Today, Mr. Paek reminded us that their is a quiz tomorrow. The disease of the day is cholera plus we also watched a video on cholera. Here are the facts of cholera in haiti.

CHOLERA

1. Bacteria
2. endemic/diarrheal
3. transmission through contaminated food or water
4. targets intestines epithelial cells
5. treated with antibiotics
6. prevented by purified water, sewage treatment, and proper cooking
7. 100,000-200,00 deaths/year world wide

the cholera virus

These were the notes we took today in addition to a hand out he gave us about bacteria.

Bacteria

1. unicellular prokaryotes [lack a nucleus] or other membrane bound organelles


2. 
   
   Contain a cell wall


3. 
   
   Bacteria are separated into 2 kingdoms eubacteria[common bacteria] and archaebacteria

Eubacteria- exists almost everywhere has cell wall made of peptidoglycan.[a carbohydrate]

This is a picture of Eubacteria.

Archaebacteria- live in harsh environments and have a cell wall that lack peptidoglyc an.

Here is a picture of of Archaebacteria.

Shapes of bacteria

1. Bacilli [rod shaped] picture
   

2. cocci [spherical shaped] picture

3. sprillum [spiral] and corkscew shaped] picture

METABOLISM[ENERGY]

1. heterotrophs- obtain energy from organic molecules
2. Autotrophs- make their own food from in organic molecules
3. Phototroph- make own enrgy from light
4. chemotroph- lives of energy from chemicals
   
5. saprophytic- live of dead or decaying organic matter[decomposer]

METABOLISM[RESPIRATION]

1. obligate aerobes- organisms that require a constant supply of oxygen
2. obligate anaerobes- organisms that do not require oxygen and some die with oxygen
3. facultative anaerobes- organisms that can survive with or without oxygen
   

At the end of class we watched a video on bacteria.
