Wake-up 1.Explain antibacterial resistance. 2.How do bacteria become resistant to antibiotics?
Bacteria II: Diversity
Six Kingdoms of Life Archaebacteria Prokaryotic Unicellular Autotroph/ Heterotroph
Archaebacteria: Characteristics Aka: Extremophiles Live in environments that were thought unable to support life
Examples: Thermophiles Heating Loving Bacteria: Can live in environments up to 284°F
Where are they found? Thermophiles can be found in: Deep sea thermal Vents
Where are they found? Thermophiles can be found in: Active Volcanoes
Where are they found? Thermophiles can be found in: Hot Springs
Closer………….
And Closer……….And Closer………..
Examples: Methanogens Anaerobic bacteria that feeds on decaying organic material, producing water and methane gas
Where are they found? Methanogens can be found in: Bogs and Marshes
Where are they found? Methanogens can be found in: Landfills
Landfill gas consists of about 50% methane, which is flammable.
Where are they found? Methanogens can be found in: Guts (Intestines) of Animals such as Humans, Cows, Horses, and TermitesTermites
Examples: Halophiles Salt Loving/Photosynthetic Bacteria: They live in environments with VERY high salt concentrations
What is VERY high salt concentration mean? Normal ocean water has a salt level of 30 percent. They live in environments containing 10 times the salt of the ocean.
Where are they found? Halophiles can be found in: The Great Salt Lake, Utah
Where are they found? Halophiles can be found in: The Dead Sea
Where is the Dead Sea?
Many people travel to the Dead Sea to swim in the salt and cover themselves with its mud….it is thought to heal
It is also VERY buoyant!!!

Six Kingdoms of Life Eubacteria Prokaryotic Unicellular Autotroph/ Heterotroph
Eubacteria: Characteristics Aka: True Bacteria They can be present anywhere and everywhere They are the most numerous organisms on the planet.
Example: Bacillus anthracis Aka Anthrax; a deadly disease in cattle and a potential bioweapon against humans
Where does it come from??? In nature, it's found in spores in soil around the world
Where are the effect of Anthrax? Inhalation (you breathe it in your lungs) Respiratory problems and infections within the body
Where are the effect of Anthrax? Ingestion (you consumed it) Sores in the mouth/throat, nausea, diarrhea
Where are the effect of Anthrax? Cutaneous (within the skin) Creates sores; sometimes large.
Anthrax and 911: Bioterrorism Anthrax spores where mailed to several individuals, with the hopes of contamination
Example: Salmonella Type of food poisoning; Every year approximately 40,000 cases in the United States
What causes it? Beef, poultry, milk, and eggs are most often infected Food may be contaminated during food processing or food handling Reptiles, baby chicks and ducklings, and small rodents such as hamsters are particularly likely to carry
Where are the effect of Salmonella? Diarrhea, Fever, and Abdominal Cramps
