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
