The second Kingdom of life is Eubacteria. Eubacteria are unicellular prokaryotes. The main phylum are organized by how they obtain energy. This kind of bacteria can live in a variety of places. Both Archaebacteria and Eubacteria include the greatest numbers of living things on earth. They are like archaebacteria but are different in thier RNAs, rRNAs, and RNA polymerase structures.

Heterotrophs- This type of bacteria is almost found anywhere. This kind of bacteria gets energy by organic molecules. Some are parasites, and obsorb nutrients from other organisms. Some may also be syrobes which recycle nutrients from decomposing organisms. Which in return are brought back into the environment.

Autotrophs-This type of bacteria are photosynthetic autotrophs. They can make thier own food and energy source. They are common in ponds, lakes, streams and moist areas of land.

Chemotrophs- The third phylum is the chemosynthetic autotrophs. This type of bacteria gets thier energy by breaking down inorganic substances. These organisms can be important because they can convert nitrogen to the atmosphere.

Streptococcus pyogenes

An example of Eubacteria would be Streptococcus pyogenes. The genus name is Streptococcus and the species name is pyogenes. Streptococcus pyogenes is one of the most frequent pathogens of humans. This eubacteria can be found in a wide range of hosts including horses, humans, cows, and pigs. Streptococcus is mainly known as Strep Throat. This eubacteria replicates usually in the mouth or nasal area. When the bacteria comes in contact with vulnerable tissue, a variety of infections can occur. Streptococcus are usually isolated from the mouth and are the dominant bacteria of this habitat.

  • HABITAT: Human upper respiratory tract and skin. Spread by contact and airborne routes. Can survive in dust.

  • EAT: This bacteria can eat flesh if the infection is really severe. If a strain of S.pyogenes enters it destroys macrophages. It usually attaches to mucus and feeds off of the membranes in the throat.
