The roll of Bacteria in our World

By: Laurence Fairchild

What is bacteria?

Bacteria tiny one-celled microorganisms that can either be parasitic or free living. They are organisms with only one cell and no nucleus and they reproduce by cell division. They are found in many different shapes, ranging from spheres to rods and spirals. Some bacteria can infect human beings, plants, and animals, and cause diseases, while others help our environment. Bacteria is extremely useful to our planet, and without it, everything would be dead.

A War We Need

Coccolithophores are unicellular, eukaryotic phytoplankton that can be seen from space. Although it sounds funny, trillions of these Coccolithophores are in a fight for their lives everyday, a fight with viruses. These viruses, once inside the cell, try to keep it alive as long as possible, making as many duplicates of its self as possible. When the viruses are ready to leave, they flow out in a steady stream, each one able to infect another Coccolithophore.

Coccolithophores are extremely important to the importance of Earth's climate change. Because each one is a plant, they are all capable of photosynthesis, helping reduce Carbon Dioxide levels.

Probiotics (Bacteria #1)

Probiotics, often called friendly bacteria, are live, lactic-acid producing microorganisms that are similar to those found in the human digestive tract. This bacteria is very beneficial and is associated with numerous health benefits. They are also widely used in clinical nutrition and complementary alternative medicine. Experts at the National Institute of Health note that probiotics show some promise in the treatment of diarrhea, irritable bowel syndrome, vaginal infections, tooth decay and skin disease. Probiotics do not get enough credit for how much they help us.

Streptococcus pneumoniae (Bacteria #2)

This killer is responsible for numerous cases of pneumonia throughout the world, and equally as important, is the main cause of bacterial meningitis, a killer in its own right. The body has a normal amount of this flora in its respiratory system but when the immune system is compromised or something occurs to disrupt it, this transforms into a virulent bacteria capable of killing those affected. It is an extremely lethal bacteria and people should be aware of the cause it can harm.
