| What are physical requirements for microbial growth |
|
Definition
| Light energy source (photosynthesis), Temperature (3 groups based on preferred range of temps), PH (acidity - grow best in narrow range of pH neutrality between 6.5 and 7.5) |
|
|
Term
| What are chemical requirments for Microbial growth |
|
Definition
| Water: Hydrophilic (plenty of moisture for growth), Hydrophobic (best with little moisture). Carbon, Use carbon dioxide as source or us organic material as source of carbon, Oxygen: Aerobic, Anaerobic, Facultative and Obligate Anaerobes |
|
|
Term
| What are chemical requirments for Microbial growth in Water |
|
Definition
| Carbon: some micro organisms use carbon dioxide as their source of carbon. |
|
|
Term
| What are different types of elements of microbial growth regarding chemical requirements and oxygen |
|
Definition
| Aerobic - Needs oxygen to live, Anaerobic - live without oxygen, Facultative - Anaerobes that can survive with or without oxygen, obligate anaerobes- die if exposed to oxygen |
|
|
Term
| What methods used to control microbial growth |
|
Definition
| Microbial growth that ccan be controlled by physical methods, chemical agents or sterilization |
